Appendix A

A.1 Introduction

Five practical case studies have been constructed to illustrate the application of the HACCP Principles to different areas of food and drink production and preparation. The authors of these case study examples are people within the food and drink industry, who have hands-on experience of implementing HACCP. Each example has been carefully chosen so that this appendix represents a wide range of process environments and technologies, and products have been included which are normally considered 'high' or 'low' risk from the product safety viewpoint.

Case Study 1 Paella - large scale manufacturing, hands on - high risk. Case Study 2 Hamburger preparation - hands-on in fast-food restaurant - high risk. Case Study 3 Lime juice cordial - large-scale manufacturing, automated - low risk. Case Study 4 Potato salad - retail sale, delicatessen and salad bar -low risk. Case Study 5 Fresh cream gateaux - large-scale manufacturing, hands-on - high risk.

Some points to consider when looking at the case studies are:

• Several different styles are represented. HACCP does not always have to be documented in the same regimented way, but can follow a company style.

• HACCP Teams do not always use the CCP Decision Tree, and may rely on the experience of team members. However, when it is used, the decision tree is a great help in structuring thinking and checking decisions.

• Scope of the HACCP Study must always be clearly defined. All

case studies cover safety hazards, but Case Study 1 only looks at microbiological safety hazards, and Case Study 3 has its scope expanded to cover spoilage in addition to safety. In this example note that only the points critical to safety are called CCPs.

Note: each case study detailed here is theoretical and the findings may not be exhaustive. The contributors are experienced in the products concerned, but the case studies are not necessarily identical to their own company approaches. The examples are not intended as specific recommendations for similar processes/ products, but as a demonstration of the application of the HACCP Principles.

A.2 Case Study 1 - Paella T. Mayes, Unilever Research Laboratory, Col worth House, England.

A.2.1 Limitations

For reasons of confidentiality some specific aspects of this case study, including the product description, are hypothetical. The overall approach taken is, however, based on a real manufacturing operation.

A.2.2 Case Study

208

(a) Background

The company concerned (a small specialist manufacturer of chill­stored products) decided to move into the chill, ready-to-eat market and carried out a series of modifications to the factory environment in order to introduce a High Hygiene Area. During product commissioning trials, a HACCP Study was carried out in order to ensure that product safety could be assured. Company management fully supported the HACCP Study.

(b) The HACCP Study Team

The HACCP Study Team consisted of the following:

(i) Company Quality Assurance Manager (ii) Production Supervisor

(iii) Production Engineer (iv) Factory Microbiologist (v) An external Chairman familiar with HACCP

(vi) A Technical Secretary

temperature in the product assembly areas is 10 cC. Product flows logically through the factory.

(h) Hazards of concern

For the purpose of the case study the hazards of concern to the safety of the final product are considered to be:

B. cereus Salmonella spp. L. monocytogenes E. coli )

Infectious vegetative pathogens (IVP)

A.2.3 Identification of Hazards, Preventative Measures, CCPs, Critical Limits, Monitoring and Corrective Actions

Each process step was discussed by the Study Team and hazards and Preventative Measures identified. The CCP Decision Tree was then used (Table A.l) to identify those process steps that were Critical Control Points - see explanations below. Finally, Critical Limits, Monitoring and Corrective Actions were identified for each CCP. All control data are recorded in Table A.1.2.

Note: in some cases different answers can be obtained from use of the CCP Decision Tree, but this should not affect the identifica­tion of CCPs.

A.3 Case Study 2 - Hamburger preparation in a fast-food restaurant D./. Phillips, Grand Metropolitan Foods Europe, Uxbridge, England.

A.3.1 Introduction

Because the HACCP process is more commonly used for food manufacturing situations where there are usually several discrete processing steps it may appear more difficult to apply to restaurant operations. Generally speaking, there tends to be more product handling in a restaurant operation than in a manu­facturing situation and fewer 'process steps' and perhaps a greater opportunity for cross-contamination. It is therefore essential that proper precautions are taken to ensure that food is safe when presented to the consumer. Bryan (1981) quoted a survey carried out in the USA, which identified the 10 most common contri­butory reasons for food poisoning associated with all types of restaurant operations as being:

• Improper cooling • Twelve hours or more between preparation and eating • Infected people handling food • Inadequate reheating • Improper hot holding • Contaminated ingredients • Food from unsafe sources • Improper cleaning of equipment • Raw/cooked cross-contamination • Inadequate cooking

A HACCP approac.Q. aimed at identifying all potential hazards associated with materials, recipes, processes, and product handling, and establishing Critical Control Points to eliminate or reduce the hazards to an acceptable level, is as relevant in restaurant management as it is in food manufacturing.

A.3.2 Hazard analysis of product formulation

A HACCP Study of the recipe should be used to identify:

1. Any potential hazardous ingredients, which would require processing in the restaurant to make them safe.

2. The potential for any of the ingredients to become hazardous during storage in the restaurant or as a result of cross­contamination.

217

Appendix A

3. All of the time/temperature profiles for both storage, process­ing and product holding.

The two most important factors affecting product safety of ingredients before their use in the restaurant are the adequacy of the Supplier Assurance procedures and the distribution and storage conditions. Ingredients must only be purchased according to strict specifications from suppliers that are capable of managing food safety, and who preferably are applying HACCP to their own manufacturing processes. Suppliers must be audited regularly to ensure their compliance with the product specification and their overall quality system.

As can be seen from the ingredients table in the example given, the meat and the bun are the only ingredients that are actually further processed in the restaurant and therefore the integrity of the ingredients at delivery plays a major part in ensuring that the finished product is safe for the consumer. A hazard analysis of the individual ingredients and the preventative measures required at the supplier are shown in Table A.3.

A.3.3 Critical Control Points in product preparation

218

An example of the process steps that occur during hamburger preparation is shown in Table A.4.

As with any HACCP Process it is very important to validate that the process sequence is correct and is actually what is happening in the restaurant, particularly to ensure that no steps have been omitted. Similarly, it is important to see how product is moved around the restaurant, how the hygienic practices of the employees is working, and how equipment is cleaned and stored before use.

Each step of the process must then be studied in detail to identify the presence of hazards or factors that could lead to hazards occurring, and identify the points at which control can be applied, together with the Critical Limits, the Monitoring Procedures and Corrective Actions. A hazard analysis of the process is shown in Table A.5.

The hazard analysis confirms that the critical control points fall into three categories.

1. Prevention of cross-contamination of bacteria or foreign matter either by product-to-product or people-to-product routes.

2. Prevention of microbiological growth through abuse of storage holding times and temperatures.

3. Cooking of raw products such as beef to destroy any patho­genic organisms that may be present. In fact, beef is the only product used for hamburgers in the restaurant that is processed to make it safe and this fact reinforces the importance of an effective Supplier Assurance programme for all products to ensure that all potentially hazardous foods and ingredients are properly identified and processed by the supplier to ensure their safety.

HACCP Case Studies

Cross-contamination of products with microorganisms from raw unprocessed food or from staff poses one of the major potential hazards in any restaurant and must be prevented by identifying:

(a) Procedures and practices which may contaminate potentially hazardous foods;

(b) Environmental conditions that may allow the growth and transfer of microorganisms on food contact surfaces.

Typically, such cross-contamination is prevented by:

• use of colour-coded tongs for handling raw and cooked meat, chicken and fish

• three-sink system for washing, rinsing and sanitizing all utensils

• regular use of sanitizers for wiping all product contact surfaces • stringent application of hand washing and hand sanitizers • wherever possible, avoiding the introduction of potentially

hazardous raw foods such as whole eggs, raw chicken or fish into the restaurant

Control of storage times and temperatures is essential to avoid the uncontrolled multiplication of any bacteria that may be present. This is achieved through:

(a) defining shelf lives and storage conditions of all incoming ingredients, and ensuring that these are adhered to during distribution;

(b) operating to strict 'First in, First out' (FIFO principles; (c) defining maximum preparation times and discard times for all

products within the restaurant, at all relevant stages of preparation and providing an easy-to-follow system for restaurant staff;

(d) providing hot holding units and steamers capable of maintaining temperatures of >60 dc.

For beef patties, which are produced from 100% beefthat has been formed and frozen, cooking in the restaurant is the major control point assuring the absence of pathogens in the finished ham­burger. Raw beef may contain Salmonella spp., Staph. aureus, and E. coli 0157, all of which can be effectively destroyed by thorough cooking. However, control still has to commence with the patty manufacturer and with the suppliers of the original beef

227

Appendix A

to mInImIZe the presence of pathogens, and monitoring pro­grammes, specifications and auditing of Good Manufacturing Practices at the manufacturer should all be in place. Cooking temperatures are therefore strictly controlled with all of the meat being cooked to a minimum internal temperature of 68°C. Broiler speeds are calibrated before start-up and temperatures are regularly checked throughout the day.

A.3.4 Monitoring

Monitoring of all food safety control points can be carried out through the use of check lists which can be used by the restaurant manager. Monitoring of product quality is also carried out throughout the supply and distribution chain to ensure that product specifications, shelf life and temperature criteria are being rigidly complied with. All of the operating procedures are detailed in an Operations Manual which specifies all food safety items, operating procedures and corrective actions.

A.3.S Record keeping

The monitoring of the CCPs must be properly documented and recorded in a suitable format, validated and signed by the responsible person. Records should be kept for at least 1 year.

A.3.6 Verification

228

HACCP Systems must be verified to ensure that they are working effectively and should aim to establish that:

(a) appropriate control points have been established to control all known potential hazards;

(b) control measures are working effectively.

Verification is carried out in a number of ways. Firstly, verifica­tion of control points associated with supplier and distribution control is carried out by regular audits of all suppliers and distributor records, quality ~ystems, HACCP Systems, as well as GMP audits. Secondly, at the restaurant level, a team of in depend­ent auditors carry out regular audits of every restaurant, checking that every control point is in place and that all Critical Limits are being adhered to. These audits are very detailed and any critical safety factors are highlighted for immediate attention. Thirdly, any customer complaints are systematically analysed to ensure that all hazards have been identified and are being controlled.

Managing food safety effectively is crucial for the success of

HACCP Case Studies

fast-food businesses; the HACCP Principles of identifying potential hazards and implementing appropriate control measures provide the most efficient means of maintaining such management.

A.4 Case Study 3 - Lime juice cordial N.S. Hagger, Britvic Soft Drinks Ltd., Chelmsford, England.

AA.l Introduction

This case study will provide an insight into the institution of the Hazard Analysis Critical Control Point (HACCP) system, as applied within Britvic Soft Drinks Ltd., through looking at a hypothetical unpasteurized soft drink product - lime juice cordial. Britvic are using HACCP for the control of microbio­logical, chemical and foreign body hazards, and to prevent product spoilage in addition to food safety. The Britvic HACCP System is illustrated in Figure A.2.

A.4.3 Stage 2 - Flow Diagrams and Hazard Analysis

230

The Hazard Analysis stage consists of identification and descrip­tion of potential hazards, followed by the assessment of risks associated with the process.

Hazards associated with foods and drinks are normally categorized as microbiological, chemical and foreign body or physical hazards. It is important to note that for this case study, the definition of Hazard is a potential to cause harm in the product in terms of food safety and spoilage.

In order for the HACCP Team to be able to progress towards hazard analysis, first they ·complete accurate Process Flow Diagrams. The HACCP Team 'walk' the entire process before, during and after completion of the flow diagrams. Flow diagram 1 summarizes processes from raw material receipt to final product delivery for all soft drink products made on this production line. The aim of this Flow Diagram (Figure A.4) is to tune the team into a common understanding of what the production site does and where processes occur on the site.

HACCP Case Studies

Copies of relevant engineering diagrams are useful for finer details, which can be transferred in a simplified form to Flow Diagram 1.

Flow Diagram 2 (Figure A.5) details the process of the specific soft drink being considered for this study, i.e. lime juice cordial. The HACCP Team now use their combined knowledge and expertise to describe each activity or operation in its logical sequence in the Flow Diagram, and detail is most important. For the purposes of this case study a basic, non-complicated Flow Diagram has been constructed.

Once both Flow Diagrams are complete, relevant specifications for raw materials, packaging, finished products, storage and delivery are collected together for team use. For this case study, much of the additional information is detailed on the Product Description Sheet (Figure A.6).

Before the hazard analysis stage, the team members familiarize themselves with existing documentation and specifications to understand the process thoroughly and establish what is already in place. The information considered from existing documenta­tion was that:

• the temperature of product throughout manufacturing is ambient;

• the process time is 15 minutes at the batch stirring stage, followed by 1 hour to package the batch;

• there are no 'dead legs' present in the production line; • there is no rework mechanism; • the high-care areas include dry pack weighing, batch prepara­

tion and product filler to capper; • the storage of glass bottles is in cardboard boxes in the enclosed

warehouse before distribution; • the cleaning of the process lines is by steam, Cleaning in Place

(CIP) and manual breakdown of pipework. The cleaning solution is caustic based.

Starting at the beginning of Flow Diagram 2, each part of the process is taken in order and entered onto the 'part of process' section on the Hazard Analysis Table (Table A.6).

Each potential hazard is then analysed by considering the severity and the likelihood of its occurrence. In other words, each potential hazard is investigated in detail to establish whether or not it is a real hazard.

In Britvic Soft Drinks, the HACCP Team carry out the hazard analysis by assigning specific levels of concern to each potential hazard. These concern levels relate to the Britvic operation and

help the HACCP Team to think about what would happen if the potential hazard occurred - would it have a serious outcome or not? The concern level assigned is then used to determine the real hazards, for example, Concern Levell, the hazard is not realistic -rising to Concern Level 4, there is a real hazard.

Looking more closely at the information on the Hazard Analysis Table (Table A.6), this HACCP Study of lime juice cordial gives some interesting information. Picking out some of the points will show how much useful data has been gathered so far.

1. Mains water contains microbial levels that may affect final product quality.

2. If any of the raw materials used in manufacture of the soft drink are chemically contaminated the highest severity of risk will be realized, i.e. this is a food safety issue.

3. Foreign bodies may enter the process via the raw materials, e.g. debris in water.

4. Microbial growth in sugar needs to be minimized as this type of yeast growth will potentially go on to ferment the final product, leading to product spoilage.

5. The cleaning process needs to be able to remove excess surface contact chemicals in the sugar silos and the filler.

6. The syrup room process of additions to the batch tanks is a critical area - the wrong raw material chemicals must not be used in batch make- up, also the batch is at the stage when the product is most at risk to foreign bodies from human error.

7. The microbial contamination from the capper process could allow all products on line 1 to have mould spores added to each bottle, again causing product spoilage.

237

Appendix A

8. The crimper, if not carefully maintained, could allow two hazards to be realized: if over-crimping occurs, neck ring glass may be added to bottles, while under-crimping may lead to air ingress into the bottles, potentially causing microbial growth.

9. Foreign-body debris in the non-return bottles needs to be effectively removed or detected.

The Team have been able, through Hazard Analysis, to identify potential hazards by preparing Flow Diagrams and to assess the severity of each hazard by considering the likelihood of that hazard occurring and the risk to the consumer and/or product. The Team then define controls which are relevant and cost effective to control each hazard.

AAA Stage 3 - Control of Critical Points

238

Following the Hazard Analysis the HACCP Team go on to select those areas as critical for control of food safety, i.e. Critical Control Points (CCPs) - those areas where realistic hazards must be controlled. Control points critical for control of product spoilage are also identified. These are classed as Quality Control Points (QCPs).

The Control Point Information sheet (Tables A.7 and A.8) is completed by selecting from the Hazard Analysis Table (Table A.6) all parts of the process that present a realistic hazard. The remainder of the sheet is then filled in by the Team for each CCP.

The means of control has to be as simple and effective as possible, and once specific parts of the process have been selected either as CCPs or QCPs, the department responsible must be identified. The relevant control systems are then put in place, if not already present.

The key information the HACCP Team have now generated is a clear definition of 'what', 'when', 'where', 'who' and 'how' for each Control Point. These data are then drawn together to document responsibilities and actions in work instructions, such as cleaning schedules, hygiene programmes, and calibration regimes. Documentation is part of the Factory Quality system and is therefore developed in line with the Company's agreed approach to documenting the CP activities to ISO 9000 standard.

The HACCP Team, by using the Control Point Information Sheet (Tables A.7 and A.8) for the production of lime juice cordial, has found 19 Control Points, 10 of which are CCPs associated with chemical contamination or glass faults and debris in the bottles. This is because, with a pH of 2.4, a high sugar content and added preservative the risk of microbiological food

Appendix A

safety issues are small. An additional nine control points were found to be QCPs for the control of spoilage microorganisms (predominantl y yeasts).

AA.S Stage 4 - Recording

Examples of recording are not included in this case study.

AA.6 Stage 5 - Continuous improvement

Following implementation of HACCP to Stage. 4, recording of information is extremely important to keep the momentum of the System going. In addition, new products, new packages and new processes will inevitably be introduced to a factory and or production line, which will introduce potential new hazards. These new hazards need to be incorporated into the HACCP Study so that new CCPs can be identified and redundant CCPs rejected. This means that a regular review is needed.

The HACCP Team would carry out Stage 2 'The Hazard Analysis' incorporating any potential new hazards, changes to the Flow Diagrams and the Hazard Analysis Table. Depending upon the significance of the hazard, this may be carried out by (i) completely redoing the Hazard Analysis Stage; or (ii) inserting the relevant details onto the existing paperwork. Whichever method is selected, copies of all originals should be maintained for reference. By retaining original copies, historical information is provided for reference in the event of a hazard being realized or if a similar situation arises in the future.

If new CPs are identified, the HACCP Team carry out Stage 3 incorporating the new CPs on the Control Point Information Sheet (Table A.7). Depending on the significance of the hazard, this could mean that the Control Point Information Sheet may need to be (i) completely redone; or (ii) have new/altered CPs inserted. Stage 4 Recording then needs to be updated, and set up for new CCPs as necessary.

Records of HACCP information will eventually build up, and local decisions are made at each factory as to which information is retained.

AA.7 Stage 6 - Auditing

242

The auditing of the whole HACCP System ensures that all Critical Control Points are under control and that any corrective action needing to be implemented is carried out. Auditing is therefore

HACCP Case Studies

part of the continuous improvement plan following the imple­mentation of HACCP. Each department should have a list of CPs relevant to the department's function. The Britvic auditing process is presently carried out by someone external to the site, to ensure the HACCP work is running smoothly and the CPs are being monitored by the relevant departments.

The auditor views and records his or her findings when he or she is satisfied that CPs are being actioned through work instructions, cleaning schedules, hygiene programmes and calibration regimes. The result of the audit is entered onto audit sheets. The Control Point Sheets themselves can be extended and used for this purpose by adding additional columns for audit data and results.

The results of the audit are then discussed with relevant personnel; this may be the whole factory management team or the quality management. An audit performance rating will be given when the auditor has assessed all stages of the HACCP system, i.e. Control of Critical Points, Recording and Continuous Improve­ment. Copies of audit records are retained by the auditor and factory manager, and a copy is forwarded to the company HACCP Co-ordinator .

In conclusion, the production of soft drinks, with regard to microbial food safety, is considered within the food and drink industry as low risk. However, this case study has briefly shown how manufacture of any product may, through Hazard Analysis of the process and Control Points identification, be used to control not only the risk to food safety, in this case particularly chemical and physical hazards, but also to product spoilage, thus ensuring consumer satisfaction.

A.5 Case Study 4 - Potato salad, retail sale C.A. Wallace, with assistance from J. Hughes, J. Sainsbury plc, London, England.

A.5.l Introduction

This case study covers the introduction of a new product to the delicatessen and salad bar counters of a retail supermarket. Hazard analysis had previously been carried out on existing salad products, and the main purpose of this study was to ensure that no new hazards would be introduced which would not be controlled effectively by the existing control mechanisms.

Appendix A

A.S.2 HACCP Team members

The HACCP Team was made up of the following:

• Store Food Safety Officer - Team Leader • Delicatessen Manager • Warehouse Manager • Head Office Technologist

All Team members had a minimum of 3 years' experience in the retailing of fresh food, and had received training in the applica­tion of HACCP.

A.S.3 HACCP Study Terms of Reference

The HACCP Study covers food safety hazards from receipt by the store warehouse to consumption by the consumer. The potato salad had already been established as a safe product when supplied, and was covered during manufacture by the supplier's HACCP Plan.

This HACCP Study does not cover spoilage. The HACCP Team proposed to address this separately due to time constraints. As spoilage microorganisms can grow in the product, then storage times and temperatures will become more important, along with the cross-contamination risk, when the spoilage study is carried out.

A.S.4 The Product

244

The product is a low-pH, chilled potato salad, made up of cooked potato and mayonnaise, and garnished with chives. It is manu­factured by an existing approved supplier of prepared salads. The product characteristics are as follows:

(i) pH - 4.0 ± 0.1 (ii) Storage temperature - <5.0 °C

(iii) Pack size - 2 kg (iv) Pack type - plastic tub with lid (v) Shelf life - packed product, 15 days at <5.0 °C;

once opened, 4 days at <5.0 °C

The product formulation will not support the growth of pathogens due to its low pH. However, the potential for contamination with pathogens which may survive, and in particular those which have a low infective dose (e.g. Salmonella spp.) will need to be considered during the HACCP Study.

Appendix A

A.5.7 Controlling the CCPs

250

The HACCP Team found that the CCPs identified were all already in place for other salad products on both the delicatessen and salad bar counters. As no new CCPs were required, it was decided not to construct a HACCP Control Chart specifically for this product, but to add it to the existing documentation. A summary follows for the control of each hazard type requiring a CCP.

(a) Hazard - cross-contamination with pathogens from bowls and utensils Hazard - chemical contamination from cleaning residues

The Preventative Measures for both of these hazards, which occur at several places in the operation, are similar. Effective cleaning procedures, which are carried out properly by trained staff, are essential to prevent these hazards. The Critical Limits are that each item has been effectively cleaned before each use. This could be monitored on an ongoing basis by the delicatessen staff and intermittently by their supervisor, using visual inspection. Corrective action will include not using any items which have been inadequately cleaned, and retraining staff where appro­priate.

(b) Hazard - cross-contamination with pathogens from staff practices Hazard - cross-contamination with foreign material from staff and environment

The Preventative Measures for these hazards involve hygiene procedures for both staff and environment, also known as Good Manufacturing or Good Retail Practices (IFST, 1991). These procedures will control the availability of items which may enter the product as foreign material, as well as the design of equipment and practices to prevent ingress, eg the covering of bowls during the transfer to the salad bar at process step 9. In addition, the personal hygiene procedures will reduce the potential for cross­contamination from staff.

For effective control of these hazards, the required procedures must be in place and staff must be fully trained. In other words, the Critical Limit is that the procedures are carried out effectively on an ongoing basis. This type of procedure would be monitored on an ongoing basis through visual inspection by the staff themselves and their supervisors, and through intermittent audits

HACCP Case Studies

by the store Food Safety Officer and Head Office technologists. Corrective action would include immediate correction of any fault and retraining of staff where necessary.

(c) Hazard - cross-contamination with pathogens or foreign material from customers at the salad bar

The Preventative Measures for these hazards relate to the effective design of the salad bar counter, and it is important to get it right before it is brought into use. The main factors are the height of the counter, guards to protect the food and ease of cleaning. Once these have been designed in, the counter requires continuous visual monitoring and action must be taken to correct any fault which is identified.

Note: in every case described above any deviation from the critical limits are recorded in the counter log book, along with the corrective action taken. This is signed off by the member of staff and their supervisor.

A.S.B Implementation and maintenance

Since the CCPs required are already being implemented for other products on both the delicatessen and salad bar counters, the potato salad product can easily be slotted into the normal management plan.

Maintenance requirements are fulfilled by monthly audits of the systems by the store Food Safety Officer, and by an annual in­depth food safety audit by Head Office technologists. At both of these audits the non-compliances and corrective action log book is reviewed and signed off.

A.6 Case Study 5 - Fresh cream gateaux S.E. Mortimore, with assistance from the Memory Lane Team, at Cardiff, Wales.

A.6.1 Introduction

This case study covers the large-scale production of a fresh cream and jam gateau.

251

Appendix A

A.6.2 HACCP Team members

The RACCP Team was organized as follows:

1. Core team • Factory Production Manager • RACCP Officer • Engineering Manager

• SQA Technologist 2. Co-opted members • Cream and Jam Line

Supervisor • Microbiology Manager

A.6.3 Terms of Reference

252

The RACCP Study covers food safety hazards of all types -biological, chemical and physical. The RACCP Study did not include any cleaning operations; this was considered in a separate RACCP Plan.

A.6.4 Product description

Fresh cream and jam gateau Facility

HACCP Case Studies

The purpose-built factory produces a variety of decorated gateaux for sale to the retail industry. The factory is based on a large new industrial estate and produces both chilled and frozen products.

The product

The product has a fresh cream and jam filling between two sponges. It is a chilled product and must be kept below 5 °C through the distribution chain. The shelf life is 3 days from date of manufacture.

Manufacture

Sponge batters are baked at ISO-170°C through a travelling oven for 18.5 minutes. They are then cooled to ambient, automatically sliced and filled. There is a wide variety of fillings for the sponges. The sponges are flow-wrapped and put into cartons.

Principal hazards and preventative measures

Principal biological hazards are the potential presence of pathogens in various ingredients and cross-contamination during processing. Preventative Measures include approved suppliers and certificates of conformance, sensitive ingredient testing, baking and segregation.

Intended use

The product is targetted at the general public and may therefore be consumed by high-risk individuals. Salmonella and Listeria control is therefore critical.

Appendix A

A.6.8 CCP monitoring

As the HACCP Team expected, the control measures identified during the study were currently in place with the exception of having the Water Authority test a local (factory) sample of water. New log sheets were drawn up for each CCP, each cross­referencing the HACCP Plan number. CCP 'monitors' were given briefings to explain the significance of CCPs on introduction of the new log sheets. They were also retrained in Corrective Action Procedures.

A.6.9 HACCP Plan maintenance

264

The company HACCP Officer was asked to maintain an audit schedule for the HACCP Plan and each core team member was trained in audit techniques. As the Plan has only nine CCPs, it was decided to carry out a formal audit every month alongside the company formal GMP audit.

The audit includes a review of CCP log sheets, SQA audits, Certificates of Analysis, Corrective Actions taken and the status of any ongoing Improvement Programmes. The results of the audits are discussed at the subsequent board meetings.

Appendix B

Examples of practical hazard control

Hazard

Hazard category: Biological Heat-stable pre-formed toxins, e.g. Staphylococcus aureus, Bacillus cereus emetic toxin

Vegetative pathogens, e.g. Salmonella spp., L. monocyto­genes, V. parahaemolyticus, Y. enterocolytica, etc.

cont'd

Preventative measures

~a\V materials • Specification for organism and/or toxin • Evidence of control during supplier

process • Testing • Certificate of analysis

People • Hand wash procedures • Covering cuts/wounds, etc. • Occupational health procedures • Management control of food handlers

Build up during process • Control of time that ingredients, intermedi­

ate and finished products are held \Vithin the organism's gro\Vth temperature range

• Design of process equipment to minimize dead spaces

• 'Clean as you go' procedures

Ra\V materials • Lethal heat treatment during process • Specification for organisma • Testinga • Evidence of control during supplier

processa

• Certificate of analysisa • Temperature control to prevent gro\Vth to

hazardous levelsb • Intrinsic factorsb such as pH and acidity;

aw - salt, sugar, drying; organic acids; chemical preservatives

• Processesb such as irradiation, electrostatic field sterilization, etc.

265

Appendix B

Hazard Preventative measures

Cross-contamination at the facility (from the environment and raw materials)

• Intact packaging • Pest control • Secure building (roof leaks, ground water,

etc.) • Logical process flow, including where

necessary: (i) segregation of people, clothing,

equipment, air, process areas (ii) direction of drains and waste

disposal

·Critical when your process has no lethal heat treatment bN.B. Salmonella spp may cause infection at low numbers in your product. Therefore absolute confidence in your raw materials as supplied is necessary. Remember also that heat-labile toxins will not necessarily be destroyed by other processes/controls such as irradiation or acidity

Spore formers, e.g. Cl. botu­linum, Cl. perfringens, B. subtilis, B. licheniformis, B. cereus

266

Raw materials • Specification • Evidence of control during supplier

process • Testing • Certificates of analysis • Lethal heat treating during process:

(i) Fo3 process required for low acid products for ambient storage

(ii) Lethal combination of heat treat­ment and acidity or sugar level for high acid/sugar products for ambi­ent storage

(iii) For products to be stored at chilled conditions « 5°C) a sub-lethal heat treatment may be used but this must be accompanied by in­trinsic factors which will prevent the growth of psychrotrophic organ­isms (e.g. Cl. botulinum) during the product shelf life

(iv) For all the above processes, pack integrity, cooling water chlorina­tion and cooling container handling are critical

• Temperature control to prevent growth to hazardous levels

• Intrinsic factors such as pH and acidity; aw - salt, sugar, drying; organic acids; chemical preservatives

Hazard

Food-borne viruses, e.g. Hepatitis A, SRSV

Parasites

Protozoa, e.g. Cryptosporidium parvum, Giardia intestinal is (lamblia)

Mould (mycotoxinsj, e.g. patulin, aflatoxin, ergot, tri­cothecenes

Examples of practical hazard control

Preventative measures

• Other processes lethal to the organism of concern, e.g. irradiation, etc.C

Cross-contamination at the facility (from the environment and raw materials)

• Intact packaging • Pest control • Secure building (roof leaks, ground water,

etc.) • Logical process flow, including where

necessary: (i) segregation of people, clothing,

equipment, air, process areas (ii) direction of drains and waste

disposal

• Avoidance of products likely to be grown in sewage-contaminated waters, especially molluscan shellfish

• Strict SQA control concerning irrigation and wash water of salads and vegetables

• Consideration given to proven lethal treat­ments such as irradiation or heat treatment

• Stringent personal hygiene procedures among food handlers

• SQA procedures to include farm animal husbandry and veterinary inspection for control of parasites such as Toxiplasma gondii, Taenia in beef and pork, and Trichinella in pork

• Freezing (-18°C), heating (> 76°C), drying and salting

• Use of filtered water • Pasteurization of raw milk • Heat treatment of water used as an ingredient

• SQA control of harvesting and storage to prevent mould growth and mycotoxin forma­tion in cereals, ground nuts , dried fruit

• Heat treatment during process to destroy mould and prevent growth in product

• Controlled dry storage • Intrinsic factors to reduce aw to < 0.7

"Remember that heat-labile toxins will not necessarily be destroyed by other processes/ controls, such as irradiation or acidity

Hazard category: physical Intrinsic physical contamination of raw materialsd

e.g. Bone - meat/fish Extraneous vegetable matter - fruit stones, stalks, pips, nutshells Glass Wood Metal Plastic Pests

Physical cross-contaminants e.g. Glass

Wood

Metal

Preventative measures

Liquids • Filtering • Magnets • Centrifugal separation

Powders • Sifting • Magnets • Metal detection • Air separation

Flowing particulates, e.g. nuts, dried fruit, IQF fruit and vegetables

• Inspection • Screening • Sifting • Magnets • Metal detection • Washing • Stone and sand traps • Air separation • Flotation • Electronic colour sorting

Large solid items, e.g. carcasses, fish, cabbages, cauliflowers, frozen pastry, packaging

• X-ray detection • Metal detection • Deboners • Visual inspection • Electronic scanning

• Elimination of all glass except lighting, which must be covered - light breakage procedure

• Glass packed products - glass breakage procedures, inversion/washinglblowing of glass packaging before use

• Exclusion of all wooden materials such as pallets, brushes, pencils, tools from exposed product areas

• Segregation of all packaging materials • Equipment design - preventative mainten­

ance

Glossary

Audit A systematic and independent examination to determine whether activities and results comply with the documented procedures; also whether these procedures are implemented effectively and are suitable to achieve the objectives.

Cleaning in Place (CIP) The cleaning of pipework and equipment, while still fully assembled, through the circulation of cleaning chemicals.

Corrective Action Procedures to be followed when a deviation occurs from the critical limits, i.e. the CCP goes out of control.

Critical Control Point (CCP) A point, step or procedure at which control can be applied and a food safety hazard can be prevented, eliminated, or reduced to acceptable levels.

CCP Decision Tree A logical sequence of questions to be asked for each hazard at each process step. The answers to the questions lead the HACCP team to decisions determining which process steps are CCPs.

Critical Limit An absolute tolerance value which must be met for each control measure at a CCP. Values outside the Critical Limits indicate a deviation and potentially unsafe product.

Gantt chart A project implementation timetable. The Gantt chart shows at a glance the timing and dependencies of each project phase.

Hazard A property which may cause the product to be unsafe for consumption.

HACCP Control Chart Matrix or table detailing the control criteria (i.e. critical limits, monitoring procedures and corrective action procedures) for each CCP and preventative measure. Part of the HACCP Plan.

HACCP Plan The document which defines the procedures to be followed to assure the control of product safety for a specific process.

Glossary

HACCP Study A series of meetings and discussions between HACCP Team members in order to put together a HACCP Plan.

HACCP Team The multidisciplinary group of people who are responsible for developing a HACCP Plan. In a small company each person may cover several disciplines.

Hazard Analysis Chart A working document which can be used by the HACCP team when applying HACCP Principle I, i.e. listing hazards and describing preventative measures for their control.

Intrinsic factors Basic, integral features of the product, due to its formulation, e.g. pH, aw .

Monitoring A planned sequence of observations or measurements to assess whether a CCP is under control. Records of monitoring are kept for future use in verification.

PERT chart A diagrammatic representation of the dependency network and critical path to completion of a project plan.

Potable water Wholesome, drinkable water. Preventative measure A factor which can be used to control an

identified hazard. Preventative measures will eliminate or reduce the hazard to an acceptable level.

Process Flow Diagram A detailed stepwise sequence of the operations in the process under study.

Quality Management System A structured system for the management of quality in all aspects of a company's business.

Supplier Quality Assurance (SQA) The programme of actions to ensure the safety and quality of the raw material supply. Includes preparation of and procedures to assess supplier competency, e.g. inspections, questionnaires.

Target level A value within the Critical Limits which can be used to take action and prevent the occurrence of a deviation.

Verification The procedures (other than those used in monitoring) which ensure that the HACCP Study has been carried out correctly and that the HACCP Plan continues to be effective.

Integrated Solid Waste Management: A Lifecycle Inventory P R White, Environmental Scientist, Procter & Gamble Ltd, UK, M Franke, Environmental SCientist, Procter and Gamble GmbH, Germany and P Hindle, Director of Environmental Quality Europe, Procter and Gamble European Technical Centre, Brussels, Belgium

This book combines the two emerging concepts of Integrated Waste Management (IWM) and Lifecycle Inventory. IWM uses a range of treatment options including recycling, composting, biogasification, incineration and land filling, to minimise the environmental impacts from solid waste management, at an affordable cost. Lifecycle Analysis is used to predict the overall environmental impacts of waste management systems, in terms of energy consumption, and emissions to air, water and land.
