BRIEF RESUME OF THE INTENDED WORK
6.1 Need for the study:
“We are what we eat"
Food is any substance or materials eaten or drunk to provide nutritional support
for the body or for pleasure. It usually consists of plant or animal origin, that contains
essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals, and is
ingested and assimilated by an organism to produce energy, stimulate growth, and
maintain life. Through centuries food has been recognized as important for human beings
in health and diseases. The history of man has been to a large extend struggle to obtain
food. the purposes of food are to promote growth, to supply force and heat, and to
furnish material to repair the waste which is constantly taking place in the body. Every
breath, every thought, every motion, wears out some portion of the delicate and
wonderful house in which we live1.
The word ‘Hygiene’ is derived from ‘Hygeia’ the Goddess of Health in Greek
mythology. It is the science of health and embraces all factors which contribute to
healthful living. Food hygiene is a broad term used to describe the preservation and
preparation of foods in a manner that ensures the food is safe for human consumption.
This process of kitchen safety includes proper storage of food items prior to use,
maintaining a clean environment when preparing the food, and making sure that all
serving dishes are clean and free of bacteria that could lead to some type of
contamination2.

Food safety is a scientific discipline describing handling, preparation, and storage of
food in ways that prevent food borne illness. This includes a number of routines that
should be followed to avoid potentially severe health hazards. Food can
transmit disease from person to person as well as serve as a growth medium
for bacteria that can cause food poisoning. Food sanitation rests directly upon the state
of personal hygiene and the habit of personal working in the food establishments. Proper
handling of foods, use of clean utensils and dishes together with emphasis upon the
necessity for good personal hygiene are of great importance in street food industry3.
Food borne diseases remain responsible for high levels of morbidity and mortality in
the general population, but particularly for at-risk groups, such as infants and young,
children, the elderly and the immunocompromised. In order to reduce the incidence and
economic consequences of foodborne diseases, the WHO Department of Food Safety and
Zoonoses (FOS) has been assisting the States to establish and strengthen their
programme for assuring the safety of food from production to final consumption. In this
regard, WHO offers a unique capacity, through its commitment to health, to work
collaboratively with government, industry and consumers, to strengthen and better focus
national food safety efforts4.
The global incidence of food borne disease is difficult to estimate, but it has
been reported that in 2005 alone 1.8 million people died from diarrhoeal diseases. A great
5
proportion of these cases can be attributed to contamination of food and drinking water.
Additionally, diarrhea is a major cause of malnutrition in infants and young children.
According to the centers for disease control & prevention (CDC) food born disease cause
an estimated 76 million illness,325000 hospitalization & 5200 deaths in US each
year .Not only are the symptoms uncomfortable,food born illness can lead to secondary
long term illness. For eg: there are some strains of E.coli that can cause kidney failure in
young children, while salmonella can lead to reactive arthritis &8 serious infections. For
pregnant women the listeria bacteria can cause meningitis & still births5.
Food borne illness is a major public health problem in the United States and globally.
Both the developed and developing countries suffer the consequences of food borne
illness, but to varying degrees. Recent U.S. estimates indicate that some 76 million
illnesses and 5,000 deaths are attributed annually to food borne illness. Among all
illnesses attributed to food borne causes, 30% are caused by bacteria, 3% by parasites,
and 67% by viruses6.
The incidence of food borne illness in developing countries is less well-understood than
in the U.S. Estimates issued by the World Health Organization (WHO)3 that diarrheal
disease caused by the consumption of contaminated food or water is the third leading
cause of death in the developing countries. Estimates for 1998 indicate that 2.2 million
deaths are attributable to diarrheal disease, of which 1.8 million occur in children less
6
than 5 y of age. Overall, it is estimated that 1.5 billion cases of diarrheal disease occur
annually in children under 5 years of age (WHO1999)7.
The term "street food" refers to a wide variety of ready-to eat foods and beverages sold
and sometimes prepared, in public places. Street food may be consumed where it was
purchased or can be taken away and eaten elsewhere8.
The street food industry has an important role in the cities and towns of many developing
countries in meeting the food demands of the urban dwellers. It feeds millions of people
daily with a wide variety of foods that are relatively cheap and easily accessible. The
street food industry offers a significant amount of employment, often to people with little
education and training. Street food vendors are often unlicensed, untrained in food
hygiene and sanitation and work under crude unsanitary conditions. They are mainly
those who are unsuccessful or unable to get regular jobs. At present street vendors are
trained as irritants to urban planning and organization9.
It is observed that the street food vendors have poor practices regarding food hygiene.
Here the health education can play an important role to change their attitude and enhance
their practices.
According to studies done in Africa on street foods, their tremendous unlimited and
unregulated growth has placed a severe strain on city resources, such as water, sewage
7
systems and interference with the city plans through congestion and littering adversely
affecting daily life. FAO further stipulates that street foods raise concern with respect to
their potential for serious food poisoning outbreaks due to improper use of additives, the
presence of adulterants and environmental contaminants and improper food handling
practices amongst street food vendors. Street food vendors are often unlicensed,
untrained in food hygiene and sanitation, and work under crude unsanitary conditions10.
6.2 Review of Literature
The reviewed literatures are presented under the following three main areas.
1. Knowledge of food handlers.
2. Practice of food handlers
3. Structured teaching programme on food hygiene.
1. Knowledge of food handlers.
A study on “Evaluate the food safety knowledge and practice of street food vendors.
Etbara city between March and April 2008. 50 samples were selected by random
sampling techniques, the written questionnaire used in this study is modified version of a
questionnaire from the U.S F.D.A (Food and drug administration). Findings of study
shows the respondents were 28% male 72% female, but 38% of them age 31-40 years and
28% of then were 21 – 30 years old, the educational level of 48% of respondents was
primary schools were as 42% were illiterate. Most of the surveyed people 64% were
married. The sanitary vendors represented 90% the most prevalent isolated bacteria from
cooked meals, bottled drink and fresh juice were E.coli, staphylococcus auerus and
streptococous bacilli. Health and personal hygiene practices of street vendors positively
8
responded for prevention of food born diseases 94%, 96% were responded hand washing
is required and 98% were responded reason for hand washing after eating meals.
Researcher felt that routine medical examination of food handlers must be carried out by
medical personal towards regulating safe street food handling preparation and vending11.
A study on evaluation of F.H know attitude and practices of F.H in food business in
turkey in the year 2004. information uptaine from the sample with the help of structured
interview method. A total no.of samples were participated in study 764 food handlers
9.6% were involved in distributing on wrap food routinely and use protective gloves
during their working activity. A majority of participants (47.8%) had not taken basic
food safely education the mean safety food knowledge score was 43.4± 6.3%. study
shows that food handlers are having lack of knowledge regarding basi food hygiene12.
A study on food safety knowledge and practices of street food vendors in Khartoom city
between March and May 2008. Sample size was 50, information obtained from the
samples by structured questionnaire, questionnaire was prepared on health and personal
hygiene knowledge of vendors and food hygiene and knowledge of food born diseases.
Results shows that respondents were 50% males and 50% were females, respectively
38% in 21 – 30% of age group and 8 was ≤ 20 of age only 44% respondents had non
formal education while 46% had al least primary school education. 50% of street food
vendors are married while 44% were singled. 66% of vendors surveyed were stationary

them acquired through observation, about 73% of vendors had no knowledge need to
wash hands after handling money, very few 14% vendors were aware of that it is
necessary to wash their hand even when hand kerchief was used for sneezing, less than
46% of respondents felt that use of soap is always not necessary for hand washing, but
86% said that use of clean water when washing their hand. It shows that street vendors
had lack of knowledge and the practice regarding food hygiene and food born diseases13.
2. Practice of food handlers
A study on food safety and hygienic practices at street food vendors in owerri, Ngira.
Data collection was down with help of structured interviews, semi structured
questionnaires as well as through observations. A descriptive survey design was used.

A study on Hygiene and sanitary practices of vendors of street foods in Nairobia,
KENYA. The accessible population was all street food vendors from Dandora and
Kayole estates. Data collection was done by using in depth interview schedule and
observational checklist. Data was analyzed using both descriptive and inferential
statistics. It is used to present the findings and also used to test the relationship between
the variables (demographic variables) Results shows that 35% of vendors of belongs to
20-25% 60% were males while 40% were females. Slightly over half of vendors (57.5%)
were married. 62% of vendors were primary education and below, 36.3% had secondary
education while only 1.3% had college education. Most 61% vendors acquired cooking
principles by observation 33.3% were taught by parents while 6.3% gained by trial and
error. Based on observation about 85% of vendors prepared their foods in unhygienic
conditions given that garbage and dirty waste were consciously close to the stalls, about
92.5% did not have garbage receptacles, hence they dispose their waste just near the
stalls. 92% of vendors through waste water just beside the stalls making the environment
surrounding the eaters quite fitting. Hence there is a significant P value > 0.5 indicating
that here was no relation between education and state of environment15.
A study on “Hygienic practices by vendors of the street food “doubles” and public
perception of vending practices in Trinidad”. A structured questionnaire was
administered to 120 street vendors and 115 public members in Trinidad, West Indies.
Most vendors are male (61.7%), had been vending for 5 years (81.7%) and received
primary level of education (72.5%). Preparation of doubles was mainly by family
11
(84.2%) in the morning of vending (81.7%). Vendors were appropriately dressed
(99.2%), used forks/spoons (100%) and tongs (81.7%) for serving. At vending sites,
containers with faucets supplied water (85.7%) and toilets were not close (97.5%). Most
respondents (86.1%) consumed doubles. Some (30.6%) felt ill from eating doubles, but
only 2.7% reported to a medical doctor/health authority. Significant associations were
found for vending practices and sanitation of vending environment16.
3. Structured teaching programme on food hygiene.
A study on “A study about the impact of nutrition education and awareness of food safety
among women self help group members: Data was collected from 150 respondents by
random sampling method. A structured questionnaire was used to obtain the data. The
respondents were divided into control (75) as well as experimental group (75), Food
safely education were imparted to experimental groups. The results of the study shows
there is lack of awareness amongst the self help groups women involving in food
processing trade. So educational materials need to emphasize safe food handling
practices17.
A study on effect of structured teaching programme on knowledge and practices
related to hand washing technique among food handlers. The study was conducted in the
mess of Christian Medical College and Hospital, Ludhiana (Punjab). The main findings
of the study were Pretest mean knowledge scores were found to be 43.7% and post test
mean knowledge score was 83.1% and that of mean hand washing practice score, found
12
49.3% in pretest and 92% in post test. There was no significant relationship found
between knowledge and practices with the variables like age, education, experience etc.
The above findings indicate that food handlers had poor knowledge and hand washing
practices, and structured teaching had been significantly effective increasing their
knowledge and practice scores. She concluded her studies with the recommendation, that
is, to have inservice training to the food handlers, which should be given regularly and
reinforced in working area18.
