• Knowledge of the practices and local requirements in the supply chain

• Data such as monitoring results

• Product characteristics, change in (GMO) varieties

• Climate circumstances (e.g. aflatoxin, wet means drying, etc)

Raw material risk assessment based on

HIGH RISK

MEDIUM

LOW RISK

This means:Risks may vary from year to year(crop to crop)

Pesticides / Chemicals

Fertilizer

Herbicide

Insecticide

Fungicide

• Fertilizer• Treated seeds: Insecticide + Fungicide• Insecticide for bottom insects• Herbicide: weeds

• Herbicide: Generiek•Fungicide: Fusarium, Eyespot

•Fertilizor: Nitrogen

•Insecticide: At aphid contamination Fungicide: Septoria treatment

Herbicide: weeds •fertilizer: Foliar •Insecticide: Sesamia/PyraleMais

Fungicide: Flag leaf protection

Herbicide: Drying of the product before harvest

Pesticides (limits)

Pesticides (oil seeds)

The majority of the pesticides we find (in oil seeds / oil)

are:

Lipophilic / Fat Soluble (F)

and are hardly solvable in water.

Water solvable pesticides are normally flushed away by

rain before the harvest. If present they will end up in the

meals (and sometimes in the oil)

• One of the most common contaminants found in extracted

rapeseed, soya and sunflower oils

• PAH4 and BaP contamination usually comes from the exhaust

residues of poorly maintained direct heat grain dryers, or

dryers using dirty fuels such as heavy fuel oil or diesel

PAH4

Poorly maintained burners often burn with a yellow flame, showing incomplete oxidation of the fuel and causing additional contaminants in the exhaust gasesIn (old fashioned) grain dryers pass the burner exhaust gasses directly through the grains and seeds

PAH4

• PAH4 is group of 4 types of Poly Aromatic Hydrocarbons

• Benzo(a)pyrene

• Chrysene

• Benzo(a)antracene

• Benzo(b) fluoranthene

The sum of above is called “PAH4“

30

PAH4

Food stuffs:

PAH4 as a group in food products is 10 µg/kg

And there is a separate limit for BaP: 2 µg/kg

Feed stuffs:

There is no official limit, but GMP+ has the following limits:

Product Action limit Rejection limit

Oils and fats (excluding palm(kernel)-,

coconutoil and products derived thereof)

Palm(kernel)-, coconutoil and and

products derived thereof)

160 µg/kg

320 µg/kg

200 µg /kg

400 µg/kg

31

Feed safety Bacteria / Salmonella

• 2300 strains of salmonella have been identified but only a few cause problems in humans

• 40% of food poisoning outbreaks are caused by salmonella

Salmonalla is not a problem in oil, but a problem in meal

• Feed limits:Absent in 25 grams

32

Dioxins and PCB’s

The source of dioxins :- Byproducts of PCB production- Waste incineration- Formed by burning hydrocarbons and chloride

PCB’s were used in the past as cooling and insulating fluid for industrial transformers and capacitors

33

Dioxins and PCB’s (Limits)

Food WHO-TEQ

0,75 pg/g

• Moulds and fungi

Often found in cereal grains (and in lesser

extent oilseeds), while not toxic themselves, are often able to produce toxic by-products (mycotoxins)

• Naturally occurring poisons

Found in some weed seeds such as

ambrosia*, mustard, cotton, datura etc

Mycotoxines / Natural Poisons

37

• Moulds and fungi e.g. AflatoxinLimits in Feed: (EU) 574/2011 / 2002/32/EC:

0,02 mg/kg

GMP+ dairy farmer : 0,005 mg/kg

• Naturally occurring poisonsLimits: Most of the cases not detectable

Mycotoxines / Natural Poisons (Limits)

38

Mercury(Hg), Cadmium (Cd),

Lead (Pb), Arsenic (As)

From environmental contamination (field)

Or by admixture e.g. adding soil (adding weight)

Feed limits

Hg (0,1 mg/kg),

Cd (1 mg/kg),

Pb (10 mg/kg),

As (2 mg/kg)

Heavy metals

39

Oil, grease and fuel contamination

• Oilseeds are particularly high risk

as contaminating oil, grease and

fuel will get extracted into the

finished oil products

• Mineral oils, greases and fuels

could contain dioxins, heavy

metals and polychlorinated

biphenyls (PCBs) which are all

highly carcinogenic

• US uses mineral oils for dust

suppression on the soybeans
