Mycotoxins: Milk and Dairy products

(toxin from fungus)FungusAgricultural raw materials and food productsADI of AWI (ug/kg body weight)EffectsLegislatory regulationsComments
Aflatoxin (five species: B1, B2, G1, G2; M1 occurs in milk and comes from B1) and M2 (M1 and M2 are conversion products of Aflatoxin B1, B2 into lactating mammalsAspergillus flavus Aspergillus parasiticusCereals, buckwheat, maize and maize products, cottonseed, , other types of nuts (pistachio-nuts, walnuts), , dried figs, milk (products), sesame seed soy and soy products.Acute toxic; degradation of liver and kidneys. Chronic: carcinogenic (cancer forming) especially in the liver.Maximum levels according to Regulation (EC) No 1881/2006Aflatoxin B 1 is the most common and toxic carcinogen. In milk (products) is the most common aflatoxin M 1 formed after that B 1 is broken down. Around 1-3% B 1 is processed in milk to M 1. M 1 is not as poisonous and carcinogenic as B 1. Next to M 1 are other break-down products of B 1 present in milk. Fungus mostly grows during transport and in the tropics, mostly characterised by high temperatures (optimum 25 °C: range 8-37) and or high (>83%). In developed countries (VS) are aflatoxins mainly caused during difficult growth seasons (growth-stress).
Ochratoxin A&BAspergillus Penicillium speciesBarley, rye, wheat, rice, maize, peanuts, Brazilian nuts, peppers, Cotton seed, Cheese.AWI of toxin A: 0,112 (JECFA, 1990) limit: 10 ug/kg food product. LD 50 (rat, oral) van toxin A: 20 mg/kgMaximum levels according to Regulation (EC) No 1881/2006Toxin A is more toxic than B. In the Netherlands are such low amounts found that the risk is perceived very low and therefore is there no norm. Growth fungus is possible in a temperate climate. Toxin A is inactivated at > 221 °C

Chronic: mutagenic and carcinogenic.
Maximum levels according to Regulation (EC) No 1881/2006In the Netherlands is research conducted on the presence of toxins in grain, buckwheat and soy products. Toxins are not found and therefore is control considered unnecessary.
PatulinApergillus clavatus;
Penicillium roqueforti;
Penicillium expansum;
Penicillium patulum
Apples, apple juice, moulded fruits, grains, cheese and sausageAWI: 7 (JECFA, 1989)Acute toxic (damaging of lungs, brains, liver and kidneys); carcinogenic effects are not found (IARC, 1985).Maximum levels according to Regulation (EC) No 1881/2006At fermentation of apple juice to Cider and through vitamin C takes destruction place. The Patulin content can be an indication for the handling of GMP-guidelines (to establish that rotten apples are not used).

Chemistry: Milk and Dairy products

Chemical componentFood productLegislationComments
Dioxins: Polychlorinated dibenzodioxins (PCDDs), Polychlorinated dibenzofurans PCDF's and 2,3,7,8-Tetrachlorodibenzodioxin (TCDD).Herbs (through Feed) and , (especially fatty fish such as herring and salmon) and Vegetables, Oils/fats, dairy and eggsMaximum levels according to Regulation (EC) No 1881/2006Formed from chlorinated linkages during heating with low oxygen levels. Carcinogenic for humans and animals above a threshold level.
Polychlorinated biphenyls (PCBs) and dioxin-like PCBs (dl-PCBs)Herbs (through Feed) poultry, fish (especially fatty fish such as herring and salmon), Vegetables, Oils/fats, dairy and eggsMaximum levels according to Regulation (EC) No 1881/2006Carcinogenic for animals and humans. Moreover, it might induce skin disorders, reproductive toxicity and liver diseases. PCBs burn above 1200 °C, are insoluble and are applied as plasticizers, paint, ink, lacquer, glue and insecticides.
Components as a consequence of fat oxidation.herbs (products), dairy products (containing normal amounts of fat) and every other product known as a “fatty” product.Accepted, no direct consequences for public health.Fat oxidation causes off flavours of organoleptic characteristics. Through the reaction of oxygen with the formed aldehydes acetic acid, formic acid and propionic acid can be formed. This induces rancidity.
Residues: (animal)medicines, antibiotics, anti-microbial substances, growth promotors and vitamins.MeatForbidden for each drug is, a Maximum Residue Level (MRL) established with a specific accepted amount in herbs, liver, kidney, fat, milk and eggs. The usage of Chloramphenicol and nitrofuran is forbidden in the EU and VS while still accepted in some Asian countries.
