DAIRY SAFETY

& AUTHENTICITY

Milk is picked up from a dairy farm every day, and tested on a constant basis to comply with legislation designed to protect consumers against the presence of antibiotics or mycotoxins. On the other hand, protected designations of origin (PDO) dairy products like Feta or Mozzarella must be routinely checked to ensure worldwide consumers avoid health issues related to cow milk allergies.

ProGnosis Biotech currently provides both ELISA testing kits and the novel Symmetric Technology for mycotoxin safety testing in dairy products, validated by landers Research Institute for Agriculture, Fisheries and Food (ILVO). Nonetheless, our company continues to evolve the dairy testing portfolio meeting the strict quality demands of the market for antibiotic safety and dairy authenticity.

AFLATOXIN M1

Aflatoxins are toxic metabolites of major concern to the dairy industry, generally produced by Aspergillus flavus, A. parasiticus and A. nomius. They can have immunosuppressive, mutagenic, teratogenic, and carcinogenic effects. 

Aflatoxins that are ingested by animals in contaminated pellets and forage are biotransformed at the hepatic level into Aflatoxin M1 . 

Aflatoxin is then excreted in this form into the milk used for human consumption and, it is also present in dairy products. Aflatoxin M1 in milk and milk products is considered to pose certain hygienic risks for human health and as a result, there is an established EU limit of 0,05 μg/kg (50 ppt) and 0.025 μg/kg (25 ppt) for infant food.

MILK ADULTERATION

Higher priced milk with limited seasonal availability is commonly and fraudulently adulterated with lower milk price from different dairy animals like cow. Adulterated milk either used in direct human consumption or in cheese manufacture (like feta, which is recognized as Protected Designation of Origin, PDO) results in a final product inferior to that expected by the consumer. Due to unknown milk mixtures, significant changes may occur in the final sensory characteristics and quality.

In addition, Cow’s milk allergy (CMA) is one of the most common food allergies, while Goat’s milk is also associated with a rare allergy disorder. Therefore, cow or goat milk must be declared as ingredients on food labels.

Milk adulteration can be detected by toilsome methods such as chromatography and electrophoresis requiring though highly sophisticated and expensive equipment and consequently are considered of limited value for the usual screening of milk.
