Aflatoxin M1 is the product of aflatoxin B1 transformation in the digestive apparatus of dairy animals. Once these animals are fed with B1 contaminated feed, liver enzymes transform it into aflatoxin M1. This toxin is found then in milk and dairy products and, even if less toxic than its precursor, is still mutagenic and carcinogenic. Due to aflatoxin M1 toxicity and the likelihood of its presence in milk and dairy products, the level of this toxin is strictly regulated from European and International laws.
In the EU, the maximum tolerated level of aflatoxin M1 is 0.05 parts per billion (ppb), and a lower limit of 0.025 ppb is envisaged for so called baby-foods. In the US, the Food and Drug Administration (FDA) established a maximum level for aflatoxin M1 of 0.5 ppb; China –with GB 2761-2011- and the International CODEX ALIMENTARIUS adopted the same limit as well.
Tecna presents here its portfolio of products dedicated to aflatoxin M1 screening in milk and dairy products. In order to fulfill international regulations new kits for extra EU markets have been recently introduced.
