Abstract

Aflatoxins are a major threat to human health because it causes mutations in DNA and weakens the immune response. The body is inserted through the food of animal origin (milk and dairy products) and plant origin and inhalation of contaminated air. There are 4 types of aflatoxins (B-1, B-2, G-1, G-2), of which the most dangerous is B-1, which is metabolized in the liver to the carcinogen metabolite M-1. Aflatoxins are heat stable and are not eliminated by pasteurization. Because of these characteristics, regular checkups are necessary in order to prevent contamination of raw materials and food. The specific objective of the analysis was to confirm the usefulness of the mycotoxin absorbing agents, as food supplements in dairy cows, in minimization of aflatoxin levels in raw milk. For that purpose, all bulk tank milk from different lines in Pelagonia region were tested using ELISA method. When the first test showed data suggesting the presence of contamination with aflatoxins, the second check for individual farmers was done and with the proven contamination, the addition of Mycosorb, as a mycotoxin absorbing agents, to the feed was recommended to reduce the amount of aflatoxins. The data were collected for 3 consecutive years, from Pelagonia region. The contamination of the bulk tank milk during the years was distributed unequally, with the greater predominance of the autumn and winter, when more corn silage was used as an animal feed. The maximum contamination was observed during 2013 (November) of 1.03 μg.kg-1, and for the rest of the time, the highest contamination level for specific sectors was around 0.6μg. kg-1. After the use of Mycosorb, the level of Aflatoxin M in the milk was reduced below the acceptable limit of 0.05 μg.kg-1. According to the results obtained during this study, we can conclude that the use of Mycosorb can significantly help in regulation of the level of aflatoxin M1 in raw milk without impairing the quality and safety of milk as a raw material in the dairy industry. Key words: aflatoxins, milk and dairy products, Mycosorb
