Occurrence of aflatoxin M1 in raw milk

Mycotoxins, as secondary products of fungi, can contaminate feeds and enter the milk through the metabolic pathway in the cow's body. The most studied mycotoxin associated with milk contamination is aflatoxin M1 (AFM1). The review focuses on the identification of different types of mycotoxins and their transfer to milk, and attention is paid to a summary of the results of monitoring aflatoxins in milk and the negative effects of mycotoxins on health and the possibility of mycotoxins determination. The practical part of the thesis consists of two subchapters, namely monitoring AFM1 in raw milk of cows, sheep and goats in the years 2006-2020 from the data of the State Veterinary Administration of the Czech Republic, where the factor of the observed period and type of milk was evaluated for AFM1 content in raw milk. The second part interprets the results of AFM1 monitoring in purchased raw cow's milk delivered to the dairy factory
