background aflatoxins are a group of very toxic compounds produced by a fungal species and are found in food products. aflatoxin m1 (afm1) is a type found in dairy products and resistant to pasteurization. afm1 can adversely affect hepatocytes in human and leading to various liver diseases. thus, it is essential to examine raw milk for the presence of afm1. conclusions according to the results ...

During 2002 and 2003, a total of 107 samples of raw, pasteurized and ultrahigh treated temperature (UHT) milk commercialized in the cities of São Paulo and Marília (SP) were analyzed for the presence of aflatoxin M1 (AFM1). AFM1 was detected in 79 (73.8%) of milk samples, ranging from <0.02 to 0.26 μg/L.The samples were analyzed using an immunoaffinity column for cleanup and a thin layer chroma...

Aflatoxins (AF) are a group of toxic secondary metabolites mostly produced by strains Aspergillus spp. fungi. There several types aflatoxins (AFB1, AFG1, AFB2, AFG2, AFM1, AFM2, etc.), but the most and common is AFB1. have been shown to possess powerful carcinogenic, mutagenic teratogenic properties. AFB1 can contaminate feed food during growth and/or storage under inappropriate conditions. Whe...
