Aflatoxins are toxic metabolites found in foods and feeds. When ruminants eat foodstuffs containing aflatoxins B1 and B2, these toxins are metabolized and excreted as aflatoxin M1 and M2 in milk. The aim was to determine the incidence of these aflatoxins in commercial milk collected from supermarkets in Ribeirao Preto-SP, Brazil, and consisting of 60 ultrahigh temperature (UHT) milk samples and 79 pasteurized milk samples. The milk samples were analysed according to method 986.16 of AOAC International. None of the milk samples analysed were contaminated with aflatoxin M2, and aflatoxin M1 was detected in 29 (20.9%) of samples in the range 50-240 ng l-1. The results show that despite a high occurrence of aflatoxin M1 in commercial pasteurized and UHT milk sold in Ribeirao Preto in 1999 and 2000, the contamination level of these toxins could not be considered a serious public health problem according to MERCOSUR Technical Regulations. However, levels in 20.9% of the milk samples exceeded the concentration of 50 ng l-1 permitted by the European Union. Although it is not necessary to continue monitoring the incidence and levels of aflatoxins M1 and M2 in milk samples, surveillance could be appropriate. |
