DISTRIBUTION OF AFLATOXIN-PRODUCING MOLDS AND AFLATOXINS IN DAIRY-CATTLE FEED AND RAW-MILK

Distribution of aflatoxigenic moulds and aflatoxin B1 in Yugoslav dair y cattle feeds as well as the presence of anatoxin B1 and M1 in raw mi lk, was tested. The experiments were carried out through three years ( in all seasons). Samples were taken from state and private farms in Vo jvodina. Feeds were contaminated in 83-100% with moulds. Fungi of Aspe rgillus flavus-oryzae group were present permanently and the highest i ncidence of them was noticed during the third research year. Aflatoxin B1 was not found in the first year, but malt spent grains used for co ws' feeding in summer of the second research year was contaminated wit h it (50.0 mug/kg). The same feed and pelleted sugar beet pulp were co ntaminated with aflatoxin B1 in winter, spring and summer of the third research year (5.0 to 16.0 mug/kg). Aflatoxin B1 and M1 were not foun d in raw milk through three-years investigations.
