Abstract
Aflatoxin M1 is the 4-hydroxy derivative of aflatoxin B1 (see Fig. 1). Aflatoxin M1 appears in milk and milk products as the direct result of the intake of aflatoxin B1 -contaminated feed by dairy cows (1). The amount excreted as aflatoxin M1, as a percentage of aflatoxin B1 in feed, is usually 1-4% (2), but values as high as 6% have been reported at μg daily intake levels of aflatoxin B1(3). The carry-over of aflatoxin B1 to milk may vary largely from animal to animal, from day to day, and from one milking to the next.
Chemical structure of aflatoxin M1.
