Human exposure to aflatoxins in Zimbabwe.

In this communication, we report the detection of aflatoxins in human urine and breast milk. The 2553 urine samples were collected from donors of different ages and sexes at centres throughout Zimbabwe, while 54 breast milk samples were collected from breast feeding mothers. The most predominant aflatoxins found were AFM and AFG. The national average of urine samples contaminated was 6.0 percent. There were, however, some areas in which the extent of contamination was 34 percent. Of the 54 breast milk samples collected, 11 percent were contaminated mainly with AFM.
