Out of 67 milk samples analyzed in the spring 1980, nine samples contained 0.05 to 0.10 microgram . 1(-1) of M1 aflatoxin. Fifty samples analyzed in the spring 1982 contained no M1 aflatoxin. The toxicity of M1 aflatoxin determined in two-, three- and four-day chick embryo amounted to 0.10 microgram, the toxicity of B1 aflatoxin to 0.014 microgram per embryo. On the basis of M1 aflatoxin content in milk and its toxicity it can be presumed that with the current fodder base for dairy cows no toxic effect of M1 aflatoxin in milk and milk products is to be expected.
