[Analysis of aflatoxin Ml in fresh milk].

Seventy-seven samples of cow's milk were examined by the method after Stubble-field (1979) for the presence fo aflatoxin M1; 34 of these samples came directly from farms and 43 were mixed, being taken from tank trucks. Aflatoxin M1 was found in five samples from farms and in none of the mixed samples. In the positive cases, concentrations were determined semiquantitatively and were found to range from a trace amount up to 0.38 microgram aflatoxin M1 per litre of milk. Hence the aflatoxin M1 concentration levels never exceeded tha admissible limit value.
