Occurrence of Aflatoxin M₁ in cow milk in El Salvador: Results from a two-year survey.

ABSTRACT: Aflatoxin M₁ (AFM₁) is a metabolite of Aflatoxin B₁ (AFB₁) and is excreted through cow´s milk. AFM₁ contamination of milk is extended geographically and there might be seasons-related variations for both prevalence and contents, with higher than average values in regions with long periods of drought like El Salvador. Therefore, this project quantified AFM₁ levels in raw cow milk and AFs in cattle feedstuffs, during the transitional dry-rainy seasons of two consecutive years and it determined the variation of occurrence and contents associated to drought. Significant variations were shown from year to year in the prevalence of contamination (30% vs. 20%) and in the average levels of AFM₁ in milk (0.056 vs 0.039 μg/
