• Aflatoxin M-1
• Powder milk
• HPLC

Aflatoxin M-1 (AFM(1)), the main monohydroxylated of aflatoxin B-1 (AFB(1)) formed in liver and excreted in the milk, has toxicological proprieties comparable to those of AFB(1), albeit a lower carcinogenic potency. The presence of AFM(1) was investigated in 30 samples of powdered milk purchased in Argentina and Brazil. The samples were analyzed using an immunoaffinity column for cleanup and HPLC-FLD for determining AFM(1). The quantification limit was 0.1 mu g/kg. AFM(1) was found in all the samples at levels ranging from 0.1 to 0.92 mu g kg(-1) with average concentration of 0.39 mu g kg(-1).
