Between 1996 and 1998, 580 litres of milk in Mexico were surveyed for aflatoxin B1 (AFB1) and its metabolite aflatoxicol (AFL), which are mutagenic and carcinogenic mycotoxins that interconvert AFB1-AFL-AFB1. The seven most consumed brands from different regions of Mexico included pasteurized and ultrapasteurized milk with four different fat levels: whole fat (28-33 g l-1), half-skimmed (10-20 g l-1), light (1-4 g l-1) and with vegetable oil (33 g l-1). Aflatoxins in each sample were concentrated with total aflatoxin immunoaffinity columns and quantitated by high-performance liquid chromatography. A milk sample was considered contaminated if it contained ≥0.05 μg l-1 AFL. Pasteurization and ultrapasteurization of milk did not control contamination with AFL, which was present in 13% of samples at ≥0.05 μg l-1 and in 8% at ≥0.5 μg l-1, with a range of AFL from 0 to 12.4 μg l-1. AFB1 was present mainly in traces (0-0.4 μg l-1). The safest milk in relation to AFL contamination was imported milk powder with vegetable oil. There was a significant correlation between contamination of milk with AFL and the autumn (p<0.0002); the fat content was not significant. |
