Listeria monocytogenes in Food Safety

The occurrence of aflatoxins M1 (AFLAM1) and B1 (AFLAB1) was evaluated in 112 milk samples (whole, skimmed, semi-skimmed—liquids and powders), collected at a local commercial establishment in southern Brazil and Assomada City, Cape Verde. AFLAM1 and AFLAB1 were determined by using high-performance liquid chromatography with fluorescence detection. For the 62 milk samples from 41 supermarkets in the city of Rio Grande, Rio Grande do Sul, 68% were contaminated by AFLAM1 (range, 40–3670 ng L−1) and 16% were contaminated by AFLAB1 (range, 40–600 ng L−1), with contamination found only in liquid milk. Among the 50 samples from Assomada City, AFLAM1 was detected in 76% of the samples (range, 32–2896 ng L−1), at values below the current Brazilian legislation for the maximum permitted level in milk powder (5000 ng L−1) but higher than that recommended by the European Commission.
