Milk samples from individual farms were collected in three seasons. The average concentration of AFM 1 in milk samples collected in winter (0.089 ± 0.034 μg/L) was significantly higher than those in rainy season (0.071 ± 0.028 μg/L) and summer (0.050 ± 0.021 μg/L). The present study suggests that regulatory limits for AFM 1 are needed to regulate and ensure the quality of raw milk and milk products in Thailand. © 2010 Springer Science+Business Media, LLC.Mahidol UniversityEnvironmental SciencePharmacology, Toxicology and PharmaceuticsArticleSCOPUS10.1007/s00128-010-0056-3
