Aflatoxin M-1 (AFM(1)) was determined in 75 samples of ultra-high-temperature (UHT)-treated fluid commercial milk from Minas Gerais, Brazil, from July to November 2009. AFM(1) determinations were carried Out by HPLC. Results showed that 23 (30.7%) positive samples for AFM(1) at levels of 1000-4100 ng L-1, which were above the tolerance limit for AFM(1) in milk as adopted by Brazilian regulations. It was concluded that the incidence of AFM(1) in milk marketed in Minas Gerais state is higher, warrants concern about AFM(1) in milk and milk products. (C) 2012 Published by Elsevier Ltd.
