Aflatoxin M1 and cyclopiazonic acid were determined in 48
samples of grade A-C and ultra-high-temperature (UHT)-treated
fluid commercial milk from São Paulo, Brazil, from July to
December 2004. Aflatoxin M1 and cyclopiazonic acid (CPA)
determinations were carried out by HPLC. Results showed 37
(77.1%) positive samples for Aflatoxin M1 at levels of
0.011-0.251 microg l(-1) milk, which were below the tolerance
limit for Aflatoxin M1 in milk as adopted by Brazilian
regulations. Mean levels of Aflatoxin M1 in grades A-C and
UHT milk were 0.060+/-0.080, 0.056+/-0.063, 0.064+/-0.041 and
0.075+/-0.048microg l(-1), respectively. cyclopiazonic acid
(CPA) was detected in two samples (4.2%) of grade A milk at
levels of 6.4 and 9.7 microg l(-1). This is the first report of
the occurrence of cyclopiazonic acid (CPA) in milk in Brazil. It
was concluded that the incidence of Aflatoxin M1 in milk
traded in São Paulo is low, but the simultaneous occurrence of
cyclopiazonic acid (CPA), even at low levels, warrants concern
about Aflatoxin M1 in milk and milk products.
