title: Occurrence of aflatoxins in layer feed and corn samples in Konya province, Turkey.
abstract: The natural occurrence of aflatoxin was investigated in layer feed and corn samples brought to Konya Veterinary Control and Research Institute Laboratory between 15 April and 15 December 2002. Seventy-eight samples (52 feeds, 26 corn samples) were analysed for total aflatoxin (B1 + B2 + G1 + G2) by an ELISA screening method. Aflatoxin contamination was deter-mined in 37 feed samples (71.1%) and 15 corn samples (57.7%), with a range of 1.5-133 microg kg(-1). However, a majority of the aflatoxin contamination was less than 5 microg kg(-1) (50% within the positive samples). Two feed samples and two corn samples exceeded the maximum tolerated levels in feed (20 microg kg(-1)) and feedstuffs (50 microg kg(-1)) for total flatoxin.
