Abstract

Results of a 2-year (2009-2010) survey on the occurrence of ochratoxin A (OTA) in swine feed and in feed for laying hens in Portugal are reported. A total of 664 samples (478 swine feed, 186 feed for laying hens) were analyzed by a HPLC method using fluorescence detection with 2 μg kg(-1) as detection limit. In swine feed, 31 samples (6.49%) were positive for OTA. In feed for laying hens, 12 samples (6.45%) were OTA-positive. The average levels of contamination were low, with median values of positive samples at 3-4 μg kg(-1) in both years and both commodities, although a few samples contained exceptionally high levels (maximum 130 μg kg(-1)). Only the maximum level sample (swine feed) contained OTA at a concentration exceeding the European Commission guidance value. The remaining OTA concentrations found in feed samples were much lower than the guidance values.
