A study was conducted to evaluate the occurrence of ochratoxin A (OTA) in complete poultry feeds (n--0) and poultry feed ingredients (n--86) from Pakistan. All samples were first analyzed by indirect enzyme linked immunosorbent assay (ELISA), samples with OTA concentrations above the European Union maximum regulatory limit (MRL, 100?μg/kg) were further confirmed by HPLC-FLD. Contamination frequency and mean OTA levels were 31?% and 51?μg/kg in feed ingredients, and the corresponding values for complete feeds were 38?% and 75?μg/kg. Ten samples of complete poultry feed and 19 samples of feed ingredients contained OTA at levels higher than the MRL. The results of the present study indicate that there is a strong need for a more intense monitoring programs for OTA in poultry feed.
