Abstract
AbstractData regarding ochratoxin A (OTA) and zearalenone (ZEA) contamination in feed in South China are limited. Here, we evaluated OTA and ZEA contamination in 514 poultry feed samples collected from South China. We validated a modified QuEChERS (quick, easy, cheap, effective, rugged, and safe) method and the mycotoxins were quantified by high‐pressure liquid chromatography–tandem mass spectrometry. OTA and ZEA were detected in 2.92% and 100% of the feed samples, respectively. Furthermore, 0%, 0.68%, and 7.0% of Hainan, Guangdong, and Guangxi feed samples were contaminated with OTA, at mean concentrations of 0.00, 1.14, and 0.88 μg/kg, respectively. All samples were contaminated with ZEA, and the mean concentrations were 2094.1, 14.3, and 8.73 μg/kg in the samples from Hainan, Guangdong, and Guangxi, respectively. The findings of this study indicate the strong need for intense monitoring of mycotoxin, especially ZEA, contamination in feed.
