Abstract:

The Authors analyzed and evaluated the contamination levels and occurrence trend of the 6 major mycotoxins in animal feed and raw materials in China in 2006 and 2007, and concluded with the following findings: ①Three mycotoxins with the most significant contamination levels and occurrence rates are zearalenone, fumonisin and vomitocxin, which are all field mycotoxins; Aflatoxin, the storage mycotoxin we paid the most attention in the history, was found with the lower contamination levels and less problematic in animal feed and raw materials in China.②Multi-mycotoxins were found existed in raw materials and complete feeds; the synergistic effects of multi-mycotoxins deteriorate the impacts of mycotoxins and severity of mycotoxicity.③The mycotoxin contamination of by-products, especially corn by-products such as DDGs and corn gluten meal, was found very serious.④Comparing to those in single energy or protein raw material, the multimycotoxin contamination levels in complete feeds are the more accurate and representative parameters. ⑤The most economical and practical approaches to control the effects of mycotoxins are quality control of raw materials and using of effective mycotoxin binders. 
