A Study of Contamination of T-2 Toxin,Ochratoxin A and Fumonisin in Feed Ingredients and Compound Feed in China
The purpose of this study was to investigate the individual and combined contamination situation of T-2 toxin,ochratoxin A(OTA)and fumonisin(FUM)in feed ingredients and compound feed in China.The T-2 toxin,OTA and FUM contents were measured in 474,385 and 1 905 feed ingredients and compound feed samples collected from different regions of China,respectively.The results showed that the total contamination rates of T-2 toxin,OTA and FUM in feed ingredients and compound feed were 26.8％,61.8％and 59.3％,respectively,and their content mean values were 0 to 45.8 µg/kg,0.3 to 11.1 μg/kg and 0 to 16.3 mg/kg re-spectively.Notably,the proportions of feed ingredients and compound feed with T-2 toxin,OTA and FUM contents exceeding Chinese Hygienical Standard for Feeds were 0.4％,0.3％and 0.5％,respectively.Moreo-ver,over 60％feed ingredients and compound feed were co-contaminated with mycotoxins,and the co-con-tamination rate ranged from 30.3％to 88.9％.In conclusion,the contamination situation of T-2 toxin,OTA and FUM in feed ingredients and compound feed in China is more serious,so it is particularly important to strengthen the monitoring of the contamination of the above-mentioned mycotoxins in livestock and poultry feed in China and the implementation of relevant preventive measures during production.[Chinese Journal of Ani-mal Nutrition,2024,36(4):2690-2698]
