2015—2018年12种植物性饲料原料中黄曲霉毒素B1污染状况调查分析

Investigation and analysis of aflatoxin B1 contamination in 12 plant feed materials from 2015 to 2018

采集了2015-2018年间的12种植物性饲料原料的183份样品,采用液相色谱-质谱法定性和高效液相色谱法定量的方法,对黄曲霉毒素B1的污染状况进行检测分析,按照《饲料卫生标准》GB 13078-2017进行判定。结果表明,其中11种原料40份样品检出污染,5种原料18份样品超标,黄曲霉毒素B1污染率高,每年的超标率上升趋势明显。植物性饲料原料生产企业、饲料产品生产企业及养殖业对黄曲霉毒素B1的污染控制应加以重视,以确保饲料产品的安全。

183 samples of 12 plant feedstuff from 2015 to 2018 were collected,and the contamination of aflatoxin B 1 was detected and analyzed by LC-MS and HPLC.The results showed that 40 samples of 11 kinds of feedstuff were contaminated,18 samples of 5 kinds of feedstuff exceeded the standard, aflatoxin B 1 contamination rate was high,the annual exceeding rate increased significantly.The pollution control of aflatoxin B 1 should be paid more attention to by plant feedstuff production enterprises,feed production enterprises and aquaculture industry to ensure the safety of feed products.
