北京地区被检饲料及饲料原料黄曲霉毒素污染情况的调查
Investigation on Contamination Situation of Aflatoxin in Detected Feeds and Feedstuffs in Beijing Area
摘要
Abstract
[Objective] This study was conducted to analyze and evaluate the contamination situation of aflatoxin in feeds and feedstuffs in Beijing area. [Method] Atotal of 187 feed samples from 21 farms in Beijing were sampled to detect and quantify the content of aflatoxin (B1, B2, G1 and G2). An efficient HPLC with post-column photochemical derivatization method was developed, including immunoaffinity step for aflatoxin extraction from feeds and feedstuffs followed by liquid chromatography (LC) for quantification. [Result] Results showed that the detection rate of AFB1 in corn, bran, soybean meal, DDGS, swine and poultry complete feeds was 50.0%, 46.2%, 33.3%, 94.1%, 67.1% and 94.3%, the over standard rate was 6.2%, 0.0%, 0.0%, 5.9%, 6.6% and 0.0%, and the average content was 5.98, 0.25, 1.00, 9.83, 2.89 and 1.06 μg·kg-1, respectively. [Conclusion] These results indicated that the average content of aflatoxin in complete feeds, corn and DDGS were the highest. Aflatoxin contamination was widely found in both feeds and feedstuffs.关键词
