摘  要：
研究旨在了解生物饲料添加剂中微生物污染情况。随机抽取生产及使用环节的微生态制剂、酶制剂及标示有微生物成分或酶制剂成分的混合型饲料添加剂产品270批,依据现行标准规定的方法进行了沙门氏菌、志贺氏菌、金黄色葡萄球菌、大肠菌群、霉菌总数、蜡样芽孢杆菌等微生物指标的检测。结果表明,生物饲料添加剂中沙门氏菌的检出率为1.85%;大肠菌群的检出率为23.33%,超标率为21.11%,检出水平为<10～10~5CFU/g;霉菌的检出率为42.22%,超标率为8.89%,检出水平为<10～10~6CFU/g;蜡样芽孢杆菌检出率为39.56%,超标率为4.44%,检出水平为<10～10~7CFU/g。结果显示,生物饲料添加剂中存在一定程度的微生物污染情况,有必要对该类产品进行质量监控。

摘  要：
This experiment was conducted to evaluate the microbial contamination in biological feed additives. 270 batches of microbial feed additives, feed enzyme preparations and mixed feed additive products labeled with microbial ingredients or enzyme ingredients in the production and use stages were randomly selected. The common pathogenic bacteria, coliform bacteria, molds count, Bacillus cereus were detected according to the methods specified in the current standards. The results showed that the detection rate of Salmonella was 1.85% in all analyzed samples; The detection rate of coliform bacteria was 23.33%, the over-standard rate was 21.11%, and the concentration within<10～10~5 CFU/g;The detection rate of mold was 42.22%, the over-standard rate was 8.89%, and the concentration within<10～10~6 CFU/g; The detection rate of B. cereus was 39.56%, the over-standard rate was 4.44%, and the concentration within<10～10~7 CFU/g. These results indicated that it is necessary to monitor the microbial contamination in biological feed additives.
