摘要
目的了解市售乳粉中致病菌污染状况。方法于2013年在10个省份居民购买的主要场所如超市、网店等采集不同种类的2 735份乳粉,按照食品安全国家标准方法进行蜡样芽胞杆菌、金黄色葡萄球菌和沙门菌的检测。结果乳粉中蜡样芽胞杆菌检出率为16.78%(459/2 735),调制乳粉蜡样芽胞杆菌检出率高于全脂乳粉;金黄色葡萄球菌检出率为0.51%(14/2 735),沙门菌检出率为0.04%(1/2 735)。不同采样地点(农贸市场、超市和网店)、不同采样季度的乳粉中致病菌检出率差异均无统计学意义,第三、四季度生产的乳粉致病菌检出率高于第一、二季度。结论乳粉中存在致病菌污染,应提高对乳粉的卫生质量的重视。
Objective To investigate the contamination of pathogens in milk powders. Methods Different kinds of milk powders were sampled from main consuming places such as supermarkets ,online stores in 10 provinces in China in 2003. All the samples were detected for Bacillus cereus, Staphylococcus aureus and Salmonella with national food safety standard methods. Results In 2 735 samples, the detection rate of Bacillus cereus, Staphylococcus aureus, and Salmonella were 16. 78% ,0. 51%, and 0. 04%, respectively. The positive rate of Bacillus cereus in formulated milk powder was higher than that in whole milk powder. There were no statistically significant differences in pathogen detection rate for milk powder samples from main sampling places（ farmer＇s market, supermarket and online shop）and those collected in different seasons, althouth the pathogen detection rate for milk powder produced druing the third and forth quarter was higher than that during other quarters of a year. Conclusion There is pathogen contamination in milk powders available in retail markets and hygiene quality of milk powder still needs to be concerned.
