冰鲜肉鸡制品中食源性致病菌污染的调查

Survey on Contamination Status of Food-borne Pathogens in Chilled Broilers

目的通过调查84份冰鲜鸡肉、鸡腿、鸡翅中的几种食源性致病菌,了解冰鲜肉鸡制品中食源性致病菌的污染情况,为控制污染提供科学依据。方法随机抽取市场上的84份冰鲜鸡肉、鸡腿、鸡翅,检测其中的沙门菌、志贺菌、李斯特菌、金黄色葡萄球菌、致泻性大肠埃希菌等几种常见食源性致病菌。结果 84份样品中共检出沙门菌8株,检出率为9.52%、李斯特菌17株,检出率为20.24%、金黄色葡萄球菌45株,检出率为53.57%、O157H7型大肠埃希菌1株,检出率为1.19%。结论市售冰鲜肉鸡制品中食源性致病菌污染严重,特别是金黄色葡萄球菌污染率非常高,迫切需要加强对肉鸡的屠宰、加工、进出口等各环节进行检疫。

Objective To study the contamination status of food- borne pathogens in chilled broilers （chicken, drumstick, and chicken wing）, and to provide a scientific basis for control of food - borne pathogens. Methods Foodborne pathogens such as Salmonella, Shigella, Listeria, Staphylococcus aureus, Escherichia coli were detected in 84 randomly selected samples, including chilled chicken, chilled drumstick, and chilled chicken wing. Results Eight strains of Salmonel- la, 17 strains of Listerias, 45 St@bylococcus aureus, 1 O1571-17 Escherichia coli were detected in 84 samples, with the detection rates of 9.52%, 20.24%, 53.57%, and 1.19%, respectively. Conclusions The contamination of food - borne pathogens in chilled broilers is very serious, especially the contamination of Staphylococcus aureus. Quarantine inspection must be strengthened in broiler slaughter, further processing, import and export of chilled broilers, and other links.
