摘 要：
为了解广西部分地区生鲜畜禽肉中食源性致病菌污染状况,对广西南宁、贵港、梧州、贺州4个市2015年-2016年具有代表性的超市和市场销售的生鲜畜禽肉随机采集2 326份,按照我国食品国家安全标准GB 4789系列标准进行沙门菌、金黄色葡萄球菌、单增李斯特菌、霍乱弧菌、副溶血性弧菌、大肠埃希菌O157:H7的检测.结果显示,2 326份样品中共检出致病菌1 178株,检出率为50.64%.其中沙门菌、金黄色葡萄球菌、副溶血性弧菌、霍乱弧菌、单增李斯特菌的检出率分别为27.94%(650/2 326)、16.51%(384/2 326)、2.75%(64/2 326)、1.98%(46/2 326)、1.46%(34/2 326),未检出大肠埃希菌O157∶H7.猪肉、牛肉、鸡肉、鸭肉样品中致病菌检出率分别为43.80%(654/1 493)、46.90%(106/226)、77.13%(290/376)、55.41%(128/231),四者差异显著(P<0.05).超市和市场样品中致病菌检出率分别为58.26%(388/666)、47.59%(790/1 660),两者差异显著(P<0.05).4个市样品中致病菌检出率分别为南宁市70.56%(326/462)、贵港市56.47%(314/556)、贺州市43.62%(325/745)、梧州市37.83%(213/563),四者差异显著(P<0.05).结果表明,所监测的4个地区生鲜畜禽肉受致病菌污染严重,以沙门菌和金黄色葡萄球菌为主,相关部门应加大对畜禽肉类监管力度,确保消费者的食肉安全.

摘 要：
To investigate and indentify the contamination of food-borne pathogens in raw livestock and poultry meats in part of GuangXi from 2015 to 2016,2 326 samples were collected from supermarkets and markets in 4 cities of Guangxi(Nanning,Guigang,Wuzhou and Hezhou),and supposed to analyze 6 kinds of food-borne pathogens,including Salmonella,Staphylococcus aureus,Listeria monocytogenes,Vibrio cholerae,Vibrio parahaemolyticus,Escherichia coli O157:H7 according to our national food safety stands of GB 4789.The result showed that totally 1 178 strains of food-borne pathogens were detected in the 2 326 samples,with the detection rate of 50.64%.The detection rates of Salmonella,Staphylococcus arureus,Vibrio parahaemolyticus,Vibrio cholerae,Listeria monocytogenes were 27.94%(650/2 326),16.51%(384/2 326),2.75%(64/2 326),1.98%(46/2 326)and 1.46%(34/2 326)respectively,Escherichia coli O157:H7 were not detected.The detection rates of pork,beef,chickens,ducks were 43.80%(654/1493),46.90%(106/226),77.13%(290/376)and 55.41%(128/231)respectively.There were statistically significant differences in the 4 rates(P<0.05).The detection rates of supermarkets and the markets were 58.26%(388/666)and 47.59%(790/1 660).There were statistically significant differences in the 2 rates(P<0.05).The detection rates in Nanning,Guigang,Hezhou,Wuzhou were 70.56%(326/462),56.47%(314/556),43.62%(325/745)and 37.83%(213/563)respectively.There were statistically significant differences in the 4 rates(P<0.05).Thus,the contamination of raw livestock and poultry meats by bacterial pathogens was severe in the 4 cities of Guangxi,in which were mainly contaminated by Salmonella,Staphylococcus aureus.Therefore,preventive measures should be strengthened to ensure the food quality and health of consumers.
