摘　　要：为了了解广州市市售生鲜鸡肉的微生物污染状况,并为建立食物污染及中毒的预警系统提供数据基础。2009年10月到12月从广州市天河区5个农贸市场和5个超市采集鲜鸡肉50件,对其表面进行了菌落总数、嗜冷菌数、大肠菌群、沙门氏菌、李斯特菌、金黄色葡萄球菌的定性、定量检测。结果表明,农贸市场鸡肉产品的菌落总数和大肠菌群数比超市的高;而超市鸡肉产品的嗜冷菌数要比农贸市场的高。农贸市场沙门氏菌检出率为44.0%、单增李斯特菌检出率为36.0%、金黄色葡萄球菌检出率为36.0%。超市沙门氏菌检出率为28.0%、单增李斯特菌检出率为28.0%、金黄色葡萄球菌检出率为36.0%。总体上超市的鲜鸡肉微生物污染程度比农贸市场的低。The level of microbial contamination of commercial raw chicken in Guangzhou market was determined in this survey from October to December, 2009. Fifty samples were collected from ten markets of Tianhe District, Guangzhou, and tested for a range of foodborne pathogens and indicator organisms, including the numbers of total colonies, Psychrophilic bacteria, Coliform bacteria, Salmonella, Listeria monocytogenes, and Staphylococcus aureus present on the surface of the raw chicken. The results showed that the numbers of total colonies and Coliform bacteria in the raw chicken samples from farm markets were higher than those from supermarkets, while the number of Psychrophilic bacteria in the former was lower than in the later. The detection rates of Salmonella, Listeria monocytogenes, and Staphylococcus aureus in samples from farm markets were 44.0 %, 36.0%, and 36.0%, respectively, while these in samples from supermarket were 28.0%, 28.0%, and 36.0%, respectively. In general, the level of microbial contamination of raw chicken samples from supermarkets was lower than that from farm markets.
