目的了解海宁市2007年-2012年食物中毒案例中致病菌污染情况,为发生食物中毒事件时采样、检验和预防提供参考,为卫生监督和监测提供科学依据。方法对中毒事件中的各个环节进行采样,采用GB 4789.10-2010和食源性致病菌监测网络的统一方法进行检测。结果在6年49起食物中毒事件中,共检出致病菌41起,致病菌的检出率为83.6%,副溶血性弧菌检出率最高为42.9%,依次为沙门菌和金黄色葡萄球菌,占12.4%和8.2%,志贺菌和大肠埃希菌O157∶H7检出率相同,为6.1%,溶血性链球菌和单增李斯特菌检出率最低,为4.1%。食物中毒主要发生在第二、三季度,占总发生率的46.9%和34.7%。在49起食物中毒事件中,农村、乡镇发生40起,城区发生9起。结论海宁市的食物中毒以副溶血性弧菌为主,主要发生于第二、三季度,农村高于城市,应加强卫生监督和相应技术指导,减少此类食物中毒事件的发生。
Objective To understand the pathogen contamination in food poisoning cases from 2007 to 2012 in Haining City, provide reference for sampling, testing and prevention in the event of food poisoning, and provide a scientific basis for health supervision and monitoring. Methods The poisoning events in all aspects of sampling, using GB 4789.10-2010 and foodborne pathogenic bacteria monitoring network unified method for testing. Results Among 49 cases of food poisoning in 6 years, 41 pathogens were detected, the positive rate of pathogenic bacteria was 83.6% and the highest rate of Vibrio parahaemolyticus was 42.9%, followed by Salmonella and gold Staphylococcus aureus accounted for 12.4% and 8.2% respectively. The detection rates of Shigella and Escherichia coli O157: H7 were the same at 6.1%. The detection rate of hemolytic streptococcus and Listeria monocytogenes was the lowest at 4.1%. Food poisoning mainly occurred in the second and third quarters, accounting for 46.9% and 34.7% of the total. In 49 cases of food poisoning, there were 40 rural areas and townships and 9 urban areas. Conclusion The food poisoning in Haining City is mainly Vibrio parahaemolyticus, which occurs mainly in the second and third quarters. The rural areas are higher than the urban areas. Health supervision and corresponding technical guidance should be strengthened to reduce the occurrence of such food poisoning incidents.
