摘要:

目的 了解云南省市售淡水产品中食源性寄生虫的感染情况,为制定食源性寄生虫病的防控策略提供依据。方法 2017—2022年,在云南省16个州(市)开展市售淡水产品食源性寄生虫感染情况监测工作,其中淡水鱼检测项目为东方次睾吸虫囊蚴、颚口线虫Ⅲ期幼虫和华支睾吸虫囊蚴,淡水螺检测项目为广州管圆线虫Ⅲ期幼虫,淡水蟹和淡水虾检测项目为并殖吸虫囊蚴。采集的样本涉及流通、餐饮和养殖环节。检测方法均采用消化法。结果 2017—2022年共检测淡水产品2 803份,检出寄生虫158份,检出率为5.64%;其中检测淡水鱼类8种共328份、淡水虾1种共57份,均未检出寄生虫;检测淡水螺3种共2 215份,广州管圆线虫Ⅲ期幼虫总检出率为5.82%;检测淡水蟹4种共203份,并殖吸虫囊蚴总检出率为14.29%。2017—2022年,云南省淡水产品寄生虫逐年检出率分别为7.69%(15/195)、8.85%(56/633)、6.01%(27/449)、2.95%(19/645)、2.78%(9/324)和5.75%(32/557)。除怒江州外,各地送检的淡水产品均检出寄生虫。不同采样环节中,流通、餐饮和养殖环节淡水产品寄生虫检出率分别为6.02%(144/2 394)、4.03%(11/273)和2.21%(3/136)。结论 云南省大部分地区市售淡水产品均存在寄生虫感染情况,应加强食品安全监管和宣教工作,提高群众自我防范意识,以减少食源性寄生虫病的发生。

Abstract:

Objective To investigate the statuses of foodborne parasites infection in freshwater products and raw meat in Yunnan Province for evidence in formulating prevention and control strategies for foodborne parasitic diseases. Methods From 2017 to 2022, the surveillance of food-borne parasitic infections in commercially available freshwater products was carried out in 16 prefectures (cities) of Yunnan Province. The freshwater fish detection project was the metacercaria of Metorchis orientali, the stage Ⅲ larvae of Gnathostoma, Clonorchis sinensis, the freshwater snail detection project was the stage Ⅲ larvae of Angiostrongylodes cantonensis, and the freshwater crab and freshwater shrimp detection project was the metacercaria of Paragonimus. The samples were collected from intermediate links, catering services and aquaculture. Digestion method was used for the detection. Results From 2017 to 2022, a total of 2 803 freshwater product samples were detected, in which parasites were detected in 158 (5.64%), yet no parasites were found in the 328 samples of 8 species of freshwater fish and 57 samples of 1 species of freshwater shrimp. The larvae were detected in 2 215 of 3 species of freshwater snails. The total detection rate of Angiostrongylus cantonensis stage Ⅲ was 5.82%. A total of 203 samples from 4 species of freshwater crab were detected, and the detection rate of Paragonimus cysticercus was 14.29%. The annual parasite detection rates of freshwater products in Yunnan Province from 2017 to 2022 were 7.69% (15/195), 8.85% (56/633), 6.01% (27/449), 2.95% (19/645), 2.78% (9/324) and 5.75% (32/557), respectively. Apart from Nujiang Prefecture, all the fresh water products sent for inspection were found to be infected with parasites. The parasite detection rates were 6.02% (144/2 394), 4.03% (11/273) and 2.21% (3/136) in circulation, catering and aquaculture, respectively. Conclusion Fresh water products were infected with parasites in some areas of Yunnan Province. The findings suggest that food hygiene supervision and education should be strengthened, and self-prevention awareness should be raised in mass to reduce the incidence of food-borne parasitic diseases.
