摘要

目的:调查上海市市售水产品中寄生虫感染的流行情况,了解居民食源性寄生虫病的知识和做法,为食源性寄生虫病的监测和控制提供依据。方法:随机抽取2020 - 2023年上海市黄浦区、普陀区、闵行区和青浦区农贸市场、超市、零售商店和食肆的淡水产品、海水产品和腌制产品。采用挤压法、消化法和解剖法对水产品中寄生虫囊蚴和幼虫进行检测,并比较不同类型水产品中寄生虫感染的检测情况。并于2023年通过问卷调查的方式,随机抽取4区农贸市场、超市、社区街道等人口集中地区10-80岁居民对食源性寄生虫病的知识和行为进行调查,分析食源性寄生虫病知识知晓率和健康行为形成率。结果:2020 - 2023年,上海市黄埔、普陀、闵行、青浦区共检出2 109份水产品,检出寄生虫感染317份,总检出率为15.03%。在1 221份淡水产品中检出寄生虫感染8种,检出率为0.66%,以华支睾吸虫为优势寄生虫,分别在小伪螺旋体、大菱鲆和鲫鱼中检出。501种海水产品共检出寄生虫感染82种,检出率为16.37%,以异尖线虫为优势寄生虫,检出的主要品种有:细毛癣菌、多角鳞鱼、日本肺蝗、透明斑蝗、头毛癣菌、大角鳞鱼、尼松鳞鱼、银纹层蛾和沙蚤。387种腌渍产品中检出227种产品存在寄生虫感染,检出率为58.66%,白颡鱼和蟹膏中囊蚴检出率分别为76.27%(225/295)和11.11%(2/18),差异有统计学意义(χ2 = 159.511, P < 0.05)。淡水虾、蟹和腌制制品中未检出吸虫感染,淡水和海水鱼类中未检出叶状双芽绦虫幼虫感染。问卷调查显示,食源性寄生虫病知识知知率为79.00%(222/281),饭前饭后洗手、不直接饮用过滤水或自来水、不吃生的或半生的食物、愿意改变特殊饮食偏好或不良生活习惯以保持健康、愿意了解更多食源性寄生虫病知识的比例分别为99.64%(280/281)、72.24%(203/281)、56.23%(158/281)。黄浦区、普陀区、闵行区和青浦区分别占96.80%(272/281)和97.51%(274/281)。结论:上海市市售水产品存在食源性寄生虫污染。虽然居民了解食源性寄生虫病的知识,但需要对食源性寄生虫病进行可持续监测并改进健康教育,以尽量减少人类寄生虫感染的风险。

[Surveillance of parasitic infections in market-sold aquatic products and knowledge and practice towards food-borne parasitic diseases among residents in Shanghai Municipality from 2020 to 2023].

Objective: To investigate the prevalence of parasitic infections in market-sold aquatic products in Shanghai Municipality, and to understand the knowledge and practice towards food-borne parasitic diseases among residents, so as to provide insights into the surveillance and control of food-borne parasitic diseases.

Methods: Freshwater products, seawater products and pickled products were randomly obtained from agricultural trade markets, supermarkets, retail stores and restaurants in Huangpu, Putuo, Minhang and Qingpu districts of Shanghai Municipality from 2020 to 2023. Parasite metacercariae and larvae were detected in these aquatic products using pressing method, digestion method and the dissection method, and the detection of parasitic infection was compared in different types of aquatic products. In addition, the knowledge and practice towards food-borne parasitic diseases were investigated among residents aged 10-80 years old who randomly selected from agricultural trade markets, supermarkets, community streets and other population concentration areas in these four districts by questionnaire in 2023, and the awareness of food-borne parasitic diseases knowledge and percentage of healthy behaviors formation were analyzed.

Results: A total of 2 109 aquatic products sampled from Huangpu, Putuo, Minhang and Qingpu districts of Shanghai Municipality from 2020 to 2023 were detected, and there were 317 products detected with parasitic infections, with an overall detection rate of 15.03%. There were 8 products detected with parasitic infections in 1 221 freshwater products, with a detection rate of 0.66%, and Clonorchis sinensis was the predominant parasite, which was detected in Pseudorasbora parva, Rhodeus amarus and Carassius auratus. There were 82 products detected with parasitic infections in 501 seawater products, with a detection rate of 16.37%, and Anisakis was the predominant parasite, which was detected in Trichiurus lepturus, Larimichthys polyactis, Pneumatophorus japonicus, Collchthys lucidus, Mugil cephalus, Larimichthys crocea, Scomberomorus niphonius, Stromateoides argenteus and Cololabis saira. There were 227 products detected with parasitic infections in 387 pickled products, with a detection rate of 58.66%, and the prevalence rates of Echinostoma metacercariae were 76.27% (225/295) in Bullacta exarata and 11.11% (2/18) in crab pastes, respectively (χ2 = 159.511, P < 0.05). No Paragonimus infection was found in freshwater shrimps, crabs and pickled products, and no Diphyllobothrium latum larvae infection was detected in freshwater and seawater fish. Questionnaire surveys showed that the awareness of food-borne parasitic diseases knowledge was 79.00% (222/281), and the percentages of washing hands before and after meals, not drinking filtered water or tap water directly, not eating raw or semi-raw food, being willing to change special dietary preferences or bad living habits for health, and being willing to learn more about food-borne parasitic diseases knowledge were 99.64% (280/281), 72.24% (203/281), 56.23% (158/281), 96.80% (272/281) and 97.51%(274/281) among residents living in Huangpu, Putuo, Minhang and Qingpu districts, respectively.

Conclusions: There are food-borne parasite contaminations in market-sold aquatic products in Shanghai Municipality. Although residents are aware of food-borne parasitic diseases knowledge, sustainable surveillance of food-borne parasitic diseases and improved health education are required to minimize the risk of human parasitic infections.
