Abstract: Objective To understand the situation of Anisakis infection of in market?available marine fish in Dongtai City, so as to provide the evidence for the assessment of the risk of human Anisakis infections. Methods Raw and fresh marine fish caught in the sea of Dongtai City for sale were collected in 2018. The fish were weighted and dissected for the identification of Anisakis, and the prevalence and intensity of Anisakis infections were calculated. In addition, the correlation between the weight of Anisakis?infected marine fish and the infection intensity of Anisakis was examined. Results There were four species of marine fish infected with Anisakis, including Trichiurus haumela, Scomberomorus niphonius, Pneumatophorus japonicus and Larimichthys polyactis. Among the 149 fish samples, there were 78 with Anisakis infections, with a prevalence rate of 52.35%. The prevalence of Anisakis infection was 100.00% (28/28), 30.00% (9/30), 0 (0/30), 53.33% (16/30) and 80.65% (25/31) in T. haumela, S. niphonius, cuttle fish, P. japonicus and L. polyactis, respectively. A total of 1 049 Anisakis worms were collected, and the overall intensity of infection was 13.45 worms per fish. Spearman correlation analysis showed a positive correlation between the weight of T. haumela and the intensity of Anisakis infection (rs = 0.38, P = 0.047), and no correlation was found in other fish species. Conclusions There is a high rate of Anisakis infection in marine fish along the offshore areas of Dongtai City. Intensification of health education is required and healthy and safe dietary habits are encouranged.

摘要: 目的 掌握东台市市售海鱼中异尖线虫感染现状,为评估人群异尖线虫感染风险提供依据。方法 于2018年采集东台市海域捕捞且在当地销售的未经加工的新鲜海鱼,称重后解剖检测异尖线虫(含包囊)。计算海鱼异尖线虫感染率和感染度,分析异尖线虫感染海鱼质量和异尖线虫感染度间的相关性。结果 采集的5种海鱼中有4种(带鱼、马鲛鱼、鲐鱼、小黄鱼)检出异尖线虫。累计采集的149尾海鱼样本中,78尾感染异尖线虫,总感染率为52.35%,带鱼、马鲛鱼、墨鱼、鲐鱼、小黄鱼感染率分别为100.00%(28/28)、30.00%(9/30)、0(0/30)、53.33%(16/30)、80.65%(25/31)。共检出异尖线虫1 049条,总感染强度为13.45条/尾。Spearman秩相关检验显示,带鱼质量与异尖线虫感染度成正相关(rs = 0.38,P = 0.047);其他鱼类质量和异尖线虫感染度无相关性。结论 东台市近海海域鱼类存在较高异尖线虫感染率,应进一步加大宣传教育力度,倡导市民养成健康安全的饮食习惯。
