Abstract：
Anisakiasis is a gastrointestinal disease caused by infection with anisakid nematodes. Anisakis larvae have been listed as distinct food poisoning agents in the manual of Food Poisoning Statistics, Japan since 2013. The reported numbers of food poisoning cases caused by Anisakis larvae are gradually increasing. A total of 94.0% of the causative larvae species were identified as Anisakis simplex sensu stricto (A. simplex), and 4.4% were identified as Anisakis pegreffii, among human-isolated anisakid nematodes examined in Tokyo Metropolitan Institute of Public Health, Japan from 2011 to 2018. Anisakis species infecting fishes in Japanese waters differ depending on their habitat and depth. A. simplex mainly infects fishes in the Pacific side of Japan, and A. pegreffii mainly infects fishes in the East China Sea and Sea of Japan sides. Regarding the causative foods of anisakiasis, cases by ingestion of mackerel (Scomber spp.) have been the most common in Japan, and cases caused by eating \"marinated mackerel\" accounted for 32.8% of the total in Tokyo from 2011 to 2017. However, the number of reports of food poisoning caused by skipjack tuna (Katsuwonus pelamis) was highest in May 2018 in Japan. A parasitological surveys of Anisakis third-stage larvae in skipjack tuna in Japanese waters were conducted in 2018 and 2019, and it was confirmed that more A. simplex infections of skipjack tuna may have occurred in 2018 than usual due to the meandering flow of the Black Current. Moreover, a portion of A. simplex larvae migrated from visceral organs to the ventral muscle in live skipjack tuna before capture, suggesting that an extensive cold chain after capture cannot prevent anisakiasis. In fish species that were reported to be high frequency of causative food of anisakiasis, it is necessary to freeze or at least remove the ventral muscle.
摘要：
茴香病是由anisakid线虫感染引起的胃肠道疾病。异见幼虫已在《食物中毒统计手册》中被列为不同的食物中毒剂，自2013年以来，日本。据报道，由Anisakis幼虫引起的食物中毒病例正在逐渐增加。总共有94.0％的致病幼虫被鉴定为单纯性异象（A.单工)，4.4%的人被确定为阿尼萨基斯·佩格雷菲，在东京都公共卫生研究所检查的人类分离的anisakid线虫中，日本从2011年到2018年。在日本水域中感染鱼类的异语树物种因其栖息地和深度而异。单纯性主要感染日本太平洋一侧的鱼类，A.pegreffii主要感染东海和日本海的鱼类。关于茴香病的致病食物，通过摄入鲭鱼（粉鱼属。)在日本是最常见的，2011年至2017年，由食用“腌鱼”引起的病例占东京总数的32.8%。然而,2018年5月,日本由金枪鱼(Katsuwonuspelamis)引起的食物中毒报告数量最高.在2018年和2019年对日本水域的skip鱼金枪鱼中的Anisakis第三期幼虫进行了寄生虫学调查，并证实，由于黑流的蜿蜒流动，2018年可能比平常发生了更多的skip鱼金枪鱼单纯形感染。此外，一部分单纯性A.幼虫从内脏器官迁移到腹侧肌肉在捕获前的活金枪鱼，这表明捕获后广泛的冷链不能预防anisakiasis。据报道，在鱼种中，这种鱼种的发病率很高，有必要冷冻或至少去除腹肌。
