Anisakiasis is a gastrointestinal fish-borne zoonosis caused by the ingestion of third stage larvae of the genus . Between January and December 2013, 1112 specimens of four commercial fish species (, , and ) marketed in Sardinia (Italy) were examined for sp. The overall prevalence of spp larvae was 39.9%, all morphologically identified as Type I showed the highest prevalence (100%), followed by (Atlantic 91.0%, Mediterranean 71.2%), (32.7%) and (25.9%). All the larvae found in Mediterranean hosts were genetically identified as , whereas 90.0% of the larvae found in the Atlantic belonged to and 10.0% to . The mean abundance of sp. larvae was positively correlated with fish size in , Atlantic and local . The prevalence of infection was greater in the body cavity (37.9%) than in the edible muscle (9.4%). However, 1.8% of the examined fish were infected exclusively in the muscle. Therefore, the risk associated to the consumption of raw or undercooked fishery products poses the need of measures such as visual inspection and preventive treatments to guarantee consumers' health.
异尖线虫病是一种食源性胃肠人畜共患病，由摄入异尖线虫属的第三期幼虫引起。2013年1月至12月，对意大利撒丁岛市场上销售的四种商业鱼类（、、和）的1112个样本进行了异尖线虫属物种检测。异尖线虫属幼虫的总体患病率为39.9%，所有形态学鉴定为I型的患病率最高（100%），其次是（大西洋91.0%，地中海71.2%）、（32.7%）和（25.9%）。在地中海宿主中发现的所有幼虫经基因鉴定为，而在大西洋中发现的幼虫90.0%属于，10.0%属于。异尖线虫属幼虫的平均丰度与、大西洋和当地的鱼体大小呈正相关。体腔感染率（37.9%）高于可食用肌肉感染率（9.4%）。然而，1.8%的受检鱼类仅肌肉感染。因此，食用生的或未煮熟的渔业产品带来的风险表明需要采取诸如目视检查和预防性处理等措施来保障消费者健康。
