AI Article Synopsis
- Researchers examined the risk of anisakiasis from ready-to-eat (RTE) mackerel products in Japan by studying 448 samples from 2019 to 2021.
- They found that 54% of the samples contained Anisakis larvae, with 36% having live larvae, totaling 3,170 larvae isolated.
- The majority were identified as A. simplex, with specific regions showing lower prevalence, and there were seasonal peaks in larvae occurrence, particularly in spring.
Article Abstract
The risk of contracting anisakiasis from consuming ready-to-eat (RTE) mackerel products in Japan was investigated by examining the prevalence and abundance of Anisakis simplex and its sibling species in these products. From 2019 to 2021, a total of 448 RTE mackerel products were purchased in Japan. Anisakis larvae were isolated from 244 of the 448 samples (54 %), and live larvae were isolated from 161 of the 448 samples (36 %). In total, 3170 Anisakis larvae, which included 919 live larvae, were isolated. The isolated Anisakis larvae consisted of 3118 A. simplex (s. s.), 27 A. pegreffii, and 25 hybrid genotype (A. simplex [s. s.] × A. pegreffii) larvae. No A. berlandi larvae were isolated. The prevalence of larvae in samples of mackerel caught in the Southern Japan region and Sea of Japan was much lower than that in mackerel caught in other areas. Both the prevalence of Anisakis larvae in all samples and their abundance in larvae-positive samples exhibited specific seasonal variations, being high in spring.
