Abstract:
To evaluate the risk of anisakiasis, we investigated their prevalence in fillets of chub mackerel and blue mackerel in 2022 and 2023. The results indicated that the prevalence (percent of larvae-positive fillet samples) and abundance (number of larvae per 100 g fillet) of Anisakis larvae in fillets of chub mackerel were not significantly different between the Sea of Japan and the Pacific Ocean. The prevalence and abundance of Anisakis larvae in blue mackerel were markedly lower than those in the chub mackerel.
