Summary
Anisakiasis cases increased due to better diagnosis, not just sushi consumption. This parasitic infection from raw fish highlights diagnostic advancements in public health surveillance.
Area of Science:
- Parasitology
- Public Health
- Foodborne Illnesses
Background:
- Anisakiasis and codworm anisakiasis are parasitic infections caused by Anisakis sp. and Pseudoterranova decipiens.
- Larval nematodes in fish and squid muscles are transmitted to humans via raw or undercooked seafood consumption.
- The rise in sushi consumption has been implicated in the spread of these infections.
Purpose of the Study:
- To discuss the current status of anisakiasis and codworm anisakiasis.
- To investigate the reasons behind the apparent increase in human cases.
Main Methods:
- Review of epidemiological data on anisakiasis and codworm anisakiasis.
- Analysis of factors contributing to infection rates, including diagnostic capabilities and dietary trends.
Main Results:
- An apparent increase in human cases of anisakiasis and codworm anisakiasis since 1972.
- The rise in reported cases is more closely linked to improvements in diagnostic methods than to increased sushi consumption.
- Anisakis sp. and Pseudoterranova decipiens infections remain a public health concern.
Conclusions:
- Advances in diagnostic techniques have led to a greater detection of anisakiasis and codworm anisakiasis cases.
- While sushi consumption is a potential risk factor, diagnostic improvements are a primary driver of the observed increase in reported infections.
