Description
Beatriz Mendes and colleagues map a food safety hazard in fish sold from Portuguese waters, in a 2026 epidemiological study. Larvae of Anisakis worms live in marine fish and can infect people who eat them raw or undercooked. The team examined 538 fish of five commercial species from six coastal localities, comparing winter and summer catches in 2024 to find where and when the risk runs highest.
Every species carried larvae, mostly in the guts, with a smaller share in the flesh people eat. Horse mackerel showed the heaviest infections. Genetic testing named Anisakis pegreffii as the dominant species, and a northern, winter-leaning pattern appeared for its close relative in muscle tissue. The authors stress strict freezing, cooking, and handling after capture to protect consumers.
