The Giant Anisakis Scandal—The Reality Indicated by "Wriggling White Threads" in Autumn Salmon: The Latest Situation in Japan and Abroad, Correct Identification and Countermeasures

An article titled "Massive Anisakis Found in Supermarket Autumn Salmon" was distributed on September 16 and quickly spread across social media, leading to a flurry of bewildered reactions such as "Seeing this makes me lose my appetite." Anisakis is a parasitic nematode that can be found in fish such as mackerel, saury, salmon, and squid. If ingested alive, it can cause sudden abdominal pain and vomiting. However, it can be killed by heating (60°C for one minute) or proper freezing (such as -20°C for over 24 hours), and it is often possible to remove it by visual inspection. In Japan, there are established categories for "raw consumption" and "for cooking," along with visual inspections and HACCP standards. Similarly, international bodies like the US CDC and the UK FSA have set freezing standards and inspection guidelines. Interest in this issue has been growing internationally, with videos of "worms wriggling in raw salmon" going viral on platforms like TikTok in recent years. Consumers are advised to focus on labeling, freshness, and proper cooking methods, and to respond calmly without excessive fear.
