: Nematodes are only dangerous if consumed alive, which can lead to Anisakidosis (abdominal pain, nausea). The smoking process used for salmon usually involves temperatures or freezing stages that neutralize the larvae.
: Because the parasites were dead, some manufacturers argued they were still within legal limits. K-Tipp countered that consumers pay for fish, not "fish plus parasites," regardless of their biological state. How to Protect Yourself
In a 2022 quality test that left many consumers reeling, the Swiss consumer magazine (often referred to as KO-TEST in various regions) conducted a rigorous lab analysis of smoked salmon products sold in major supermarkets. The results were stomach-churning: researchers discovered nematodes (roundworms) lurking in several popular brands. The Findings: Worms in the Fillet
