Salmon

Study type not stated

• Open question

  Heart and blood health⁵

  Farmed salmon fed more plant-based feed had less omega-3, and few studies test how that affects people.

Found in some samples or products

These come from where it was grown, how it was processed or cooked, or what it was made into. They are not about the ingredient itself, so the signal does not count them.

• Tapeworm infection from fish²

  In one case, a person in France got a tapeworm from eating Pacific salmon imported from Canada.

• DNA damage from food³

  In three healthy men, eating fried salmon made their urine mutagenic, but eating parsley with it lowered that.

• Food poisoning from cold fish⁴

  Boiled salmon left to cool slowly grew a germ that made people sick in five outbreaks.

• Tapeworm risk in raw fish⁶

  A tapeworm larva was found in wild pink salmon from Alaska, so raw salmon may carry it.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted.
