Anchovy
Fresh anchovies are already prone to rapid histamine buildup — they are considered high-risk by most sensitivity frameworks even when fresh, and need to be eaten as soon as possible after catch.
Anchovies are small, oily fish that deteriorate quickly, and histamine starts accumulating soon after they're caught.
-
Fast histamine accumulation — anchovies have a high histidine content and are readily colonised by histamine-producing bacteria; histamine can rise to significant levels within hours at room temperature, and most sensitivity frameworks rate fresh anchovy as high-risk even under good handling conditions
-
Compared to canned anchovy — fresh anchovy is considerably lower in histamine than cured or canned versions, but is still considered high-risk in most references; freshness is everything here
If you're buying fresh anchovies, same-day from a trusted fishmonger is the safest bet.
