Crayfish
Crayfish may carry histamine from bacterial activity after catch, and freshness is the most important factor in managing risk.
Crayfish carries a primary concern around freshness — shellfish break down quickly once out of the water, and bacterial activity can rapidly produce histamine.
-
Post-catch spoilage — shellfish begin accumulating histamine quickly after catch due to bacterial activity, which is why freshness is so important with crayfish
-
Preparation method — pre-cooked, stored, or frozen crayfish tends to carry more risk than freshly cooked live crayfish, where the histamine accumulation window is much shorter
Freshly cooked, live-to-pot crayfish is generally the lower-risk option compared to pre-cooked or frozen versions.
