Histamine Tracker
Swordfish
Swordfish is a large, dense fish that can accumulate moderate histamine levels, especially when not kept at strict cold-chain temperatures.
Swordfish is a firm, meaty fish that takes longer to spoil than smaller oily fish — but its size means it often passes through more handling steps, giving histamine more time to develop.
-
Cold-chain sensitivity — any break in refrigeration during the journey from sea to plate allows bacterial activity and histamine formation to ramp up
-
Compared to smaller fish — swordfish doesn't accumulate histamine as rapidly as sardines or tuna, but its large cuts mean the interior may not be as consistently chilled
Buying from a reputable fishmonger and cooking it the same day is the most practical way to keep histamine levels on the lower end.
