Sardines (smoked)
Smoked sardines combine one of the highest-histamine fish with a preservation process that adds even more accumulation time.
Sardines convert histidine to histamine extremely quickly after catch — and the smoking process involves curing or brining stages that extend the window for that conversion.
-
Compounding risk — by the time a sardine is smoked and packaged, it has had significantly more time to accumulate histamine than a fresh sardine cooked the same day
-
Smoked vs. canned — both are very high risk, but smoked sardines often have a longer shelf life, meaning they may be stored longer before consumption
Among preserved fish options, smoked sardines tend to sit at the higher end of histamine content consistently.
