Squid
Squid accumulates histamine rapidly after catch — freshness is the single biggest factor in how much it contains.
Like most seafood, squid doesn't start out high in histamine — it gets that way fast once out of the water.
-
Freshness matters enormously — bacteria on seafood convert amino acids into histamine quickly at room temperature, so even a short break in the cold chain can spike levels significantly
-
Cooking doesn't help — once histamine forms in fish or squid, heat won't break it down, so freshness before cooking is what counts
If you're shopping for squid, buying from a trusted fishmonger and cooking it the same day tends to make a real difference.
