Histamine Tracker
Prawns
Prawns accumulate histamine quickly after catch due to rapid bacterial activity, making freshness especially important.
Prawns break down fast, and histamine builds up with each hour they're not on ice or being processed — bacterial conversion of histidine to histamine happens rapidly in shellfish.
-
Rapid deterioration — prawns are among the seafood types most prone to quick histamine accumulation; even when they look and smell fine, levels can already be elevated
-
Bacterial formation is the driver — the high histamine levels in shellfish like prawns come from bacterial activity during handling and storage, which is why the cold chain matters so much
The freshest prawns you can find, cooked and eaten right away, tend to be the gentler option.
