Frog legs
Fresh frog legs are low in histamine, but they're highly perishable and need to be very fresh.
Frog legs are a fresh protein that doesn't naturally contain significant histamine.
-
Perishability is the main concern — like other delicate proteins such as fish and shellfish, frog legs spoil quickly, and histamine can build up fast if they're not kept very cold and consumed soon after harvest
-
Preparation matters — restaurant or market frog legs of unknown freshness carry more uncertainty than those you can verify are fresh or properly frozen
When you can confirm they're fresh or flash-frozen, frog legs are generally a low-concern protein option.
