Thiaminase in Atherina boyeri

[Stefan-A]

Do any of you guys know if the sand smelt Atherina boyeri contain the enzyme thiaminase? Or smelt in general?

I feed my Thamnophis this species of fish but I can't find out if this fish is safe.

As a precaution I heat the fish in the oven at 50-80 degrees for 5 minutes.

Thanks

I suspect they do. The fish should also be heated to at least 80 C for 5 minutes, to destroy thiaminase

These fish aren't technically smelt (as in belonging to Osmeridae).
