Histamine production in scrombrotoxin poisoning occurs via which process?

Explanation:
Histamine production in scombroid poisoning happens when bacteria on spoiled fish produce an enzyme called histidine decarboxylase, which converts the amino acid histidine into histamine. This decarboxylation step is what builds up histamine levels in the fish tissue, and the resulting histamine is heat-stable, so cooking doesn’t eliminate it. The other listed processes—oxidizing glycine, hydrolyzing lactose, or dehydrating tyrosine—do not generate histamine in this context. So the bacterial decarboxylation of histidine is the correct explanation.
