Toxic biogenic amnines, such as histamine & tyramine, are produced by the decarboxylation of free amino acids in any food. This can be caused by excessive consumption of amines or a deficiency of detoxifying enzymes (e.g. [[Monoamine Oxidase]]) in an individual. In the case of [[Scombroid poisoning]] Histadine in fish is converted into Histamine by [[Spoilage Bacteria - WikiVPH|spoilage bacteria]] before the fish is consumed.

This syptoms of Histamine intoxification are analygous to an allergic reaction i.e. rash, oedema & hypotension. Tyramine causes a rise in blood pressure possibly associated with migranes. Ripened cheeses, fermented sausages, red wine & chocolate are implicated as sources of tyramine poisoning.
