A method for an enzymatic assay of histamine by using histamine oxidase from Arthrobacter globiformis in combination with amperometric determination of H2O2 is described. Histamine could be quantified at a level as low as 10(-7) M. The assay is adaptable to determine histamine in food samples including tuna fish with good sensitivity and selectivity.
