Histamine production by Enterobacter aerogenes in chub mackerel (Scomber japonicus) at various storage temperatures
Abstract Growth of Enterobacter aerogenes and accumulation of histamine in chub mackerel (Scomber japonicus) were investigated through measuring bacterial count, histidine decarboxylase (HDC) activity and histamine content in fish samples stored at various temperatures from 4 to 37 °C.
