Although histamine is relevant from standpoint of Scombroid poisoining (and
even there the dose-response relationship suggests a more complicated
mechanism than histamine alone) - as an indicator of decomposition,
histamine does not always correlate well with sensory assessment.
Among the biogenic amines sometimes cadaverine and putrescine are reasonable
indicators but even these compounds are not infallible.
