Abstract
A histamine concentration level of a fish item is determined by illuminating the fish and analyzing the resulting spectral image data. Specifically, an algorithm is applied to the fish image data so that a histamine concentration value is calculated for every pixel of the fish image. A corresponding histamine concentration image of the fish is produced based on the collective histamine concentration values. The fish is accepted or rejected based on the collective histamine concentration values and/or the histamine concentration image. The histamine concentration image may be used to identify specific parts of a fish fillet that exceed (or do not exceed) a predetermined histamine concentration level.
