ABSTRACT
We investigated the effect of storage time and temperature on muscular histamine (HIS) contents in little tunny (LT). Fifty LT were preserved at various temperatures (0- 21°C). We collected muscles from several areas at 0-, 6-, 12-, 18-, and 24 h post-fishing for further examination. Throughout storage time and temperature, there was a significant increase in fish deterioration, HIS levels, and HFB count in abdominal > tail > dorsal muscle. Vitek2 gave 99% confidence identity of the highly histaminergic strains Lelliottia amnigena-1 and Acinetobacter haemolyticus. There was a positive correlation between HIS levels, HFB counts, and microscopic lesion scores during storage.
