Résumé

The authors have previously isolated psychrophilic histamine (Hm)-producing bacteria from fresh fish at low temperatures. Among these were strains that produce high levels of Hm even under low temperatures. In this study, they inoculated 2 strains of psychrophilic Hm-producing bacteria into swordfish (10^4 cfu/g), and examined their behavior during storage at low temperatures (4, 10, and 15°C). The average counts of normal viable bacteria and Hm-producing bacteria, and cumulative Hm levels in the fish were measured over time and analyzed. We detected Hm levels of 300 mg/kg or more in 5 days, and 800 mg/kg or more in 7 days, during storage at 4°C. At 10°C, the authors detected Hm levels of more than 150 mg/kg in 3 days, while at 15°C, they detected Hm production of =200 mg/kg after 36 h. These data indicate that Hm accumulates in fresh fish during storage at low temperatures when psychrophilic Hm-producing bacteria are present. Further, they observe that inadequate storage temperatures cause the accumulation of Hm within a short time. [Reprinted with permission from Elsevier. Copyright, 2012].
