Background & Objective: Histamine poisoning which is induced from seafood is
the most common disease around the world. Determining the amount of histamine in
canned tuna fish shows not only the healthy quality of fish, but also it is
effective in protecting the health and safety of the consumers.
Materials & Methods: In this cross-sectional study, 60 samples of histamine
content canned tuna fish marketed in supermarkets of Tabriz city was analyzed through ELISA
method. Histamine levels in the samples were compared based on the time between
the production and the production seasonwith limited range. Statistical analysis
was performed using SPSS software version 16.
Results: Histamine levels between 5-200.3 mg/kg were different.
Histamine levelin canned food was 30 % lower and 70% higher than the
permissible limit (50 mg kg) in some cans. Histamine levels in canned tuna
produced in North and South regions were statistically significant
(p<0.05).Canned tuna fish produced in summer and autumn, respectively, had
the highest and lowest levels of histamine.
Conclusion: According to high percentage of canned tuna, which
have histamine more than permissible limit, the risk of histamine toxicity is
