Genotoxicological Safety of Gamma Irradiated Salted and Fermented Shrimp
초록
Gamma irradiation at 20 kGy was apploed to salted and fermented shrimps to evaluate its possible genotoxicity. The genotoxicity of irradiated salted and fermented shrimps was evaluated by Salmonella typhimurium reversion assay, chromosomal aberration test and in vivo micronucleus assay. The results were negative in the bacterial reversion assay with S. typhimurium TA98, TA100. No mutagenicity was detected in the assay both with and without metabolic activation. In chromosomal aberration tests with CHL cells and in vivo mouse micronucleus assay, no significant difference in the incidences of chromosomal aberration and micronuclei was observed between nonirradiated and 20 kGy-irradiated salted and fermented shrimps. These results indicate that salted and fermented shrimps irradiated at 20 kGy did not show any genotoxic effects under these experimental conditions.
