Abstract
Gamma irradiation at 30 kGy was applied to porridge to evaluate its possible genotoxicity. The genotoxicity of irradiated porridge 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, TA1535 and TA1537. 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 30 kGy-irradiated porridge. These results indicate that porridge irradiated at 30 kGy did not show any genotoxic effects under these experimental conditions.
