| Abstract: | The toxic and mutagenic effects of gamma-irradiated peanut meal contaminated with aflatoxin B1 were studied in Salmonella typhimu-rium strain TM 677, using forward mutation to 8-azaguanine resistance. After treatment with 5 to 10 M-rad gamma radiation, the contaminated peanut meal lost its toxic and mutagenic properties. Irradiation at 0.1 to 1.0 M-rad removed 75–100% of the toxicity but not mutagenicity. |
