Mutagenicities of N-nitrosamines on Salmonella.
TL;DR: The mutagenic activities of 11 N-nitrosamines were tested using Salmonella typhimurium TA100 and TA98 with a drug-activating system from the rat liver, whereas N,N-diphenylnitrosamine, a non-carcinogen, was not Mutagenic.
Journal ArticleDOI
Heterocyclic amines: Mutagens/carcinogens produced during cooking of meat and fish.
TL;DR: Avoidance of exposure to HCAs or reduction of HCAs’biological effects as far as possible are to be highly recommended, and usage of microwave ovens for cooking and supplementation of the diet, for example with soy‐isoflavones, which have been found to suppress the occurrence of HCA‐induced breast cancers, should be encouraged.
Journal Article
Food-derived Mutagens and Carcinogens
TL;DR: It is suggested that even very low doses of heterocyclic amines form DNA adducts and may be implicated in the development of human cancer under conditions in which many other mutagens-carcinogens, tumor promoters, and factors stimulating cancer progression exist.
Journal ArticleDOI
Mutagenicity of carcinogenic azo dyes and their derivatives

TL;DR: It is suggested that the carcinogenic effects of azo dyes may involve modification of DNA in the case of Salmonella typhimurium.
Journal ArticleDOI
Mutagenicities of smoke condensates and the charred surface of fish and meat.
TL;DR: Smoke condensates obtained from broiling fish showed mutagenic activity for Salmonella typhimurium TA100 and TA98 and Extracts of the charred surface of broiled fish and meat also containedmutagenic substances.
