Ferric maltol positive in Ames; maltol positive in Ames and in vivo mouse micronucleus assay
“Ferric maltol was mutagenic in vitro in bacterial reverse mutation (Ames) assays. Ferric maltol increased revertant frequency in the absence and presence of metabolic activation. Fertility studies have not been conducted with ferric maltol. Maltol was mutagenic in the Ames assay and increased micronuclei in an in vivo clastogenicity assay in mice.”

Carcinogenicity
Maltol (complex component) not carcinogenic in 18-month mouse and 2-year rat studies up to 400 mg/kg
“Maltol was not carcinogenic in a 18-month study in mice at doses up to 400 mg/kg (approximately 5.6 times the human daily dose). Maltol was not carcinogenic in a 2-year study in rats at doses up to 400 mg/kg (approximately 11.2 times the human daily dose).”
Maltol multigeneration rat study: no effects on mating, fertility or early embryonic development up to 400 mg/kg/day
“In a multi-generation animal reproduction study in male and female rats, there were no effects on mating, fertility, or early embryonic development at doses up to 400 mg/kg/day (approximately 11.2 times the human daily dose).”
Not genotoxic overall: Ames negative; in vitro chromosome aberration positive without (not with) metabolic activation; rat micronucleus and comet negative
