Application of the margin of exposure (MoE) approach to substances in food that are genotoxic and carcinogenic: Example: Methyleugenol, CASRN: 93-15-2

The weight of evidence points to weak genotoxic activity of methyleugenol, the putative genotoxic carcinogen being 1′-sulphate ester metabolite. Dose response modelling of the data for methyleugenol gave a BMDL10 for male rat liver adenoma or carcinoma (combined) of 7.9 mg/kg-bw/d following adjustment to daily average doses. The MoEs ranged from 100 to 800 depending on the assumptions used in the exposure estimation.
