The cancer risk estimate from ETO, ECH or EBH residues in spices is based on the estimated average consumption of individual spices multiplied by the average value for ETO, ECH and EBH residual levels found and their appropriate cancer potency factors (Table 7). The published potency value from the US EPA of 0.29 (mg/kg/day)1, and the value derived in this report from an oral exposure study, 0.55 (mg/kg/day)1 form the range of cancer risks. The more recently published value from the California EPA of 0.31 (mg/kg/day)1 falls within this range.
