Evaluations

Evaluation year: 1997

ADI:
0-0.7 mg/kg bw

Intake:
1998, TRS 891-JECFA 51/132,159; FAS 42-JECFA 51/453. Intake estimates based on food additive levels in the draft General Standard for Food Additives being developed by the Codex Committee on Food Additives and Contaminants, integrated with national data on food consumption, exceeded the ADI of 0-0.7 mg/kg bw for mean intake for the three Member States that submitted such data. In national data submitted by four Member States, estimates of mean intake of TBHQ did not exceed the ADI. The potential exists for consumers of high levels of TBHQ to exceed the ADI, but the available data were insufficient to estimate the number of such consumers or the magnitude and duration of intake above the ADI.
