Setting acceptance levels of contaminants
1992
Black, Al
Acceptable levels of chemical contaminants in food are best established through joint consideration of two distinct sets of data: toxicology data on the contaminant which usually establishes a threshold for its toxicity and analytical data on the level of contaminant that occurs in the foodstuff or food. Reconciliation of these two independent data sets, together with the use of an appropriately conservative safety factor, provides a basis for the estimation of a level of contamination acceptable from a food safety perspective. Monitoring of the food supply provides information on the degree of compliance and, indirectly, the appropriateness of the contamination levels so set. Monitoring data can also be used to establish pragmatic levels of contamination in those situations where toxicological data are inadequate.
