The annual joint meeting of experts from the Food and Agriculture Organisation and the World Health Organisation was held in September 2001. This purpose of this meeting was to: review data analysis methods for estimating the maximum residue levels arising from pesticide use according to good agricultural practices; and review toxicological and related data for estimating acceptable daily intakes (ADIs) of pesticides for human health. This report presents information on ADIs of a number of pesticides, maximum residue levels, and general principles for the evaluation of pesticides. It provides summaries of the toxicological evaluations of pesticide residues in food, together with the recommendations made by the joint meeting.
