The relation between organochlorine residues in animal feeds and residues in tissues, milk and eggs: a review

Abstract

Tolerance levels for organochlorine pesticide in stockfeed have been set by legislation in Queensland. The purpose of this review was to derive accumulation ratios from trials which have involved feeding organochlorine pesticides to cattle, poultry and pigs. These ratios can be used with the maximum residue limits already established for food products from these animals to calculate maximum permissibleresidue levels in feed. It was concluded that the levels for aldrin and dieldrin should be reduced from 0.05 to 0.01 nig/kg and that a level for benzene hexachloride, other than the y isomer, of 0.01 mg/kg be included. In all other cases where information was available the levels set by legislation are already below those calculated from trial results.
