Pesticide residues in foodstuffs in Great Britain: Organochlorine residues in imported cereals, nuts, pulses and animal foodstuffs

Results are presented for the determination of organochlorine insecticide residues in imported cereals, nuts, pulses and animal foodstuffs for the 2 year period July 1969 to June 1971. BHC was found in all but four of the 248 samples examined but only in 25 (10%) did the level exceed 0.5 mg/kg. DDT was found in 39% of the samples of which three samples of wheat contained more than 1 mg/kg and two samples of cottonseed cake more than 0.5 mg/kg. The other commodities sampled had less than 0.2 mg/kg. DDE was detected in trace amounts in 26 % of the samples examined.
