All US government pesticide residue datasets show that persistent organochlorine (OC) insecticide residues are surprisingly common in certain foods despite being off the market for over 20 years. Residues of dieldrin, in particular, pose substantial risks in certain root crops. About 60% of the samples of organic vegetables found to contain pesticides are contaminated with OCs. Government regulators, organic certifiers, and the food industry will face growing pressure to develop methods to identify OC contaminated fields and avoid production of crops prone to assimilating OC residues in harvested foodstuffs.
An attempt has been made to assess daily intake of of dieldrin with fish and fishery products in Poland. The calculated arithmetic mean weighted concentration of dieldrin in muscle tissue of the fatty Baltic fish was 20 ng/g wet weight (n = 3863) in 1970-1983 and 4.4 ng/g wet weight in 1986-1992 (n = 143) while in lean fish was 6.7 ng/g wet weight (n = 9210 in 1970-1983 and 1.5 ng/g wet weight (n = 143) in 1986-1992. The intake of dieldrin has been assessed for 230 to 300 ng/person/day (mean 270 ng) in years 1970-1985 and from 44 to 54 ng/person/day (mean 51 ng) in 1989-1996.
