title: A survey of residues of oganochlorine pesticides in hen eggs in Uganda.
abstract: One hundred hen eggs were analysed by gas chromatography for the presence of residues of organochlorine pesticides. Sixty one eggs were collected from free-range hens in Tororo county in Tororo district and 39 eggs from enclosed hens (commercial layers) in the outskirts of Kampala city in Uganda. Residues of 9 organochroline compounds were detected in the hen eggs in the following frequencies: p,p'-DDE (100%), p,p'-DDT (85%), lindane (13%), dieldrin (11%), o,p'-DDT (10%), p,p'-DDD (8%), HCB (7%), &-HCH (4%), and o,p'-DDD (1%). All the mean residue levels were below the respective EEC MRL and FAO/WHO ERL. Only 3 (3%) samples contained total DDT levels above the EEC MRL and FAO ERL of 0.1mg /kg fresh weight. The residue levels of other organochlroine compounds in individual samples were below both the EEC MRL and the FAO/WHO ERL. It was concluded that contamination of hen eggs with residues of organochlorine pesticides from areas In Uganda that were considered In this study presents a low health risk to the consumers, and that organochlorine residue levels in hen eggs in Uganda were relatively lower than those reported from other African countries.
