Popis: Pesticides are routinely applied by cocoa farmers to enhance cocoa production, which is threatened by pest infestations and diseases. However, the undesired health implications of pesticide applications on the farmers are yet to be fully elucidated especially among cocoa farmers in Idanre despite being the hub of cocoa production in Southwestern Nigeria. This study assessed the extent of pesticide use by cocoa farmers in the study area and determined the effects of exposure on their health using haematological and biochemical parameters as indices. A cross-sectional survey comprising 150 cocoa farmers and 50 controls (artisans) was carried out using structured questionnaire. Blood samples were obtained from participants for the determination of copper and sulphate levels, haematological (haematocrit, red blood cell counts, white blood cell counts and platelet counts) and biochemical (creatinine, cholesterol, direct bilirubin and total bilirubin) parameters. The blood levels of copper and sulphate were significantly higher in the cocoa farmers than in the controls. However, there was no significant difference between the subjects and controls for most of the haematological and biochemical parameters except for the platelet counts and total bilirubin levels. The data from the study did not suggest any serious health effects due to pesticide exposure on the cocoa farmers despite the high blood levels of copper and sulphate, probably due to exposure to copper-based fungicides. However, the high serum bilirubin level among the subjects was an indication of possible liver damage. As such, cocoa farmers should be guided against indiscriminate use of pesticides on their farms.
