“…This could as well account for the high blood levels of sulphate among the cocoa farmers. Although copper is an essential element in living organisms including man, playing significant role as a component of important metabolizing enzymes such as Cu/Zn superoxide dismutase, immunity enhancement and collagen formation (Li et al, 2021; Monteith and Skaar, 2021; Yue et al, 2022); however, it is potentially toxic at elevated levels resulting in physiological dysfunctions such an iono- and osmo-regulatory impairment (Adeyemi et al, 2022) and diseases like Hodgkin’s lymphoma (Cunzhi et al, 2001), brain tumours (Florianczyk et al, 2003) and chronic renal failure (Panichi et al, 2004). Similarly, elevated blood sulphate levels have been implicated in adverse health conditions such as diarrhea and ulcerative colitis (Magee et al, 2000).…”

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.

“…The parameters that were determined included haematocrit or packed cell volume (PCV), red blood cell (RBC) count, white blood cell (WBC) count and platelet count. The haematological parameters were determined following the procedures of Adeyemi et al (2022). Haematocrit was determined using the microhaematocrit method.…”

The presence of pathogenic bacteria is a problem that might be present in farmed shrimp due to exposure in the environment or post‐harvest handling. Retail farmed shrimp in Bangladesh (Penaeus monodon and Macrobrachium rosenbergii) were tested for common pathogenic bacteria namely Salmonella, L. monocytogenes, Vibrio spp., and E. coli. None of these bacteria were found and instead Enterobacter cloacae, Escherichia fergusonii, Proteus penneri, Klebsiella aerogenes, Enterococcus faecalis, Serratia marcescens, Citrobacter freundii, and Aeromonas dhakensis were detected. Pathogenic bacteria found in Bangladeshi shrimp may be due to the farm environment, poor handling during harvest or post‐harvest, or unhygienic market conditions. The results indicate that retail shrimp from Bangladesh have food safety concerns. Proper laws and policies need to be enforced and implemented to ensure food safety related to fish and shrimp.
