Abstract Background Pesticide contamination in aquatic ecosystems due to intensive agriculture poses significant health risks communities reliant on fish as a dietary staple. In northern Ghana, where drives high pesticide use, residues from application persist water bodies. Libga and Builpela reservoirs, important for local livelihoods sources are exposed agricultural effluents. Despite their importance, limited data exist these nor have the associated surrounding been quantified. Persistent pesticides of particular concern. This study assessed human Clarias (C.) anguillaris (African catfish) Oreochromis (O.) niloticus (Nile tilapia) reservoirs which receive substantial runoff. Methods Fish samples both were analysed 42 using Liquid Chromatography-Tandem Mass Spectrometry (LC–MS/MS). Lifetime cancer risk, hazard quotient, ratio computed evaluate linked consumption. Two species fish, anguilaris , tested contamination. Results Four detected: pirimiphos-methyl, chlorpyriphos, p,p'-DDE, p,p'-DDD. exhibited higher organophosphate levels with pirimiphos-methyl: showing highest concentration at 0.05 ± 0.02 mg/kg 0.04 0.00 reservoir. showed elevated organochlorines (p,p'-DDD DDD: 0.03 0.01 mg/kg). Organochlorines dominated load (55–60%), p,p'-DDE contributing 27.9% total. The quotient indicated little adverse impacts. However, cumulative LCR values p,p'-DDD potential lifetime chronic exposure. Conclusions our study, though short-term consumption minimal non-carcinogenic risks, consuming C. O. long-term intake may elevate persistent organochlorines. Regular monitoring, public advisories, stricter regulations necessary mitigate protect vulnerable Ghana.
