Nairobi, Murang’a record Kenya’s highest fruit chemical levels – study flags mangoes, tomatoes
Murang’a and Nairobi have emerged as the counties with the highest chemical levels in fruits tested in a new Kenyan study, raising questions about the safety of produce reaching consumers. The research, conducted by Kenya Methodist University researchers, found that Murang’a recorded the highest average chemical level at 163.95, followed by Nairobi at 153.21. Kirinyaga […]
Murang'a and Nairobi counties recorded the highest levels of chemicals in fruits tested in a new Kenyan study. The research, conducted by Kenyan university researchers, found Murang'a had the highest average chemical level at 163.95, followed by Nairobi at 153.21. Kirinyaga came in third at 146.1, while Meru had the lowest level at 109.67.
The study analyzed 392 samples of bananas, mangoes, and tomatoes collected in those four counties, alongside interviews with 180 people. The findings, published in the International Journal of Professional Practice in 2026, reveal that chemical use, weather changes, and market pressures can impact food safety. Murang'a and Nairobi had the highest chemical concentrations, reflecting intense trading and the need to quickly move fruits through the supply chain.
The study raises concerns about mangoes and tomatoes, as arsenic was found in about 8% of mango samples, exceeding acceptable contamination limits in 20% of cases. Bananas had the highest contamination rate at about 40%, with 26% of all fruit samples containing contaminants above acceptable limits. The researchers recommend stronger food safety inspections, mobile testing laboratories, improved storage and transportation, and safer ripening methods to reduce reliance on harmful chemicals.
Better training for farmers and traders and increased cooperation between authorities are also suggested.
