A study on the impact of Mbeubeuss landfill on the microbiological and chemical quality of broiler chicken carcasses produced in the commune of Malika has been carried out in Dakar. It involved a sample of 100 chickens collected from nearby farms. Research on the various contaminants has been conducted in accordance with standard methods. Results show that: On the microbiological quality of samples, 98% of carcasses are contaminated by aerobic micro-organisms at 30°C (54% at a distance of less than one km and 44% at a distance of more than one km from Mbeubeuss landfill); 93% by Escherichia coli (53% and 40%); 25% by Staphylococcus aureus (18% and 7%); 94% by Clostridium perfringens (54% and 40%); 7% by Salmonella spp. (2% and 5%). Regarding the microbiological standards, 89 of the 100 chicken carcass samples studied are satisfactory. The 11 unsatisfactory carcasses include 3 with excess Escherichia coli (3 at a distance of less than 1 km), 1 with excess Staphylococcus aureus (at a distance of less than 1 km) and 7 with salmonella spp. (2 at a distance of less than 1 km and 5 at a distance of more than 1 km). As for the chemical quality of the chickens, 68% of carcasses are contaminated with Mercury (40% at a distance of less than one km and 28% at a distance of more than one km); 0% contamination with Lead and 0% contamination with Cadmium. 20% of the carcasses are deemed unsatisfactory due to mercury contamination. When the quality of drinking water is taken into account in the variation of microbiological and chemical quality of broiler chickens, all the samples deemed unsatisfactory are coming from farms where the well is the source of drinking water for birds.
