This study was conducted to determine the prevalence of gastrointestinal parasites in domestic chickens using the abattoir of Mack's farm Osara, Kogi state between January and March 2022. A total of 200 (100 exotic and 100 local breeds with 50 males and 50 females each) faecal samples from the gastro-intestinal tracts of already slaughtered chicken were examined from January to March 2022 using formol-ether concentration technique for the presence of gastrointestinal parasites. Microscopic method was employed for morphological identification of parasite isolates. The result showed that of the 200 samples examined, 178 (89%) were found to be infected with one or more parasites. A higher infection rate of 90 (90%) was found in the local breed than in exotic breed 88(88%). The helminths species found were, Ascaridia galli 66(33.67%), Heterakis gallinarum 44(22.44%), Capillaria Spp 30(15.30%), Gongylonema ingluvocola 20(10.20%), Strongyloides avium 6(3.06%), Raillietina echinobrothrida 6(3.06%), Tricuris tricura 10(5.10%), Choanotaenia infundibulum 10(5.10%) and Coccidian spp 4(2.04%) while the gastrointestinal protozoan isolated was Coccidian spp 4(2.04%).
 Conclusion: An insignificant difference in parasite prevalence (p >0.05) exists between exotic and local chicken, suggesting potential consumer exposure to infection through cross-infection. This study highlights the risk associated with consuming chicken from poorly managed poultry systems and establishes the need for policymaking toward improved poultry production.
