Abstract
This study reports the fungal load of smoked African catfish (Clarias gariepinus) obtained from Dugbe, Aleshinloye, Bodija, and Sango markets in the Ibadan metropolis. Fungal loads were determined using standard microbiological procedures. The fungi isolated were Rhizopus, Aspergillus, Fusarium, and Penicillium species. Fish samples from the Bodija market had significantly (p<0.05) higher fungal load compared with those from other markets under study. This study indicated that smoked catfish sold in the various markets in Ibadan is best for consumption as the microbial load still falls within acceptable limits for human consumption.
