Popis: Microbiological analyses for aerobic bacteria counts and pathogens (coliforms, E. coli, S. aureus, Salmonella spp and V. cholerae) were carried out on small pelagic fish specie commonly found in Lake Victoria, dagaa (Rastrineobola argentea). The samples were obtained from various process steps within the field sun-drying and market conditions in Kisumu, Kenya. Dagaa was also oven-dried at 30oC, 40oC and 50oC after washing with selected solutions i.e. salted (3% sodium chloride), chlorinated solutions (100ppm) and potable tap water, which was used as control. Results obtained indicated that total aerobic bacterial counts in the freshly caught dagaa increased significantly (p
