Fish Quality Survey: Staphylococcus Aureus And Salmonella Spp Occurrence In Nile Tilapia At Informal Markets Of Nairobi

Abstract

The quality of fish sourced from Kenya has been a problem both locally and internationally. Things worsened when it was realized that some fishermen were using chemicals to fish coupled with unhygienic handling and inadequate storage facilities. This study was carried out to analyze the microbial hazards during the retailing of Nile tilapia (Oreochromis niloticus) at Kibera, Kawangware and Korokocho markets. The work was carried out for a period of three months (December, 2002 to February, 2003). Results of this study showed fish samples contained coliforms and faecal coliforms. No isolations of Staphylococcus aureus, Vibrio cholerae and Salmonella spp made from fish.
