Isolation and identification of selected bacterial pathogens from various markets in Windhoek

Abstract

This study assessed the microbiological quality of fresh fish, specifically focusing on bacterial contamination. Fish samples, including Merluccius species (hake) and Trachurus species (horse mackerel), were collected from wholesalers and retailers in Windhoek, Namibia. The key bacterial pathogens such as Salmonella species, Shigella sonnei, Staphylococcus aureus and Escherichia coli, were isolated and identified through standard microbiological methods. The presence of these pathogens indicates potential health risks, such as foodborne illnesses and underscores the need for stringent quality control in fish handling, processing, and storage. The findings highlight the importance of public health interventions and quality assurance measures to ensure consumer safety and maintain industry reputation.
