This has the potential to cause outbreak of diseases. This study therefore sought to assess the microbiological safety and hygienic practices of food vendors and handlers in Nalerigu and Gambaga, Ghana. A cross sectional study was conducted, using fifty rice and tuo zaafi (local food) food vendors, purposively selected from the communities within the study area. Structured questionnaires, observations, and hand swab test were performed following standard procedures. The results indicated that 20 (40%) of the food vendors have medical certificate to sell. In total, 25 (50%) prepared their food under poor sanitary conditions, 15 (30%) under average sanitary conditions, and 10 (20%) under strict sanitary conditions. Results from the hand swabbed test indicated a microbial load of 6.74 ×102 cfu/ml at Nalerigu Station and loads of 7.55×102 cfu/ml, 6.78×102 cfu/ml and 1.05×102 cfu/ml at selling area two, selling area Three and selling area four respectively, for Staphylococcus aureus count. For Salmonella spp., loads of 7.40 × 102 cfu/ml, 6.15 × 102 cfu/ml, 6.33 ×102 cfu/ml and 11.37 ×10 2 cfu/ml were recorded at Nalerigu Station, Nalerigu Market, Gambaga Station and Gambaga market respectively. Escherichia coli load ranged from 9.4 × 101 MPN/100ml at Gambaga Market to 1.16 × 102 MPN/100ml at Nalerigu Station. These findings lead to the conclusion that rice and tuo zaafi food vendors in Nalerigu and Gambaga communities generally do not adhere to food hygiene practices and microbiological safety measures. The training of rice and tuo zaafi food vendors on food hygiene has not yielded significant results as most food vendors are mostly illiterate or semi-literate and regulatory bodies inadequately resourced. The study proposes development of training programmes for food vendors as well as capacity building of the stakeholders to protect public health.
