Nearly half (50.6%) and 50.9% of study subjects were poor in food hygiene knowledge and practice respectively. Significant relationships were found between knowledge and practice (β1 = 0.46, p < 0.001), and also knowledge and attitude ((β1 = -0.38, p < 0.001). Male food vendors (AOR: 2.05, 95% CI (1.25, 3.10)), food vendors with poor food hygiene attitude (AOR: 2.54, 95% CI (1.65, 3.90)), and those not receive feedback from the customers on food hygiene (AOR: 2.14, 95% CI (1.40, 3.27)) were poor in food hygiene knowledge.
