Effect of Food Sanitation Knowledge and Behavior Program on Against E-coli Bacterial Presence in Eatery and Food Stands in Phakdeechumphol District, Chaiyaphum Province.

Abstract

      This action research aimed to develop and evaluate a food sanitation knowledge and behavior enhancement program among restaurant and street food vendors in Phakdi Chumphon District, Chaiyaphum Province, Thailand. Seventy participants were purposively selected, including 35 members of the District Quality of Life Development Committee and Food Safety Committee and 35 food vendors. Data were collected using questionnaires, knowledge tests, behavioral assessments, food sanitation inspections, and focus group discussions. Quantitative data were analyzed using descriptive statistics and paired t-tests, while qualitative data were analyzed through content analysis.

      The program comprised situation analysis, participatory planning, training, monitoring and evaluation, and reflection. Following implementation, committee members demonstrated significantly improved knowledge and participation, while food vendors showed significant improvements in food sanitation knowledge and practices (p < 0.001). The number of establishments meeting food sanitation standards increased, and coliform contamination in food, food handlers’ hands, and utensils decreased.
