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 study employed a quasi-experimental research design with a one-group pretest–posttest approach. The objective was to examine the effects of a program for developing knowledge and behaviors related to food sanitation among food establishment operators and food handlers in restaurants and street food stalls in Phakdi Chumphon District, Chaiyaphum Province. Data were collected using a knowledge test, a questionnaire, and standardized assessment forms for restaurant and street food stall sanitation. The data were analyzed using descriptive statistics, including frequency, percentage, mean, and standard deviation, as well as inferential statistics using the dependent t-test.

      The results revealed that after the implementation of the food sanitation knowledge and behavior development program, the mean scores of knowledge and food sanitation behaviors among restaurant and street food stall operators were significantly higher than those before the intervention at the 0.05 level. In addition, following the implementation of the program, the number of restaurants and street food stalls that met the standard food sanitation criteria increased. These findings indicate that the program was effective in improving food sanitation knowledge, promoting appropriate sanitation behaviors, and enhancing compliance with food sanitation standards among food establishments in the study area.
