Abstract

This study identified microbial risk factors in agricultural products processing center (APC) through the microbialhazard analysis to introduce good agricultural practices (GAP) system in APCs. Samples were collected from surroundings(basket, tray loader, weighing cup, collector, box) and workers by swabbing (glove and cloth) and glove juice method (hand)to enumerate total bacteria, coliform, Staphylococcus aureus, Escherichia coli, Escherichia coli O157:H7 and Salmonella. Thelevels of total bacterial and coliform populations recovered from surroundings were 2.4-5.7log CFU/100cm2 and 2.3-5.7logCFU/100cm2 or hand for surroundings, and workers, respectively samples were 2.3-5.7log CFU/100cm2 or hand. Escherichiacoli populations were determined to be below detection limit. S. aureus and Salmonella populations recovered fromsurroundings were 3.0-4.4log CFU/100cm2 and close to detection limit, respectively. Corresponding bacterial populations toworker’s samples were 2.8-5.2log CFU/100cm2 or hand (S. aureus) and below detection limit (Salmonella). Bacterialpopulations of APC certified facilities were similar (p≥0.05) with those of uncertified facilities. These results showed thatthis study should be useful in development of GAP models to improve microbial safety in APCs.
