Abstract
This study identified microbial risk factors in agricultural products processing center (APC) through the microbial hazard 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. The levels of total bacterial and coliform populations recovered from surroundings were 2.4-5.7 log CFU/100 $cm^2$ and 2.3-5.7 log CFU/100 $cm^2$ or hand for surroundings, and workers, respectively samples were 2.3-5.7 log CFU/100 $cm^2$ or hand. Escherichia coli populations were determined to be below detection limit. S. aureus and Salmonella populations recovered from surroundings were 3.0-4.4 log CFU/100 $cm^2$ and close to detection limit, respectively. Corresponding bacterial populations to worker's samples were 2.8-5.2 log CFU/100 $cm^2$ or hand (S. aureus) and below detection limit (Salmonella). Bacterial populations of APC certified facilities were similar (p${\geq}$0.05) with those of uncertified facilities. These results showed that this study should be useful in development of GAP models to improve microbial safety in APCs.
