GAP 인증∙미인증 상추 및 오이 농가의 미생물학적 오염도 평가

Abstract

The aims of this study were to investigate microbial contamination levels and to survey sanitation management between Good Agricultural Practices(GAP) and non-GAP farms of lettuce and cucumber. The samples(lettuce, cucumber, soil, agricultural water, gloves, and packing plastic bag) were tested to analyze sanitary indicator bacteria(total aerobic bacteria, coliforms and Escherichia coli) and major pathogenic bacteria(Staphylococcus aureus, Bacillus cereus). In the lettuce farms, the contamination levels of total aerobic bacteria and coliforms in GAP farms were little lower than non-GAP farms or similar. Staphylococcus aureus and Bacillus cereus in soil and agricultural water of GAP farms were detected at higher levels than non-GAP farms in soil and agricultural water. In the case of cucumber farms, levels of total bacteria and Bacillus cereus in soil and total bacteria and coliform in gloves of GAP farms were higher than those of non-GAP farms, and other bacteria contamination levels in collected samples were similar. These results indicate that agricultural products produced from GAP farm still exhibited potential microbial risks. According to the field survey, a sanitation management in GAP farms was insufficient. These results could be useful as basic data to suggestion of plan for preventing microbial contamination and to improvement of GAP certification.
