Abstract

Red pepper is widely used as a spicy flavor ingredient in the food industry and many households. The objective of this study was to assess the total aerobic bacteria count, coliforms count and incidence of Escherichiacoli, Salmonella spp., Escherichiacoli O157:H7, Listeria monocytogenes, and Bacillus cereus in red pepper and red pepper cultivated soil. The total aerobic bacteria number in red pepper and soil were in the range of 2.97 to 8.13 and 5.91 to 7.65 log CFU/g, respectively. The coliforms in red pepper and soil were in the range of 1.87 to 6.71 and 0.67 to 6.16 log CFU/g, respectively. E. coli was detected in 3 of 54 soil samples. In 3 out 63 red pepper and 53 of 54 soil samples, B. cereus was detected, while Salmonella spp., E.coli O157:H7, and L.monocytogenes were not detected. The results from this study provide an important basic information associated with the microbiological safety of fresh vegetables. Continuous caution is needed to prevent the contamination of pathogenic microorganisms during its farming.

고추는 한국의 식생활에서 필수적인 향신료로서 대부분이 건조 보관되면서 소비되고 있으며 식품 제조용 및 조미료로써 광범위하게 활용되고 있다. 고추와 고추 재배 토양에서 미생물 오염도를 확인하고자 본 연구에서는 고추 재배 농가(I, II, III, IV, V)에서 시료를 채취하여 일반세균수, 대장균군, 대장균은 정량적 분석을 수행하였고, Salmonella spp., E. coli O157:H7, L. monocytogenes, B. cereus는 정성적 분석을 수행하였다. 고추 63점과 재배 토양 54점의 일반세균수는 각각 2.97~8.13 log CFU/g, 5.91~7.65 log CFU/g이었고 재배 토양이 고추보다 좀 더 높은 미생물 분포를 보였다. 대장균군은 고추에서, 그 범위가 1.87~6.71 log CFU/g 수준으로 나타났고 재배 토양에서, 그 범위는 0.67~6.16 log CFU/g 수준으로 나타났다. 대장균은 고추에서는 전혀 검출되지 않았고 토양 시료 54점 중3점(6%)에서 0.83~4.36 log CFU/g 수준으로 검출되었다. 5개 농가의 고추, 재배 토양 시료에서 Salmonella spp., E. coli O157:H7, L. monocytogenes등은 검출되지 않았고, B. cereus는 고추 63점 중 3점(5%)에서 검출되었고 재배 토양 54점 중 53점(98%)에서 검출되었다. 농산물에서의 미생물 오염은 생산, 가공, 유통의 전 과정에서 일어날 수 있으므로 각 단계에서의 철저한 위생관리가 요구된다.
