Abstract

Soybean farms in Changnyeong were selected for hazard analysis to establish the Good Agricultural Practices (GAP) model of soybean, and physical, chemical(heavy metal) and biological(sanitary indications, foodborne pathogens) hazard analysis for cultivation environment (soil, water) was carried out. First, bow which is able to be mixed in soil and water was confirmed as physical hazard. Levels (Cd:0.01~0.103, Cu:0.001~6.036, As:0.006~3.045, Hg:ND~0.041, Pb:0.003~3.952, $Cr^{+6}$:0.007~0.496, Zn:0.001~66.500, Ni:0.003~18.010) of heavy metals in soil and water were appropriate for GAP criteria. In biological hazard, APC and coliform in soil were detected at the levels of $6.0{\pm}0.3$ and $3.6{\pm}1.6$ log CFU/g, and levels of water were $3.5{\pm}0.7$ and $1.9{\pm}0.7$ log CFU/mL, while E. coli wasn't detected in all sample. However, coliform in water wasn't appropriate for criteria, and E. coli O157 was detected about 22% in some farms, so it needs ways to prevent contamination by human and animals excrements. In conclusion, it needs proper management to prevent cross-contamination of hazards although physical and chemical hazard level were appropriate for GAP criteria while biological hazard wasn't.

콩 GAP 모델 확립을 위해 경남 창녕에 소재한 콩 재배농가 3 곳을 선정하여 각 재배환경에 대한 물리적, 화학적(중금속) 및 생물학적(위생지표세균, 병원성 미생물) 위해요소를 분석하였다. 재배환경에 대한 물리적 위해요소로는 토양과 농업용수에 혼입될 수 있는 이물 등으로 확인되었고, 화학적 위해요소 중 토양과 농업용수에서의 중금속 (Cd:0.01~0.103, Cu:0.001~6.036, As:0.006~3.045, Hg:ND~0.041, Pb:0.003~3.952, $Cr^{+6}$:0.007~0.496, Zn:0.001~66.500, Ni:0.003~18.010)이 모두 허용기준치 이하로 검출되었다. 생물학적 위해요소의 경우, 위생지표세균은 토양에서 일반세균과 대장균군이 $6.0{\pm}0.3$ 및 $3.6{\pm}1.6$ log CFU/g, 농업용수는 $3.5{\pm}0.7$ 및 $1.9{\pm}0.7$ log CFU/mL 수준으로 각각 검출되었고, E. coli는 모든 시료에서 불검출 되었다. 그러나 농업용수에서 대장균군이 허용기준치를 초과하였고, E. coli O157도 토양 중에서 약 22%가 검출됨에 따라 분변오염 방지를 위한 적절한 방안이 필요할 것으로 판단된다. 결론적으로 재배환경 중 물리적 및 화학적 위해요소 (중금속)의 오염수준은 허용기준에 적합했지만, 생물학적 위해요소의 경우 농업용수에서 대장균군이 기준치를 초과함에 따라 최종산물로의 교차오염을 방지하기 위한 체계적인 관리방안이 모색되어야 할 것으로 판단된다.
