Abstract

Despite the recent increase in the consumption level of the processed meat-byproducts, the health and safety issue has consistently been raised in the processes of production, distribution and consumption. The purpose of this study is to analyze and evaluate the microbiological hazard elements in the Korean sausage, "Sundae," to present not only the safety standard of meat by-product vendors based on HACCP (Hazard Analysis Critical Control Point), but also the quality control criteria and sanitary arrangements of small manufacturers. For the study, the microbiological hazards in 24 raw materials, 7 manufacturing processes, 40 facilities and tools, 17 workplace environment, and 12 workers were analyzed. The analysis revealed the hazardous elements in the initial stages with 6.28 and 4.07 log CFU/g of total aerobic count and coliforms, respectively, detected from the porcine blood and 3.23 log CFU/g of coliforms from the porcine small intestines. The result also showed that the total aerobic counts and coliforms in the process of mixing and filling process exceeds the standards in the hygiene guidelines by Natick with the total aerobic counts of 5.23, 5.45 log CFU/g, and the coliforms of 3.25, and 3.31 log CFU/g, respectively. Although the detected total aerobic count and the coliforms in the filling and washing rooms exceeded the standards, it was found that the total aerobic count was significantly reduced by 98% after cleaning and disinfecting and no coliforms was detected in any process thereafter. In order to achieve high level of safety in the manufacturing processes of Sundae, the separation of washing and disinfection room from the other sections and the sanitation control of the workers must be preceded, along with strict monitoring in the storage and distribution processes. The study raises necessity for additional studies for the safety evaluation of the processed meat-byproducts and further researches on the validity of the critical limits.

최근 식육부산물 가공식품의 소비량 증가에도 불구하고 식육부산물의 생산, 유통 그리고 소비과정에서 위생안전문제가 지속적으로 제기되고 있다. 본 연구에서는 순대의 위해요소를 분석, 평가하여 Hazard Analysis Critical Control Point에 근거한 식육부산물 생산업체의 미생물학적 안전성 확보와 소규모 제조업체의 품질관리 기준 설정 및 위생관리체계를 확립하고자 하였다. 이를 위해 순대 생산에 적용되는 원료(24건), 제조공정(7단계), 제조설비 및 도구(40건), 작업장 환경(17구역), 작업자(12명)에 대한 미생물학적 위해요소를 분석하였다. 원·부재료 돈혈의 일반세균과 대장균군 각각 6.28±0.48, 4.07±0.42 log CFU/g 검출되었고, 돈소창의 대장균군 3.23±0.16 log CFU/g 검출되어 초기단계의 위해요소가 지적되었다. 혼합과 충진공정에서의 일반세균은 각각 5.23±0.17, 5.45±0.37 log CFU/g, 대장균군은 각각 3.25±0.23, 3.31±0.24 log CFU/g로 높게 나타나 미국 육군 Natick의 위생가이드라인에서 제시한 기준을 초과하여 검출되었다. 작업장 충진실과 돈소창 세척실의 일반세균과 대장균군은 기준치를 초과하였으나 세척·소독 후 일반세균은 약 98% 미생물 오염도가 급격히 감소하였고, 대장균군은 모든 구역에서 불검출 되었다. 순대 제조공정의 안전성 확보를 위해서는 세척·소독 및 구역별 분리와 작업자의 위생관리가 선행되어야 하며, 제품의 보관 및 유통단계의 철저한 관리가 필요할 것을 제안한다. 향후 식육부산물의 활용한 가공식품의 안전성평가를 위한 추가적인 연구와 한계기준 유효성평가를 위한 연구가 지속되어야 할 것으로 사료된다.
