축산물이력제를 활용한 수도권에서 유통 중인 한우고기 유통환경조사

Abstract

The objective of this study was to investigate the distribution conditions for Hanwoo in capital area. Hanwoo beef samples(n=206) were collected in Seoul from June 2022 to April 2023. The individual information, distribution time, distributionchannel, and distribution location for the samples were collected with the animal products traceability system. In addition, the exposure temperature of Hanwoo beef from retail stores to the final consumption place was collectedfrom the regional temperature observation data from the Korea Meteorological Administration for the dates the samplecollected. It was found that the proportion of Hanwoo beef distributed in Seoul was the highest in 30–39-month-oldand steers. Regarding the location of each distribution channel, slaughterhouses and meat packaging companies hadthe highest share in Gyeonggi-do. Transport times were 4.3–249.5 min from the slaughterhouse to the meat packagingbusiness, 64.1–141.0 min from the slaughterhouse to the meat sales business, and from 19.4–344.0 min from the meatpackaging business to the meat sales business. Finally, it took 22.0 to 88.0 min from the meat sales business toconsumers. The atmosphere temperature ranges to which Hanwoo beef is exposed from the meat sales business tothe consumer were –2.1℃–28.8℃ in spring and fall, 18.1℃–33.4℃ in summer, and –9.6℃–14.3℃ in winter. Thus, consumersshould not expose Hanwoo beef to a temperature suitable for the microbial growth for a long time during the transportto the final consumption place. This result might be useful in distribution simulation for the microbial fates withthe predictive models and in the microbial risk assessment.
