The present invention relates to a processing method for livestock product distribution, by which livestock products including beef and pork warehoused after slaughtering are pre-processed before mincing for uniform meat quality maintenance, the meat quality maintenance can be further stabilized in the form of foreign matter removal, microbial growth prevention, and the like by the mincing process being subdivided and air wash, drying, cleaning, and gas injection processing processes and the like being specifically added between the mincing processes, and the meat quality preservation can be maximized through packaging and refrigeration processing before shipment. The processing method for livestock product distribution according to the present invention for achieving the purposes described above includes: a step (S10) of pre-processing the warehoused livestock product for livestock product distribution processing； a step (S20) of primarily mincing the pre-processed livestock product for halving to quartering； a step (S30) of secondarily mincing the livestock product processed through a predetermined process after the primary mincing； a step (S40) of tertiarily mincing the livestock product processed through a predetermined process after the secondary mincing； and a step (S60) of performing packaging (S50) and then refrigeration processing on the livestock product processed through a predetermined process after the tertiary mincing. Step S10 described above includes: a pre-processing packaging step (S11) for ripening using an air-permeable material； a primary refrigeration processing step (S12) for livestock product meat quality maintenance after the pre-processing packaging step and before the primary mincing； and a primary cleaning step (S13) for smooth mincing during the primary mincing.본 발명은 도축된 후 입고된 우육, 돈육을 포함한 축산물을 세절 전 전처리하여 육질이 골고루 유지될 수 있도록 하고, 세절 과정을 세분화함과 함께 각 세절과정 사이에 에어워시, 건조, 세척 및 가스분사처리 과정 등을 구체적으로 부가함으로써 이물질 제거와 함께 미생물 번식 방지 등 육질 유지가 더욱 안정되게 이루어지도록
