This study surveyed the prevalence of traumatic reticular diseases (TRD) of slaughter cattle in Korea, the typology of the causative foreign bodies and the effects on beef quality and carcass weight. The overall prevalence of TRD in 3,121 slaughter cattle was 5.5%. However, the prevalence was significantly higher in Korea indigenous cattle Hanwoo (5.8%, p<0.05) and female cattle (20.75%, p<0.001). The prevalence significantly increased in aged cattle (p<0.001). Major lesions related to foreign bodies were reticulitis (96%) and peritonitis (86%). Most causative foreign bodies were made of iron including nails, wires, steel rods, screw nails, and syringe needles. Cattle affected with TRD produced significantly lower grade quality of beef compared to normal cattle (p<0.0001), but TRD did not affect carcass weight. The data will be useful in the management of TRD, with the aim of increasing beef productivity in Korea.
