Arthritis in slaughter pigs.
Joints obtained from 192 pig carcases were examined by means of standard microbiological and macro- and histopathological procedures. Approximately 32% of the joints were considered normal; 35.5% showed lesions consistent with osteochondrosis and a non-specific synovitis was present in 24.4%. Only 6.1% of joints were arthritic and yielded either Staphylococcus aureus or Streptococcus spp. The remainder (2.3%) had periarticular lesions such as abscesses. The study emphasises that an accurate diagnosis and correct evaluation of pig carcases showing joint lesions, is absolutely essential if a high standard of meat inspection is to be obtained and unnecessary economic losses are to be avoided.
