Study Notes
Post-Mortem Inspection Principles
- 5 principles of post-mortem disposition.
- Applied to common diseases at Federally regulated slaughter facilities.
- Combines AM clinical signs & PM pathological findings to determine final disposition.
- Performed after ante-mortem inspection and slaughter.
- "post-mortem" meaning ‘after death’.
- Inspection site procedures vary based on: anatomical differences, diseases, and dressing procedures.
- Carcass identification is crucial
- Visual Inspection: obvious lesions or discoloration are noted.
- Olfaction: detect acetone, uraemia.
- Palpation: abscesses, neoplasms
- Enlarged lymph nodes are incised to detect tissue pathology.
Head Inspection
- Outer surface: Contamination, epithelioma, actinomycosis, and abscesses.
- Parotid, mandibular, and retropharyngeal lymph nodes are incised for TB lesions, actinomycosis, actinobacillosis, epithelioma, and abscesses.
- Masseter muscles are inspected for cysticercosis (Taenia saginata) and eosinophilic myositis.
- Tongue – Actinobacillosis
Visceral Inspection
- Esophagus: Cysticercosis (T. saginata)
- Tracheobronchial & mediastinal lymph nodes are inspected.
- Pluck (lungs, liver, heart): Tumors, pericarditis, pleuritis, pneumonia; TB lesions
- Abdominal viscera: Liver (flukes, abscesses) & bile ducts, spleen, mesenteric lymph nodes.
Carcass Condemnations
- Reasons for whole carcass condemnations in cattle:
- AM: Dead on arrival, downer, depressed, epithelioma, pyrexia, sometimes emaciated
- PM: Malignant lymphoma [BLV], pneumonia, epithelioma, peritonitis, septicaemia (beef cows)
Carcass Disposition & Condemnation
- Excision of localized lesions (eg. abscess from ham or bruised chicken limb) allows remaining tissue to pass.
- Heads with actinomycosis or actinobacillosis are condemned, except when disease is slight, localized, and without lymph node involvement.
Localized vs. Generalized Disease
- Localized process is characterized by the immune system containing pathological changes without systemic involvement.
- Generalization (systemic involvement) occurs when the Lymphatic or Circulatory system is involved.
- Acute vs chronic disease: acute is more significant than chronic.
Lymphatic & Circulatory System Examination
- The lymphatic system is key in determining localization vs. generalization.
- Circulatory system is essential in evaluating generalization.
- Haematogenous spread leading to abscessation in the: viscera, bone, and muscle, is indicative of generalization.
Septicemia & Systemic Disease
- Localized bacterial infections are trimmed away.
- Multiple lesions in multiple organs result in condemnation.
- Acute infections, especially those causing septicemias: anthrax, pyemias, toxemias and viremias, are more likely to be generalized.
- Advanced generalized [systemic] disease process often results from septicemic lesions.
- Septicemia is characterized by multiple foci of suppuration or abscessation.
