Study Notes
Septicemia and Toxaemia
- Septicemia can only be diagnosed by isolation of the causative organism from the blood stream.
- Evidence of septicemia is determined by ante-mortem and post-mortem findings.
- Toxaemia is a medical condition characterized by the presence of bacterial toxins in the blood stream.
- Clinical signs and post-mortem findings of toxaemia are similar to those of septicemia.
Antemortem and Postmortem Inspection
- Antemortem inspection is used to screen all animals destined for slaughter, ensure proper rest, and obtain clinical information for disease diagnosis and judgement.
- Postmortem inspection is carried out to detect any abnormalities in the carcass and to provide necessary information for the scientific evaluation of pathological lesions.
Carcass Judgement
- Trimming or condemnation may involve any portion of a carcass or a carcass that is abnormal or diseased, or affected with a condition that may present a hazard to human health or be repulsive to the consumer.
- Coordinating antemortem and postmortem findings is necessary to make a final diagnosis.
Edema
- Antemortem findings of edema include depression, drowsiness, swelling of various body parts, and edematous tissue that is cool to the touch and has a firm, doughy consistency.
- Postmortem findings of edema include wet, sloppy musculature that pits on pressure, and accumulation of clear or faint yellow fluid in the thorax, abdomen, and subcutaneous tissue.
- Animals affected with generalized edema may be condemned on antemortem inspection, while less severe non-generalized cases are treated as "suspects".
- The carcass may be totally or partially condemned depending on the extent and cause of the condition.
