Questions and Answers

What are the primary objectives of antemortem inspection in animals destined for slaughter?

The primary objectives include screening animals, ensuring humane treatment, reducing contamination, and identifying diseases.

Why is it important to conduct antemortem inspections in proper lighting?

Proper lighting is essential for accurately observing animals' behavior, health status, and any abnormalities.

What types of abnormalities should inspectors look for during antemortem inspections?

Inspectors should look for abnormalities in respiration, behavior, gait, posture, structure, color, odor, and any abnormal discharges.

Antemortem Inspection

A process to screen animals for slaughter, ensuring proper rest, clinical information, and humane treatment.

Objectives of Antemortem Inspection

To screen animals, ensure proper rest and clinical data, reduce contamination, identify reportable diseases, and identify sick or treated animals.

Animal Abnormalities

Unusual signs in respiration, behavior, gait, posture, structure, discharges/protrusions, color, and odor, which indicate potential illness or injury.

Respiratory Abnormalities

Variations in breathing patterns, possibly indicating illness. Suspect animals with abnormal breaths.

Abnormal Animal Behavior Signs

Animals exhibiting abnormal behavior may display circular walking, unusual posture, head-butting, aggressive charging, or a dull, anxious expression.

Abnormal Gait Causes

An abnormal gait in animals often indicates pain in the legs, chest, or abdomen, or a nervous system disorder.

Structural Abnormalities

Structural abnormalities in animals can include swellings (like abscesses), enlarged joints, umbilical swelling (hernia), enlarged udder (mastitis), enlarged jaw (lumpy jaw), or a bloated abdomen.

Abnormal Body Discharges/Protrusions

Abnormal discharges or protrusions include nasal discharges, excessive saliva, afterbirth, vulva/intestinal/rectal/uterine protrusions, eye growths, and bloody diarrhea.

Postmortem Inspection Purpose

Postmortem inspection examines carcasses for abnormalities to ensure only fit products are consumed. It involves evaluating organs and carcasses for pathological lesions, determining if conditions are acute or chronic, and assessing systemic changes in organs. This process helps determine the significance of lesions and their impact on major organ systems.

Carcass Condemnation Criteria

Carcass condemnation applies to any abnormal or diseased portion, or any portion of a carcass that poses a health hazard or is repulsive to consumers.

Postmortem Inspection Techniques

Postmortem inspection uses visual examination, incisions, palpation, and smell to evaluate carcasses. It classifies lesions as acute or chronic, evaluates localization and systemic impacts, and considers primary and systemic lesion implications for major organs.

Carcass Trimming/Condemnation

Trimming or condemning a carcass involves removing parts with abnormalities or diseases, or parts potentially hazardous to or undesirable for human consumption.

Study Notes

Antemortem Inspection

  • Aims to screen all animals destined for slaughter
  • Ensures animals are properly rested and allows for clinical information gathering for disease diagnosis
  • Reduces contamination on the killing floor by separating dirty and diseased animals
  • Ensures injured animals receive emergency slaughter and humane treatment
  • Identifies reportable animal diseases to prevent contamination
  • Identifies animals treated with antibiotics, chemotherapeutics, insecticides, and pesticides
  • Requires proper cleaning and disinfection of livestock transport trucks
  • Inspections should be performed with proper lighting to observe animal behavior, nutritional status, cleanliness, and signs of disease/abnormalities
  • Abnormalities in respiration - different breathing patterns
  • Abnormalities in behavior - includes walking in circles, abnormal gait/posture, head-butting, charging at objects, aggressiveness, dullness/anxiety in eyes
  • Abnormal gait – associated with pain in legs, chest, or abdomen, or nervous disease
  • Abnormalities in structure/conformation - includes swellings (abscesses), enlarged joints, umbilical swelling, enlarged jaw ("lumpy jaw"), bloated abdomen, abnormal discharges/protrusions (nose, mouth, vulva, rectum/uterus, vagina, growths on eyes, bloody diarrhoea)

Postmortem Inspection

  • Crucial for detecting carcass abnormalities and ensuring only fit products are passed as food
  • Keeps organs and carcass portions together
  • Utilizes professional/technical knowledge to evaluate pathological lesions
  • Viewing, incision, palpation, and olfaction techniques are employed
  • Classifies lesions as acute or chronic
  • Establishes condition localization/generalization and extent of systemic changes in other organs/tissues
  • Determines significance of primary/systemic lesions and their relevance to major organs (liver, kidneys, heart, spleen, lymph system)
  • Coordinates antemortem and postmortem findings to make a final diagnosis
  • Submits samples to a lab for diagnostic support if applicable

Carcass Judgement/Trimming/Condemnation

  • Involves removing any portion of a carcass that is abnormal or diseased
  • Removes any carcass part that may pose a hazard to human health
  • Removes any part of the carcass that is repulsive to the consumer

Specific Inspection (Cysticercus Bovis)

  • Part of inspection for cattle/calves over 6 weeks
  • The muscles of mastication should be viewed and incised.
  • Linear incisions are aligned parallel to the lower jaw, reaching the internal and external muscles of mastication.
