Meat Inspection II Flashcards
What methods are used to detect diseases, abnormalities, and contamination of meat?
sight, feel, smell, hearing.
Why is it important to look at the lymph nodes when assessing the health of an animal?
Because they are the first tissues to become affected when toxins or organisms spread around the body.
What steps are involved in the postmortem inspection process for livestock?
head inspection, viscera inspection, and carcass inspection.
What should you do if abnormalities are noted during the inspection?
if the condition/disease is localized, trim the affected tissue and pass (+/- restrictions). If the disease is generalized, retain it for vet disposition.
Why do you slice the masseter muscle?
To look for cysticercosis or eosinophilic myositis.
When inspecting the head, the tongue is palpated to ID what?
wooden tongue or eosinophilic myositis.
Cutting into the left ventricle of the heart while inspecting the viscera rules out what?
pericarditis, cysticercosis, or endocarditis.
Lungs are palpated and the mediastinal and tracheobronchial nodes are incised to rule out what?
pleuritis, pneumonia, and TB in lymph nodes.
The hepatic nodes are incised, bile ducts opened and all surfaces are palpated to rule out what?
ascarids, liver flukes, abscesses, cirrhosis, hydatid cysts, and fatty liver.
Should the digestive tract be opened?
No.
The rumino-reticular junction is palpated for what?
hardware disease
What does adulterated mean?
including an added, foreign, or interior substance, that cannot be removed by trimming.
What are some specified risk materials?
tonsils and the distal ileum in all ages of animals. If over 30 months, brain, skull, eyes, trigeminal ganglia, spinal cord, vertebral column, and dorsal root ganglia are also SRMs.
Under what circumstances is trimming permitted?
when there is local involvement with diseases not transmissible to humans.
When is meat passed with restrictions?
When the risk is minor and can be mitigated by cooking, freezing, etc.
