Ovine PM Inspection Flashcards
- What must the Food Business Operator firstly do in terms of SRM?
- How is this regulated?
- Establish a system which identifies animals that are either >1yr old, or have 1 or more permanent incisor/s erupted, to allow SRM to be removed from the carcase.
Should be part of the FBO’s HACCP based procedure. - FSA staff will check 5% of ovine / caprine presented as ‘young’ to ensure FBO’s systems are functioning correctly.
Head inspection.
Routine inspection:
- <1yr old:
– visual inspection of head, incl. throat, mouth, tongue, and retropharyngeal and parotid LNs.
–> Not necessary if competent authorities able to guarantee head (incl. tongue and brain) will be excluded from human consumption.
- >1yr old:
– visual inspection of head, incl. throat, mouth, tongue and parotid LNs, and palpation of retropharyngeal LNs.
–> Not necessary if competent authorities can guarantee that head (incl. tongue and brain) will be excluded from human consumption.
Inspection in case of suspicion.
- <1yr old:
– palpation of throat, mouth, tongue, and parotid LNs.
–> unless animal-health rules provide otherwise, these examinations are not necessary if competent authorities able to guarantee head (incl. tongue and brain) will be excluded from human consumption.
- >1yr old:
– palpation of throat, mouth, tongue and parotid LNs.
–> unless animal-health rules provide otherwise, examinations not necessary if competent authorities able to guarantee head (incl. tongue and brain) will be excluded from human consumption.
HEADS GOING FOR MEAT ARE ILLEGAL IF ANIMAL >1YR OLD.
Heart inspection.
Every sheep:
- visual inspection of pericardium and heart.
- ONLY INCISE HEART IF SUSPICION.
Lung inspection.
Visual inspection of lungs, trachea and oesophagus and the bronchial and mediastinal LNs.
- incision and palpation if necessary due to suspicion.
Kidney inspection.
Visual inspection of the kidneys.
- Incision if suspicion.
What does the ‘pluck’ consist of?
Heart, lungs, liver.
- What are you looking for when inspecting the heart?
- What are you looking for when inspecting the lungs?
- Liver?
- Cysts of cysticercus bovis.
- Lungworm.
- Fluke (fascioliasis).
Inspection of green offal.
Visual inspection of GIT, mesentery, gastric and mesenteric LNs (all sheep).
No incisions.
- Category rejection if liver fluke found?
- Category rejection if cysticercus tenuicollis migratory scarring found?
- what if cysts present?
- Reject liver only under category 3 animal by-product for aesthetics.
- Reject liver only under category 3 animal by-product for aesthetics.
- rejection under category 2 animal by-product as pathogenic to dogs (taenia hydatigena).
- What is hydatidosis caused by?
- rejection category if found? - What rejection category if neoplasia found in liver?
- Echinococcus granulosus (canine tapeworm).
- rejection of affected part under category 2 animal by-product as pathogenic to animals. - Rejection of affected part only, unless multiple organs or malignant, under category 2 animal by-product tradition, as no one wants to eat cancer and no one wants cancer in pet foods.
- Enzootic pneumonia rejection category.
- Fibrinous pneumonia rejection category?
- (Affects cardiac lobes).
Reject affected part only under category 2 animal by-product as pathogenic to animals as possibly mycoplasma ovipneumoniae. - Reject affected part only under category 2 animal by-product pathogenic to animals as possibly Mannheimia haemolytica.
- Secondary fibrinous pneumonia rejection category?
- What is the only thing that causes pneumonia at the bottom of the sheep lung?
- rejection category?
- Reject affected part only under category 2 animal by-product as pathogenic to animals.
- Dictyocaulus filaria.
- category 3 rejection for aesthetics as not pathogenic.
- Cysticercus ovis in the heart rejection category?
- Vegetative/valvular endocarditis rejection category?
- Category 2 rejection of affected part only unless generalised throughout the carcass, then total rejection, as pathogenic to animals.
- Reject affected part, or total rejection if infarction in kidneys, under category 2 animal by-product as pathogenic to humans or animals.
- Rejection category for renal abscesses?
- Rejection category for infarcts in the kidney?
- Reject affected part under category 2 and check carcass for signs of systemic dz and reject whole carcass if found, as pathogenic to humans or animals.
- Category 2 rejection of affected kidney as pathogenic to animals or humans and check whole carcass for signs of systemic dz and reject if found. (e.g. open heart to look for valvular/vegetative endocarditis).
- Lymphosarcoma of the kidney rejection category.
- Rejection category where enlarged spleen is found?
- Reject affected part under category 2 unless other organs affected or malignant, then reject whole carcass. Rejection is under category 2, not due to pathogenicity but due to tradition because it is cancer.
- Reject affected part and check carcass for signs of systemic infection (can be sign of septicaemia). Rejection is under category 2 as pathogenic to humans or animals.
- Rejection category for splenic neoplasia?
- Rejection category for caseous lymphadenitis?
- Reject affected part only, unless multiple organs affected or malignant, then reject whole carcass. Rejection under category 2, not because of pathogenicity, but due to tradition as is cancer.
- Reject affected part, check carcass for systemic infection. Reject under category 2 as pathogenic to humans or animals.
- zoonotic – Corynebacterium pseudotuberculosis.
- Mesenteric LN tuberculosis rejection category.
- Cysticercus tenuicollis rejection category?
- Reject affected part, check carcass for signs of systemic infection, if present in lungs or other system, total rejection.
Reject under category 2 as pathogenic to humans or animals. - Reject affected part only under category 2 as pathogenic to humans or animals.
- Enteritis rejection category?
- Moniezia expansa (tapeworm) rejection category?
- (offal purple-red).
Reject affected part, check carcass for signs of systemic spread or evidence of emaciation. Rejection is under category 2 animal by-product as possibly pathogenic to humans or animals. - Will be extruded from intestines during any further processing with intestinal contents. Reject under category 3 animal by-product as non-pathogenic to humans or animals
- Oedema rejection category?
- Reject affected part, check carcass for signs of systemic infection or evidence of emaciation.
Reject under category 2 animal by-product as pathogenic to humans or animals.
Carcass inspection.
<1yr old:
- Visual inspection of diaphragm, pleura, peritoneum, umbilical region and joints.
- if suspicion, palpate umbilical region and joints, incise these and examine synovial fluid.
>1yr old:
- Visual inspection of diaphragm, pleura, peritoneum, genital organs (except penis if already discarded), udder and LNs.
Check for contamination in pelvic channel.
Check LNs for signs of infection,
Palpate for signs of C. ovis, peritonitis.
Check for signs of pleuritis and contamination.
Inspect kidneys.
- Arthritis rejection category?
- Cysticercus ovis rejection category?
- Reject affected part only under category 2 as pathogenic to humans or animals. Consider if transportation was an issue.
If septic, check carcass for sign of systemic spread. - Reject affected part and check carcass for signs of generalised infection.
Rejection under category 2 animal by-product pathogenic to humans or animals - taenia ovis = canine tapeworm cyst.
- Generalised lymphadenitis rejection category?
- Emaciation rejection category?
- Pleuritis rejection category?
- Total rejection of the whole carcass as generalised infection demonstrated. Reject under category 2 as pathogenic to humans or animals.
- Total rejection of the whole carcass as generalised infection demonstrated. Reject under category 2 as pathogenic to humans or animals.
- Affected part rejected, check carcass for signs of generalised infection. Rejection under category 2 as pathogenic to humans or animals.
Wool pull rejection category?
Capillary tearing - does not change colour so time frame cannot be established. Reject affected part only under category 3 animal by-product due to aesthetics.
