1reasons for carcass rejection
pathogenic to huamsn
aesthetic
legal requirement-
2what in 627 says when animal cant enter food chain
no ante mortem inspection
dereives from animals whose offal has no inder gone post mortme insepction
diseased
breaks food safety
parasite infection
chemical residues
contaminants
illegal substances
radiation exposed
FB
pathological or organileptic changes
emaciated animal
SRM
soiling/ faecal contam
3what must be done for different species at insepction
all: visual cavity and organ
sheep <12 months= visual, >12 months= visual and incision/ palpation
cattle <8months= some palpations >8months= palpate lungs, gastic and mesenteric LNs. incise masseater, heart, and other LNs
4what to do if not sure after palpating
can detain and come back to it at the end to look into greater detail
5what to look for on the head
• Malignant catarrhal fever
• Infectious keratoconjunctivitis (related to welfare of transport)
• Sarcocysts
• Stomatitis
• Melanosis
• Actinomycosis, Actinobacillosis- lumpy jaw and wooden tongue
• Xanthosis
• Foot and mouth
• Abcesses
• Cysticercus bovis
• Tuberculosis- shouldnt have been sent
@ Tumours- rare.
• Oesteohaematochromatosis,
• Ringworm
6what disease does APHA like to hear about
tumours
7what to look for in liver
bovine fascioliasis- reject for humans, pet food okay
8things to look for in heart
endocarditis, myocarditis and septicaemia signs- destroy
9what to look for on lungs
consolidation abscesseda and lungworm
call APHA if find TB- condem
10what to do with kidneys
urolithiasis or nephritis- just bin the kidneys
peterchaition- condem whole body
11what to do with offal
green offal- inspect
compare LNs to rest of body
washed and look for parasites
12what does being inspected mean after
cleared of patohlogy, contamination and SRM
healh marked= fit for human consumption and magggically sterile.
microbiologically tested- just a pre requisite. not a CCP. chilled whil waiting, for chicken sold of and recalled if bad.
13what is the purpose of marking meat
tracebility, given a number
abbatoir approval number, couttry code
EC in the EU
14challenges of PMI
fastm oving
notifiables can be missed
cold and loud
15parasites in cows
cystecicus bovis- taenia saginata, small and hard
cystercisuc teniicollis- water bladder
echinococcus granulosus
dictyocaulus- shot gun pattern
16parasites eith human definitie hosts
taenia solium- pig intermediate
taenia saginata- cattle intermediate
17parasites with dogs/ foxes as definitive hosts
taenia hydatigena- sheep intermediate- human rare
taenia ovis- sheep IH, human rare
taenia multiceps- sheep IM, humans rare
echinococcus granulosus- sheep IM, humans can get
echinococcus multiocularis- rodents IH
18what does taenia solium pose as arisk to humans
if we eat the eggs and it cysts in us can form neurocyticercosis
life long epilepsy form
19CCP in an abbatoir
dehiding
evisceratiion
/ZFT in USA
chilling
20important points in abbatoir
ante mortem inspection
primary meat insepction
remove SC
treatment or disposal if needed a secondary inspection
21what is liveweight
animal before slaughtered
22what is hot carcase weight
the unchilled weight of the slaughtered animal’s body
after being skinned, bled and eviscerated, and after
removal of the external genitalia, the limbs, the head,
the tail, the kidneys and kidney fats, and the udder
23what is cold weight
The chilled weight of the carcass described above,
widely adopted as 2% lower than the hot weight. Used
to calculate the payment rate to the supplier.
24Killing out percentage
The carcass weight expressed as a percentage of
liveweight
25meat yield
total percentage of saleable meat from a carcass
26what is the specification of meat acronym
SEUROP= pigs and sheep
EUROP= cattle
super= double meat animals
27how is fat graded
1- leanest
5- fatest
+ and - sub levels
