Q

stress associated with transport

A
Expensive! Loss of meat quality, injuries to
animals, animals may be condemned
Weight loss ..shrink
Pigs are very vulnerable to suffocation
Bruising –especially sheep and pigs
Immune stress / microbial shedding

Q

2 effects of stress on meat

A

Dark Firm Dry (DFD)
– PRE‐MORTEM depletion of muscle glycogen
2. Pale Soft Exudative (PSE)
– POSTMORTEM depletion of muscle glycogen

Q

normal post slaughter changes

A

Well fed un‐stressed animals should have a lot of glycogen in muscle before slaughter
After slaughter metabolism continues in muscle cells
Glycogen is converted to lactic acid which lowers the pH of muscle and tenderizes the meat

Q

DFD

A

Dark Firm Dry
Chronic Stress prior to slaughter + adrenaline= pre‐mortem glycogen depletion in muscles
reduction in lactic acid causes high pH

Q

PSE

A

Pale Soft Exudative
High stress pre‐slaughter (acute)
Rapid postmortem intracellular glycolysis causes accumulation of lactic acid

Q

True/False: there is heritable susceptibility to PSE

Q

antemortem inspection of livestock

A

Inspection of individual live animals prior to slaughter
Helps keep ill animals out of food chain
Helps reduce contamination of abattoir

Q

Public Health Veterinarian

A

Makes a DISPOSITION at inspection

20
Q

“subject”

A

Cow is bought by Slaughter Plant is “subject” to passing inspection at slaughter

21
Q

“suspect”

A

Public Health Vet’s disposition at antemortem inspection is “suspect”

  • history of recent illness
  • signs indicative of localized disease condition
22
Q

condemmed

A

signs indicative of generalized disease condition

23
Q

conditions resulting in condemnation

A
  • 4 D’s (dead, dying, diseased, disabled)
  • systemic infection
  • systemic metabolic conditions
  • when you can hold animal for possible recovery
24
Q

downer cattle

A

FSIS prohibits the slaughter of cattle that are not able to stand or walk
have a high probability of being infected with BSE

25
regulatory diseases
M. bovis | Brucellosis
26
reportable diseases
Meat inspection provides an additional opportunity for surveillance of animal diseases Reportable / notifiable diseases must, by law, be reported when detected at slaughter
27
slaughter is a 2 step process
stunning | exsanguination
28
humane slaughter
Livestock must be rendered insensible to pain before being shackled, hoisted, or cut
29
exception to humane slaughter
``` ritual slaughter (kosher, halal) -only for the stun before sticking part of the law ```
30
Kosher and Halal
Under Jewish and Islamic law, animals for slaughter must be healthy and uninjured at the time of death, which rules out driving a bolt into the brain
31
4 approved methods of stunnin
carbon dioxide electricity captive bolt firearms
32
electricity
Cattle (rare), calves, sheep, goats, swine Electrical current through brain sufficient to generate an epileptic seizure/stun animal Excessive amperage may cause petechial hemorrhages
33
carbon dioxide
Swine, sheep, and calves Must be sufficient to induce proper surgical anesthesia with minimum excitement Can be used for depopulation of pigs and chickens
34
captive bolt
Cattle, sheep, goats, swine penetrating and non penetrating proper restraint and placement
35
gunshot
Cattle, calves, sheep, goats, swine head and brain not suitable for food aim correctly
36
effective captive bolt
``` animal immediately collapses rigid with extended followed by involuntary kicking eyes central and fixed no corneal reflex no rhythmic breathing heart beat continues for some time ```
37
after stunning
rapidly moved to sticking | exsanguination typically used for killing
38
true/false: FSIS inspectors do have the right to immediately halt all slaughter at a plant in cases of “egregious” violations
TRUE
39
shackling
hang animal before sticking | increases volume of blood loss
40
sticking
cut all veins in neck brain death in 15-20 seconds 50% of total blood volume loss
41
chest sticking (pigs)
cut vessels where they arise from the heart | may be faster than throat cutting
42
what is the most common source of meat contamination
dressing: soil on hide, rumen contents, feces, etc
43
dressing carcass
``` skinned/dehided/ dehaired head removed eviscerated shrouded (cattle only) chilled ```
44
cattle dressing
``` skinning is mechanical head removal evisceration carcass is washed out with high pressure water shrouded (removed after 24hr chill) ```
45
swine dressing
carcass is washed dehairing (hide left on/ hair removed) head separation, evisceration, and cooling follow (generally by hand)
