Q

What are the labeling requirements for meat?

A

Everything must be labeled

Readily visible
Number on stamp is unique to processing plan

Q

What is involved in the HACCPs effort to establish preventative measures with critical limits for each control point?

Q

How can the HACCP verify the system is working?

A

Oversight and testing

Q

When is federal meat inspection not required?

A

Slaughter of animals for your own consumption (not for sale)

Individuals that purchase meat out of US (not exceeding 50Lb) for own consumption

Retail dealers that DO NOT slaughter with >75% of sales to retail customers (still must meet health department standards)

Q

T/F: farmed deer and elk fall under Federal meat inspection rules?

A

False

Also rabbit and alligators are exempt –> follow rules of FDA

24
Q

Who regulates poultry sale and inspection?

A

Poultry product inspection act (PPIA)

25
What are issues involving animal transportation?
Expensive Loss of meat quality/animal injury Weight loss Pig suffocation Brushing Immune stress-> disease
26
If an animal is stressed in transportation, what are the two main outcomes for the meat?
1. Dark firm dry -> pre-mortem depletion of muscle glycogen 2. Pale soft exudative (PSE) - >post-mortem deletion of muscle glycogen
27
T/F: glycogen converted to lactic acid is a normal post slaughter carcass change?
True
28
Dark firm and dry meat results form what?
Pre marten glycogen depletion -> reduced lactic acid causing high pH Muscle fibers swell and tightly packed
29
How can you reduce the occurrence of dark firm and dry meat?
Ensure adequate muscle glycogen - feed prior to transport - water every 12hrs in transport Reduced glycogen consumption (reduce stress) -calm handing and no animal mixing Manage implants
30
Pale soft exudative pork results due to?
Postmortem glycolysis causing accumulation of lactic acid (low pH) High stress pre slaughter
31
What heritable condition increases susceptibility of pigs to pale soft exudative meat?
Porcine stress syndrome (PSS) -recessive gene= malignant hyperthermia and response to stress
32
T/F: all livestock offered for slaughter in an offical establishment shall be examined and inspected on the day of, and before slaughter
True
33
What is the purpose of antemortem inspection of livestock?
Helps keep ill animals out of the food chain | Helps reduce contamination of abattoir
34
What is the antemortem inspection procedure?
Observe at rest Observe in motion Normal or abnormal? (Take temp) Suspect and condemned animals are ear tagged
35
Who makes a disposition of animals at inspection
Public health veterinarian
36
The disposition of animals is directed by?
Meat and poultry inspection regulations
37
What is the difference between and animal that is subject and suspect
Subject -> slaughter is subject to passing inspection Suspect-> inspected and may be abnormal
38
If an normal animal has no history of recent illness or medications, is it passed/suspect/condemned?
Passed
39
If an animal is normal but has history of recent illness/medications, is it passed/suspect/condemned
Suspect
40
If a animal has clinical signs of a localized disease, is is passed/suspect/condemned ?
Suspect
41
If an animal has clinical signs indicative of generalized disease condition, is it passed/subject/condemned?
Condemned
42
What are the 4 D's that result in condemnation?
Dead, dying, diseased, disabled
43
What must occur if a cow have positive rxn to TB test?
It is suspect --> extra PM inspection TB tissues removed and remainder is passed for COOKING only
44
If a animal tests positive for brucellosis, is the meat safe?
Meat form cattle or pigs is considered safe NOT from goat --> must be destroyed
45
What are the two steps of humane slaughter?
Stunning | Exsangunation
46
What is the only exception to humane slaughter?
``` Ritual slaughter (kosher, halal) -> killed by exsanguintion ```
47
What are the 4 approved methods of stunning?
Carbon dioxide Electricity Captive bolt Firearm
48
What is electrical stunning?
Current through brain to generate seizure/stun
49
How CO2 used for slaughter ?
Induce surgical anesthesia with minimal excitement
50
What are the two captive bolt methods of stunning?
Penetrating - enter cranium Non penetrating- cause concussion (less brain contamination) --> must have proper aim for animal sp
51
If gunshot is used for stunning it must be?
Sufficient to render animal insensible Head and brain will not be suitable for food -> require correct aim
52
How can you tell if captive bolt/gun shot stunning was effective?
Animal immediately collapse Become rigid in forelimbs followed by involuntary kicking -> relaxation Eyes central and fixed No corneal reflex No rhythmic breathing Heart beat will continue for some time
53
Why is an animal shackled after exsangunation?
Increase volume of blood loss
54
What is "sticking" in meat processing?
Cut throat and all veins in neck Decrease time to death
55
What is "chest sticking"
In pigs Cut vessesl where they arise from the heart
56
What is the process of dressing a carcass?
``` Skinned Head removed Evicerated Shrouded (cattle only) Chilled ``` --> common source of meat contamination _> soil on hide or rumen contents/feces
57
What is shrouding in cattle?
Sheets in warm, mild brine => around carcass Shroud absorb blood Produce smooth, white, dense appearing fat Reduce collar shrinkage on lean animals
