Federal meat inspection act (FMIA) requires
- inspection of all meat sold from livestock

- Poultry! (covered by PPIA)
- farmed deep, elf, rabbits, alligators, etc.
Stress associated with transport
- weight loss
- suffocation
- bruising
- immune stress/ microbial shedding
Two stress effects on meat
- Dark firm dry (DFD): pre-mortem. More commen in cattle
- Pale soft exudative (PSE): postmortem. More commen in swine
What happens in normal muscle post slaughter?
Glycogen is converted to lactic acid which lowers the pH of muscle and tenderizes the meat
Dark firm dry meat
- Chronic stress
- reduction in lactic acid causes high pH
Pale soft exudative pork
- high stress pre-slaughter
- postmortem intracellular glycolysis causes accumulation of lactic acid
- Condem at postmortem inspection
Porcine stress syndrome
- heritable susceptibility to PSE
- recessive gene related to malignant hyperthermia
When is antemortem inspection done?
On the day of and the day before slaughter
Purpose of antemortem inspection
- helps keep ill animals out of food chain
- helps reduce contamination of abattoir
Inspection procedure
