What happens to meat after slaughter?

The post-mortem changes that take place when muscle is converted into meat have a marked effect on the quality of the meat. After slaughter the glycogen in the muscle is converted into lactic acid causing a fall in pH from an initial value of pH 6.8 – 7.3 to about 5.4 – 5.8 at rigor mortis.

What do slaughterhouses do with remains?

Ranchers, butchers, and slaughterhouses have traditionally sent carcass remains to rendering plants. coli intensifies with rainfall and oozes for decades after burial (it can take 25 years for carcasses to decompose).

About 60 percent of it—offal, bones, tendons, blood, and plasma—becomes abattoir waste and, as such, has to be either recycled or disposed of. Ranchers, butchers, and slaughterhouses have traditionally sent carcass remains to rendering plants.
