How are animals stunned prior to slaughter?

Electrical stunning is done by sending an electric current through the brain and/or heart of the animal before slaughter. Current passing through the brain induces an immediate but non-fatal general convulsion that produces unconsciousness.

How are pigs stunned with CO2 before slaughter?

Carbon dioxide gas is used to induce unconsciousness. As the animal inhales the carbon dioxide gas, blood oxygen level decreases resulting in a loss of brain function and eventual brain death.

Does animals feel pain when slaughtered halal?

Minimally painful and complete bleeding is required during halal slaughter, which is difficult to perform in large animals [69]. Previous researchers have indicated an association between the location of the cut and the onset of unconsciousness during slaughter without stunning, such as in halal slaughter.

How is gas used to stun pigs?

The gas is used for a more 'humane' method of slaughtering the pigs. They are taken into a CO2 chamber. As the effects of CO2 are reversible, the time between stunning them and them being drained of their bodily fluids should be quick so they don't regain consciousness before the slaughtering begins.

How do they stun pigs with carbon dioxide?

Social animals

Pigs are stunned using a 70% to 90% carbon dioxide concentrate. They are typically loaded in groups of about half a dozen onto something like a paternoster lift, which lowers them gradually into ever higher concentrations of the gas.

Are gassing chickens humane?

High carbon dioxide gas concentrations are aversive to poultry and can lead to hyperventilation, breathlessness, and suffocation.

What do slaughterhouses do with guts?

A final, and by far the most hopeful, option is the anaerobic digestion of slaughterhouse waste. Anaerobic digestion generates biogas (a mixture of carbon dioxide and methane that can be converted into usable energy) and sludge (which can be used as a fertilizer).

What really happens in a slaughterhouse?

At a slaughterhouse, you have big animals entering at one end, and small cuts of meat leaving at the other end. In between are hundreds of workers, mainly using handheld knives, processing the meat. So during that whole production system, there are many opportunities for the meat to be contaminated.
