The controlled atmosphere stunning system uses a multi-stage, carbon dioxide atmosphere process.
This is often the most reliable slaughter method for ensuring consistency in terms of good welfare and quality.
The carbon dioxide completely stuns and desensitises animals before slaughter, reducing stress.

To ensure the well-being of the animal, it is required that the killing methods are not painful and spare the poultry and pigs from any avoidable pain or stress. This means stunning the animals prior to slaughter.
The multi-stage Controlled Atmosphere Stunning process has several welfare advantages.
Handling stress is reduced because live chickens no longer have to be hung on shackles. Another welfare advantage is that the chickens will be rendered insensible before shackling and bleeding. CO2 is used in the pig stunning process, pigs are conveyed in pits where the atmosphere is saturated with carbon dioxide.
When slaughtering chickens or turkeys for human consumption, it is imperative for ethical reasons, to ensure the well-being of the animal. Increasingly, carbon dioxide is being used for the stunning and killing of pigs. This is often the most reliable slaughter method to ensuring consistency in terms of good welfare and quality.
