Monitoring CO2 Concentrations In Pig and Poultry Processing
Carbon Dioxide stunning, otherwise known as controlled atmospheric stunning, involves using an environment with a high carbon dioxide (CO2) concentration to cause the animal to become unconscious. For gas stunning or slaughter to cause minimal harm to the welfare of the animal, it is crucial to use the correct CO2 concentrations. Insufficient CO2 concentrations mean that the livestock remain alert and conscious and if the CO2 concentration is too high relative to the O2 concentration at the beginning of the process, then pigs have been reported to show some signs of distress.
