Controlled Atmosphere Stunning

Carbon dioxide controlled atmosphere stunning

Controlling the harvesting process


At Linde, we have years of industry leading experience in the use and handling of carbon dioxide for food processing. And we’ve used what we’ve learned to develop our new controlled atmosphere stunning systems for both turkey and broiler processing. 

Each of our systems employs a multi-step cycling of carbon dioxide to render caged birds inactive. The three guiding objectives of the Controlled Atmosphere Stunning process are to: 

  1. Anesthetize the birds with minimal aversive reaction to the change in CO2 levels

  2. Immobilize birds to avoid wing flapping; reducing injury to both birds and workers

  3. Desensitize birds to ensure they do not regain consciousness during processing
