controlled-atmosphere killing
n.— «Our proposal requests only a feasibility study concerning a new slaughter technology called controlled-atmosphere killing (CAK), which is used in 30 plants in Europe and five in the U.S. I have a long list of quotes from plants endorsing this technology. It is win-win for everyone—animals, plant employees, and especially the company and shareholders.…With CAK, birds are moved directly from transport trucks to chambers without ever leaving their crates. The oxygen in the air that they are breathing is replaced with nontoxic gases, slowly and gently putting the birds “to sleep.” CAK is a win for the workers who have to work in very unpleasant environments handling thousands of panicked birds.» —“Group Calls for Less Cruel, More Profitable Slaughter System” in Springdale, Arkansas Peta Media Center Feb. 1, 2007.
