Modified atmosphere killing has been used in the EU for over twenty-five years and is in use in the U.S. Among the major integrators, Perdue has led the field with retrofitting existing plants. New plants with modified atmosphere killing include the Bell and Evans and Lincoln Premium Poultry/Costco operations. In addition MAK is in operation at GMP Poultry in MN. and the Smart Chicken plant in NE. acquired by Tyson Foods.
Perdue has also introduced enrichments, outside access and daylight in broiler housing.
Modified atmosphere killing eliminates the most ergonomically challenging component of processing and will facilitate adoption of mechanical hanging.
