Low-Oxygen Packaging of Fresh Meat with Carbon monoxide: Meat Quality, Microbiology, and Safety
AMSA White Paper Series
American Meat Science Association
Fresh retail meats in the United States commonly are packaged using either polyvinyl chloride (PVC) film or modified atmosphere packaging (MAP). Since 2002, carbon monoxide (CO) has been permitted as a MAP gas for use during distribution in the United States (Rulis, 2002). In 2004, CO was further permitted at low levels as a MAP gas in retail fresh meat packaging (Tarantino, 2004). Although use of CO in meat packaging applications is relatively new in the United States, meat products have been exposed to CO as a component of wood smoke for decades. CO also has been used in the United States since the 1970s as a modified atmosphere gas component for shelf life extension of iceberg lettuce during distribution (Mermelstein, 1977; Kader, 1983) and is recommended as a component of modified atmospheres to prolong shelf life of tomatoes, cauliflower, cantaloupe, citrus, and strawberries (Wolfe, 1980).
