A package which allows for butchering and packaging of fresh red meat at a centralized facility is provided which includes an impermeable tray (12) supporting the product, a first film (70) sealed to the tray for enclosing the product, means defined within the first film for exchanging gases into and out of the package, and a second impermeable film (68) enclosing the first film, such that removal of said impermeable film provides for the exchange of gases, into and out of the package. The means for exchanging gases may be perforations (72) defined within the first film, a second highly permeable film sealed to the first film, or an enlarged opening formed within the first film which is enclosed with a patch following adequate gas exchange at retail. Such gas exchange is required to release any low oxygen atmosphere and allow for the introduction of oxygen to the packaged meat product. Said means for exchanging gases having a gas transmission rate of at least about 50,000 cc/m2/24 hrs./atm. at 73.degree.F.
