A package which allows for butchering and packaging of fresh red meat at a centralized facility is provided which includes a support member such as a tray for receiving and supporting the meat, a permeable film enclosing the meat and an impermeable film enclosing the permeable film which remains in place during distribution and is removed at retail.
