Section: claims

1. A method of providing fresh meat products, comprising:irradiating the meat products in a first controlled atmosphere;packaging the irradiated meat products downstream from the irradiation area in a second controlled atmosphere having a modified oxygen concentration; and distributing the packaged irradiated meat products to a retail store; wherein the first controlled atmosphere excludes oxygen. 2. The method of claim 1, wherein the second controlled atmosphere is high in oxygen. 3. The method of claim 1, wherein the steps of irradiating the meat products in the first controlled atmosphere and packaging the irradiated meat products in the second controlled atmosphere are performed in the same meat packing facility. 4. The method of claim 1, further comprising:adding an antioxidant to the meat products prior to the step of irradiating the meat products in the first controlled atmosphere. 5. The method of claim 4, wherein the antioxidant is a rosemary extract. 6. The method of claim 4, wherein the package irradiated meat products have a color-life of over three weeks. 7. The method of claim 6, wherein the retail store is a convenience store. 8. The method of claim 1, further comprising:topically applying an antioxidant to the irradiated meat products prior to the step of packaging the irradiated meat products in the second controlled atmosphere. 9. The method of claim 8, wherein the antioxidant is a rosemary extract. 10. The method of claim 8, wherein the packaged irradiated meat products have a shelf-life and a color-life of over three weeks. 11. The method of claim 10, wherein the retail store is a convenience store. 12. The method of claim 1, wherein the retail store is a superstore that does not include an in-store meat processing department. 13. The method of claim 1, further comprising:providing a clean curtain between a meat processing area where the step of irradiating meat products is performed and a meat packaging area where the step of packaging the irradiated meat products is performed. 14. The method of claim 1, wherein the step of irradiating meat products is performed in a sealed conduit having the first controlled atmosphere therein. 15. The method of claim 14, wherein the step of irradiating meat products comprises:conveying the meat products to be irradiated through a processing area in the sealed conduit;controlling the first controlled atmosphere in the sealed conduit to be different from an ambient atmosphere; andapplying radiation to the meat products in the processing area. 16. The method of claim 15, wherein the first controlled atmosphere in the sealed conduit excludes oxygen. 17. The method of claim 16, wherein controlling the first controlled atmosphere in the sealed conduit comprises filling the sealed conduit with a gas selected from the group consisting of nitrogen and carbon dioxide.
