A method of processing meat is described. Embodiments of the method include treating a surface of intact meat while leaving a portion of an interior of the piece of intact meat uncooked. Surface treatment can reduce microorganism abundance on the surface. The surface-treated intact meat is subsequently ground. Surface-treatment includes, but is not limited to, heating the surface, irradiating the surface with ionizing or non-ionizing radiation, or treating the surface with an antimicrobial chemical. The surface-treatment prevents or reduces infusing microorganisms throughout the ground meat during grinding, resulting in ground meat that is safe for human consumption without being thoroughly cooked. Accordingly, hamburger or other ground meat can be served rare or otherwise undercooked and be safe for human consumption.
