Attachment inhibition of meat spoilage organisms to meat
First Claim
1. The process of avoiding spoilage of freshly slaughtered meat comprising the steps offorming an aqueous solution of chlorine dioxide in a concentration of 0.04-1.0 ppm,said concentration being great enough to substantially inhibit the attachment of meat spoilage organisms to said meat andinsufficient to form with the meat detectable levels of organic chlorine,washing, with said solution, freshly killed meat carcasses within a time prior to substantial attachment of such meat spoilage organisms to said meat carcasses and thereafterintermittently applying said solution to said carcasses during chilling.

Abstract
A process for preventing attachment and growth of spoilage bacteria on the surface of freshly slaughtered meat carcasses utilizes substantially nontoxic concentrations of chlorine dioxide to inhibit the attachment of such bacteria without formation of detectable chlorinated organic compounds. The chlorine dioxide solution is applied as a low pressure spray immediately post-slaughter to prevent establishment of a bacterial load directly derived from the conditions of slaughter, and during the subsequent chill period to prevent substantial recontamination.

2. The process of avoiding spoilage of freshly slaughtered meat comprising the steps of
forming an aqueous solution of chlorine dioxide in a concentration of 0.04-1.0 ppm, said concentration being great enough to substantially inhibit the attachment of meat spoilage organisms to said meat and less than that which is substantially toxic to such meat spoilage organisms; -
washing, with said solution, freshly killed meat carcasses within a time prior to substantial attachment of such meat spoilage organisms to said meat carcasses, and thereafter intermittently applying said solution to said carcasses during chilling.

3. The process of avoiding spoilage of raw meat comprising the steps of
applying an aqueous solution of chlorine dioxide, in a concentration of 0.04-1.0 ppm, to the meat surfaces at a time substantially coincident with a contaminating event by meat spoilage microorganisms, said concentration being less than that which is toxic to such meat spoilage microorganisms and great enough to substantially inhibit their attachment to the meat surfaces whereby to prevent establishment of such meat spoilage microorganisms on said meat surfaces and substantially retard thereafter their secretion of slime, and thereafter applying such solution to said meat surfaces during cold storage.
