Abstract: A method for reducing the incidence of Salmonella in harvested meat comprising treating the meat with an effective electrostatically charged antimicrobial solution comprising a blend of lactic and citric acids in proportions containing a predominance of lactic acid from 65:5 wt./wt. to 77:3 wt./wt. lactic acid to citric acid; and the pH of the solution is less than about 3.2.

Abstract: Disclosed are methods for killing or reducing the incidence of pathogenic bacteria, comprising contacting the bacteria with a PURAC CL 21/80 solution (1-2.5% by weight) comprising lactic acid in an amount ranging from about 0.43% to 1.23% by weight and citric acid in an amount ranging from about 0.29% to about 0.88% by weight. In some aspects, the pathogenic bacteria can be present on a meat product.

Abstract: A method of recycling salt from a used brine solution for curing animal hides includes adjusting a pH level of the used brine solution to between about 6 and 12. The method includes introducing an oxidizing agent into the used brine solution in an amount to have a concentration between about 5 ppm and 600 ppm therein. The method includes allowing the oxidation of the used brine solution for a duration and removing solid organic materials from a surface of the used brine solution.

Abstract: A method for reducing the incidence of E. coli and Salmonella in slaughtered beef or other meat during processing or post-processing by treating the meat with an effective antimicrobial solution comprising lactic acid and a water soluble anionic or zwitterionic surfactant at a pH of about 3.2 or less. Mixtures of lactic acid with citric acid and a surfactant may also be employed. Antimicrobial solutions of lactic acid and surfactant may be used in other food processing applications.

Abstract: An improved lubricant for use with a conveyor in a meat packing plant meeting the requirements of (1) adequate lubricity, (2) “drip-resistance,” (3) safety, (4) rust resistance, (5) economy of manufacture and use, and (6) the ability to be removed by cleaning methods is provided by preparing a mixture of mineral oil, a fatty acid, a silicone oil, and a polybutene, each being acceptable for incidental contact with food, in certain minimum amounts and increasing the amounts of one or more of said components such that the improved lubricant has a viscosity of 20-160 centipoise. A method of improving a lubricant for use on a conveyor in a meat packing plant and a method of lubricating the conveyor are also disclosed.

Abstract: A method for cleaning used storage or processing liquid containers employing an aqueous solution of phosphoric acid, nitric acid and one or more surfactants, e.g., a detergent and/or wetting agent. Preferably, the aqueous cleaning solution has a total nitric acid content of 12 wt % or less. Complete cleaning can be achieved without using any caustic. The cleaning solution can be recycled repeatedly to clean multiple containers on numerous occasions over a period of time, e.g., several weeks.
