Abstract: Fluid distribution systems for use in meat-handling facilities include a fluid distribution assembly for fluidly coupling with a fluid supply where the fluid distribution assembly comprises at least one valve for alternately supplying fluid to a first nozzle assembly and a second nozzle assembly. The fluid distribution assembly may further include at least one motor for oscillating the nozzle assemblies. Cabinet assemblies for use in meat-handling facilities may include a fluid distribution system. Valve assemblies may include a diverter for selectively supplying fluid to at least two outlets. Methods of washing at least a portion of a carcass include spraying fluid onto the at least a portion of the carcass with a first set of nozzle assemblies and with a second set of nozzle assemblies positioned over the first set of nozzle assemblies.

Abstract: A swivel body for a packing house washer which includes a hollow housing, a ball joint mounted on a water line coupler which is mounted into the hollow swivel body. The waterline coupler has a hollow neck which is in fluid communication with the swivel body chamber. Water is forced into the swivel body chamber and passes through the waterline coupler into a spray bar. The ball joint fastened to the coupler and neck allows the waterline coupler to articulate within the swivel body. Bushings are used for water tight fitting of the ball joint within the housing.

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: A method for processing tripe includes refining tripe with at least one bleaching agent and at least one alkaline material to improve tripe appearance, and contacting the treated tripe with an alkaline builder at a temperature of about 110° F. to 160° F. Tripe may be rinsed with cold water before packaging. The methods of processing tripe may provide tripe with enhanced appearance appealing to consumers, while increasing margin profits to meat packing plants due to higher tripe yield and lower operation cost.
