Methods and related apparatus for improving the efficacy of antimicrobial agents within processing tanks. Processing tanks can include side streams for introducing antimicrobial agents into the processing tanks. The antimicrobial agents will be added and mixed in the side stream to form a processing solution. Additional actions can be conducted on the processing solution within the side stream including any and or all of heating, pumping, sampling, measuring, testing and pH adjustment of the processing solution. The processing solution is divided into at least two processing solution steams, which can be introduced at two different and distinct locations within the processing tank such as a carcass introduction end and a carcass removal end. By simultaneously introducing at least two processing solution streams at different locations of the processing tank, large concentration gradients of the antimicrobial agent are avoided.

A chiller bath includes a tank for holding a volume of chiller water; a dosing system for dosing a first solution and a second solution into the chiller water, arranged to create a plurality of zones within the volume of water, wherein each zone has a higher concentration of either the first or the second solution than surrounding portions of the volume of water; and a meat or poultry immersion arrangement for immersing and moving carcasses in the chiller water. A method for reducing bacterial load on meat or poultry includes generating a plurality of zones within a chiller bath containing water by dosing a source of alkalinity and antimicrobial into the water, wherein the plurality of zones comprises at least one alkaline zone with a pH above 8.5, and at least one antimicrobial zone with pH below 8.5; and submersing meat or poultry in the bath. The zones can also be generated using spray nozzles in a meat or poultry operation.

The present invention has demonstrated that microorganisms present in a liver can be killed by washing the bile duct and the portal vein with hot water, and then disinfecting the liver using a chlorine-based disinfectant. It has also been demonstrated that sterilizing effects can be enhanced by freezing the liver after disinfection with a chlorine-based disinfectant.

A system and method for making a jerky meat product may include a pump to pump heated brine at a positive pressure at a desired temperature. Embodiments may also include an injector coupled to the pump to receive the heated brine and inject the heated brine into a cool meat product to elevate the meat product temperature. Embodiments may include a slicer that receives the meat product after the heated brine is injected and slices the meat product to a first thickness. A topical applicator may apply a topical application to coat an exterior of the slices and a flattener may flatten the slices to a second thickness less than the first thickness and to cause the topical application to adhere to the slices. Embodiments may further include a drying oven and/or grill to dry the slices of the second thickness to a desired moisture level.
