Abstract
A flow-through electrical treatment system was evaluated as a method to eliminate S typhimurium in poultryscalder water. The flow-through treatment system consisted of an inlet tank, a treatment cylinder, and an outlet tank. A dcpower supply provided electrical signals to platinum wire electrodes in the treatment cylinder. With 0.15 M NaCl added asan electrolyte, a 2-A electrical current was applied to poultry scalder water flowing through the treatment cylinder at a rateof 5 L/min. Residence time in the cylinder was 1.82 min. Samples were tested for salmonellae using standard platingmethods as well as pre-enrichment/enrichment techniques. All salmonellae were eliminated from the treated poultry scalderwater while the untreated scalder water contained large numbers of salmonellae.
