Antibacterial Efficacy of Electrochemically Activated Solution for Poultry Spraying and Chilling

An electrochemically activated solution (EAS) was evaluated for its antibacterial efficacy against Salmonella typhimurium on chicken carcasses during inside/outside (I/O) birdwasher spraying at 20°C and 413 kPa for 17s and chilling at 4°C for 45 min in a pilot plant. The EAS with 50 ppm of oxidants in terms of free chlorine (CI) in the I/O spray reduced Salmonella on carcasses by 1.39 log₁₀ CFU/carcass, whereas tap water and a 50 ppm (CI) hypochlorite solution reduced Salmonella by 0.86 and 0.87 log₁₀ CFU/carcass, respectively. Further chilling using iced EAS (50 ppm of CI) did not reduce Salmonella on carcasses but eliminated Salmonella in the chiller water.
