Bactericidal activity of Brifisol K (a commercial blend of sodium acid pyrophosphate and orthophosphoric acid) (BK Ladenburg, Ladenburg, Germany) was evaluated during chilling of broiler carcasses. Brifisol K (1.5% at 1°C for 60 min) significantly reduced Escherichia coli, coliforms and aerobic plate counts (APC) on postchill broilers and increased shelflife by 1 to 2 days when stored at 4.4°C. Reductions in incidence and levels of Salmonella were directly related to successful neutralization of the carcass rinse solutions. Effective neutralization of all phosphate applications, whether the treatment is alkaline or acidic based, is extremely important for accurate quantification of bactericidal efficacy.
