ANTIBACTERIAL ACTIVITY OF A SODIUM ACID PYROPHOSPHATE PRODUCT IN CHILLER WATER AGAINST SELECTED BACTERIA ON BROILER CARCASSES

Bactericidal activity of Brifisol K(TM) (a commercial blend of sodium acid pyrophosphate and orthophosphoric acid) (BK Ladenburg, Ladenburg, Germany) was evaluated during chilling of broiler carcasses. Brifisol K(TM) (1.5% at 1 degrees C for 60 min) significantly reduced Escheric hia coil, coliforms and aerobic plate counts (APC) on postchill broile rs and increased shelflife by 1 to 2 days when stored at 4.4 degrees C . Reductions in incidence and levels of Salmonella were directly relat ed to successful neutralization of the carcass rinse solutions. Effect ive neutralization of all phosphate applications, whether the treatmen t is alkaline or acidic-based, is extremely important for accurate qua ntification of bactericidal efficacy.
