Rapid Assessment of the Microbiological Quality of Poultry Carcasses Using ATP Bioluminescence

Abstract
The meat industry is in need of faster and more reliable methods to determine microbial loads in food products. A rapid method (r = 0.85, p < 0.001) and demonstrated good repeatability between replicates. It is envisaged that the modified ATP bioluminescence assay would best be used as a platform rejection test. Using threshold levels determined from the regression equation, the ATP bioluminescence assays gave about 90% agreement with plate counts for carcass rinses with counts above 5 × 104 CFU/ml. These findings suggest that the modified ATP bioluminescence assay could be used for monitoring critical control points (CCPs) in programs based on hazard analysis of critical control points (HACCP).
