Briefly, for each sample, one randomly selected post-chiller whole young chicken carcass was aseptically placed into a sterile bag and shaken with 400 ml pre-chilled Buffered Peptone Water (BPW).
Once the contents of the bag were properly mixed, two sterile screw-cap containers with lids were each filled with 100 ml of rinse fluid, i.e. a total of 200 ml rinse was submitted for analysis.
