- Abstract
- Inactivation rates of Salmonella enteritidis in vitro and in vivo were assessed using confocal microscopy and flow
cytometry. S. enteritidis was inactivated with 1% (w/v) trisodium phosphate (TSP) and live cells, and inactive cells were
distinguished by staining with fluorescent probe, LIVE/DEAD BacLight Bacteria Viability stain. After TSP treatment for 1 min,
most of Salmonella cells changed from green (live cells) fluorescence to red (inactive cells) fluorescence, indication of effective
sanitizing. Inactivation efficiency and contamination sites of S. enteritidis on chicken skin by TSP treatment were assessed using
confocal laser microscopy. Precise flow cytometry histograms for viability changes of S. enteritidis after TSP treatments were
obtained. Efficiency of various sanitizer treatments on foodborne pathogens could be assessed using this method.
