showed a statistically significant reduction (p < 0.001) of
L. monocytogenes by over 99% in the ListShield™ treated samples
compared to the PBS treated control samples (Fig. 1C). While
freezing has been shown to reduce the levels of L. monocytogenes in
various foods, regrowth of the pathogen can occur once the foods
are thawed. In that context, our data suggest that application of
bacteriophages may further reduce the levels of L. monocytogenes in
foods frequently subjected to varying storage conditions, increasing
their safety during periods of prolonged storage at temperatures
that promote L. monocytogenes growth.
