Other foods have been treated with the broad-host-range bacteriophages A511 and P100 for control of L. monocytogenes strains Scott A (serovar 4b) and WSLC 1001 (serovar 1/2a) (Guenther et al., 2009). In liquid foods, such as chocolate milk and mozzarella cheese brine, bacterial counts rapidly dropped below the level of direct detection. In solid foods, according to the authors, the bacte- riophages were able to reduce bacterial counts by up to five log units. The authors also considered the application of more bacteriophage particles (3 108 pfu/g) to be more effective than lower doses.
