Inhibition of Listeria monocytogenes in Cooked Ham by Virulent Bacteriophages and Protective Cultures

摘要

Protective cultures can be used successfully as an additional hurdle together with phages to reduce growth of Listeria monocytogenes on sliced cooked ham. Addition of phages resulted in a rapid 10-fold reduction of L. monocytogenes. After 14 to 28 days of storage, a 100-fold reduction was observed in samples with phages and protective culture compared to results for samples with phages alone.
