Leuconostoc pseudomesenteroides PCK18 reduced the counts of L. monocytogenes by 1.22 log cfu/g in chicken burgers under MAP after 24 d. Furthermore, a reduction of 1.16 log cfu/g in C. jejuni together with a delay in the growth of lactic acid bacteria was obtained in chicken legs inoculated with Bifidobacterium longum ssp. longum PCB133 and packaged under MAP after 9 d. The combination and concentration of gases in the MAP doubled the products’ shelf-life in comparison with air-packaged samples in both experiments. In conclusion, this study has shown the effectiveness of 2 protective culture strains against 2 foodborne pathogens, resulting in safer products with a longer shelf-life.
