The fate of a toxigenic strain of Staphylococcus aureus in vacuum-packaged bacon.

Pork was cured by (a) the Wiltshire method and (b) a hygienic sweet cure process. Representative samples of both bacons were inoculated at ;low' density (10(3) organisms/g.) and ;high' density (10(6) organisms/g.) with a toxin-producing strain of Staphylococcus aureus, ;High' and ;low' density samples of both bacons were each stored at 5 degrees C. for 42 days and 15 degrees C. for 21 days.Results indicated that the test organism at high inoculum density grew slowly in both bacons at 5 degrees C. The organism survived at 5 degrees C. in both ;low density' bacons. At 15 degrees C. the test organism grew; growth being more pronounced in the ;hygienic' than in Wiltshire bacon.
