Summary

The survival and growth patterns of Listeria varied with the packaged product. Populations on packaged lettuce and swedes significantly increased during a 14-day storage period. During the same period, Listeria counts gradually decreased on coleslaw mix. Acid adaptation enhanced survival of Listeria spp. during storage in packages of vegetables which had relatively high in-pack CO2 levels. It is concluded from the tests that adapting listerial cells to mildly acidic conditions rendered cultures more resistant to relatively high (25-30%) CO2 atmospheres.
