Summary

The food-borne human pathogen L. monocytogenes survived and its populations increased on apple cv. Delicious slices at 10 or 20 °C in air or controlled atmospheres of 0.5% O2 and 15% CO2, but did not grow at 5 °C. The pathogen populations declined over time when grown in various concentrations of apple juice and the decline was greater as the concentration of the juice decreased. Populations of L. monocytogenes inoculated into decayed apple tissue continually increased on fruit decayed by G. cingulata but did not survive after 5 days on fruit decayed by P. expansum. Storage temperature, as well as the absence of postharvest pathogens such as G. cingulata, is important for maintaining the safety of fresh-cut apples.
