In order to evaluate the increase of L. monocytogenes concentration during home storage, a low level of the pathogen (<10 CFU/g) was inoculated in sliced ham. Two storage temperatures (5 °C and 9 °C) were selected from a previous study in 33 home refrigerators. Three days of storage or less were necessary to reach the regulated limited concentration (100 CFU/g), at both temperatures. When storage time was extended to 5 days, the pathogen achieved risky values (>10³ CFU/g).
