Salami can be frozen for two to three months. Unopened salami can be stored in the refrigerator for up to six months. Opened or sliced salami stays good in the refrigerator for two to three weeks.
The best way to freeze salami is by storing it in an airtight container. Salami should be frozen by the "sell by" date located on the packaging. Refrigerated salami can also be placed in an airtight container to keep out contaminants and moisture. Before consuming salami, always check for freshness. Typically, bad salami appears gray or brown around the edges and may give off a sour odor.
