An opened package of uncooked bacon will generally last up to one week in the refrigerator if stored properly in an airtight container or tightly wrapped in foil or a zip-top bag

. Cooked bacon, once opened, can be safely stored in the fridge for about four to five days

. To maximize freshness after opening, keep bacon sealed tightly to minimize exposure to air and bacteria, which accelerate spoilage

. Signs that bacon has gone bad include discoloration (gray, green, or brown hues), a sour or sulfuric smell, sliminess, or visible mold-if any of these occur, the bacon should be discarded

. For longer storage, bacon can be frozen: raw bacon lasts up to six months unopened and about one month if opened and frozen properly; cooked bacon can be frozen for about one month as well

. In summary:

• Uncooked opened bacon in fridge: up to 1 week
• Cooked opened bacon in fridge: 4-5 days
• Frozen uncooked bacon: up to 6 months unopened, about 1 month opened
• Frozen cooked bacon: about 1 month

Always store bacon in airtight packaging to prolong shelf life and check for spoilage signs before use
