The freezer is an excellent tool for preserving food and leftovers, but even frozen items are limited. If something in your freezer looks questionable, don’t take chances—throw it out. Bacteria can survive in freezing conditions, and consuming old frozen food could pose serious health risks.
Frozen food past its recommended storage period should be discarded, even if it appears fine.
Here are some general guidelines: fish and seafood can last up to 3 months; cooked fish, 1 month; processed foods like ham, bacon, and hot dogs, 2 months; raw meat, up to 1 year; and cooked meat, 3 months. Beyond these time frames, food quality declines significantly, and the risk of spoilage increases.
Always store leftovers in airtight containers or tightly wrap them to prevent moisture loss. Without proper sealing, food can dry out and lose its flavor. If you notice ice crystals covering the food, this may indicate spoilage. When in doubt, throw it out.
Divide food into individual portions before freezing. This minimizes the risk of contamination when taking out small servings and reduces waste.
While freezing slows bacterial growth, it doesn’t eliminate it. Opening the freezer frequently can introduce contamination, and specific pathogens, like norovirus, can survive at low temperatures.
According to the FDA, norovirus can remain active in ice for extended periods—99% survive after 3 days, and 45% remain viable after 17 days. To prevent infection, over 99.9% of the virus must be eliminated.
To avoid cross-contamination, store different food types in separate storage areas. For example, store processed or cooked items on the upper shelves and raw meats or seafood on the lower shelves.
Finally, to ensure food safety and quality, maintain a freezer temperature of 0°F (-18°C) or lower.
