Freezer

Sweet potatoes should be cooked or blanched before freezing. For best quality, mash, bake, or prepare in casseroles. Store in airtight containers or heavy-duty freezer bags.
Signs of Spoilage
- Soft spots or mushy texture
- Mold growth (fuzzy spots of any color)
- Significant discoloration or black spots
- Unpleasant or sour odor
- Excessive sprouting (while not always unsafe, indicates quality degradation)
Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).
Raw sweet potatoes are generally safe at room temperature for short periods, but for optimal quality and to prevent sprouting, store as recommended in the pantry section. Cooked sweet potatoes should be refrigerated promptly.
Safe Handling
Wash sweet potatoes thoroughly under running water before peeling or cooking.
Do not refrigerate raw sweet potatoes; store them in a cool, dark, well-ventilated area.
Cook sweet potatoes to a safe internal temperature and desired tenderness.
Avoid cross-contamination by using separate cutting boards and utensils for raw produce and raw meats.
