CassavaShelf Life, Storage, and Spoilage Guide
Pantry
1 week
Store whole, unpeeled cassava in a cool, dark, dry, and well-ventilated place, away from direct sunlight and moisture. Do not store in plastic bags as this can trap moisture and promote spoilage.
Refrigerator
Not RecommendedNot recommended for whole, unpeeled root
Whole, unpeeled cassava is generally not recommended for refrigeration as it can develop chilling injury, harden, and spoil quickly. If peeled and cut, it can be stored submerged in water in an airtight container in the refrigerator for up to 1 week, changing the water daily.
Freezer
10-12 months
To freeze, peel and cut cassava into desired pieces. Blanch in boiling water for 3-5 minutes, then immediately cool in ice water. Drain thoroughly, pat dry, and pack into airtight freezer bags or containers, removing as much air as possible.
Signs of Spoilage
- Soft spots or mushy texture
- Mold growth (white, green, or black fuzzy spots)
- Discoloration (dark spots or streaks, especially black or brown)
- Off-odor (sour or fermented smell)
- Hard, woody texture (can indicate spoilage or improper storage)
Room Temperature Safety
40°F–140°F
Cooked cassava should not be left at room temperature for more than 2 hours. If the ambient temperature is above 90°F (32°C), it should not be left out for more than 1 hour. Discard any cooked cassava left in the danger zone for too long.
Safe Handling
Cassava contains cyanogenic glycosides (cyanide precursors) and must always be peeled and thoroughly cooked before consumption to remove toxic compounds.
Never eat raw cassava.
Boil, bake, or fry cassava until it is very tender throughout to ensure it is fully cooked.
Wash hands, cutting boards, and utensils thoroughly with hot, soapy water after handling raw cassava to prevent cross-contamination.
Do not consume any part of the cassava plant other than the root.
