CassavaShelf Life, Storage, and Spoilage Guide
Pantry
3-7 days
Store whole, unpeeled cassava in a cool, dark, dry, and well-ventilated area. Do not store in the refrigerator before peeling and cooking, as it can cause discoloration and hardening.
Refrigerator
Not recommended for whole, unpeeled; 2-3 days for peeled and submerged in water
Whole, unpeeled cassava is generally not recommended for refrigeration as it can develop cold injury, browning, and hardening. If peeled and cut, store submerged in cold water in an airtight container and change water daily.
Freezer
10-12 months
To freeze, peel and cut cassava into desired pieces. Blanch in boiling water for 3-5 minutes, then cool rapidly in ice water. Drain thoroughly, pat dry, and pack in airtight freezer bags or containers, removing as much air as possible.
Signs of Spoilage
- Soft spots or mushy texture
- Mold growth (fuzzy white, green, or black spots)
- Discoloration, especially black streaks or spots on the flesh
- Unpleasant or sour odor
Room Temperature Safety
40°F–140°F
Do not leave raw cassava at room temperature for more than 2 hours. If the ambient temperature is above 90°F (32°C), do not leave out for more than 1 hour, as bacteria can multiply rapidly in the danger zone.
Safe Handling
Raw cassava contains cyanogenic glycosides, which are toxic. It must be properly peeled and thoroughly cooked (boiled, baked, or fried) before consumption to remove these compounds.
Always wash hands with soap and water before and after handling raw cassava.
Use separate cutting boards and utensils for raw cassava to prevent cross-contamination with other foods.
Ensure cassava is cooked until very tender throughout to ensure safety.
