Signs of Spoilage
- Bitter or sour taste
- Off-odor (paint-like, chemical, or stale smell)

- Mold growth
- Shriveled appearance
Room Temperature Safety
The danger zone for food is between 40°F (4.4°C) and 140°F (60°C), where bacteria can multiply rapidly. While nuts are low-risk for bacterial growth, quality degrades faster in this range.
For best quality and to prevent rancidity, store crushed walnuts in the refrigerator or freezer, especially after opening or if not consumed within a short period.
Safe Handling
Always wash hands before and after handling food.
Prevent cross-contamination by keeping nuts separate from raw meats, poultry, and seafood.
If using in baking or cooking, ensure they are fresh and free from spoilage.
