Signs of Spoilage
- Rancid or bitter taste
- Stale or 'paint-like' odor
- Mold growth (fuzzy spots, discoloration)
- Shriveled or discolored appearance
- Soft or rubbery texture (should be firm and crisp)
Room Temperature Safety
40°F–140°F (4°C–60°C). While nuts are not typically a TCS (Time/Temperature Control for Safety) food, prolonged exposure to warm temperatures can accelerate rancidity and mold growth.
For best quality and to prevent rancidity, store nuts in a cool, dry place or refrigerate/freeze for longer storage. Do not leave shelled nuts exposed to air at warm room temperatures for extended periods.
Safe Handling
Always wash hands before and after handling nuts.
Keep nuts dry to prevent mold growth.
Check for signs of rancidity (bitter taste, off odor) before consumption.
Avoid cross-contamination with allergens if preparing for individuals with nut allergies.
