Signs of Spoilage

- Bitter or stale taste
- Mold growth
- Shriveled or discolored appearance
Room Temperature Safety
40°F–140°F
While nuts are generally shelf-stable, once opened, especially if seasoned with oils, they should not be left at room temperature for more than 2 hours. Prolonged exposure to the danger zone can accelerate rancidity and spoilage.
Safe Handling
Always wash hands before and after handling nuts.
Keep nuts away from strong-smelling foods, as they can absorb odors.
Check for signs of rancidity before consuming, especially if stored for extended periods.
