Room Temperature Safety
The 'danger zone' (40°F–140°F) is where bacteria multiply rapidly in perishable foods. While dried seeds have low water activity and are less susceptible to bacterial growth, prolonged exposure to these temperatures can accelerate rancidity and quality degradation.
For optimal quality and to prevent rancidity, shelled pumpkin seeds should be stored in a cool, dark, dry place. Avoid prolonged exposure to warm temperatures, direct sunlight, or high humidity.
Safe Handling
Always store shelled pumpkin seeds in airtight containers to prevent moisture absorption, rancidity, and pest infestation.
Keep away from direct sunlight and heat sources, which can accelerate spoilage.
Check for signs of spoilage before consumption.
