Room Temperature Safety
Not applicable to dry cereal. The danger zone (40°F–140°F) applies to perishable foods, such as cereal prepared with milk.
Dry cereal is shelf-stable and does not require refrigeration. Store in a cool, dry place. If cereal is prepared with milk, it should not be left at room temperature for more than 2 hours (1 hour if the temperature is above 90°F/32°C).
Safe Handling
Always store dry cereal in a cool, dry place away from direct sunlight and heat.
After opening, transfer cereal to an airtight container or ensure the original packaging is tightly sealed to prevent moisture absorption and pest entry.
Check for signs of pests before consumption, especially if stored for extended periods.
