Room Temperature Safety
The danger zone (40°F–140°F) applies to perishable foods. Dry corn is shelf-stable.
Store dry corn in a cool, dry place below 70°F (21°C) to maintain quality and prevent pest infestation. Once cooked or rehydrated, follow perishable food guidelines and refrigerate promptly.
Safe Handling
Keep dry corn in sealed, airtight containers to prevent pest infestation and moisture absorption.
Inspect dry corn for any signs of mold, off-odors, or insect activity before use.
If rehydrating dry corn, use clean water and ensure it is cooked thoroughly to the appropriate internal temperature if part of a dish.
