Room Temperature Safety

For cooked oats: Follow the 2-hour rule (1 hour if ambient temperature is above 90°F/32°C). Dry, uncooked oats are shelf-stable and this rule does not apply to their initial storage.

40°F–140°F (for cooked oats)

Cooked oats should be refrigerated within 2 hours of cooking. Discard cooked oats left at room temperature for longer than 2 hours. Dry oats should be stored in a cool, dry place away from direct sunlight and heat sources.
