Room Temperature Safety
Not applicable to dry, shelf-stable flour. The danger zone (40°F–140°F) applies to perishable foods.
Store in a cool, dry place below 70°F (21°C) to maintain quality and prevent pest activity. Ensure packaging is sealed tightly after each use.
Safe Handling
Keep dry and sealed to prevent moisture absorption and pest infestation.
Use clean, dry utensils when scooping flour to avoid introducing contaminants.
If gluten-free status is critical, prevent cross-contamination with gluten-containing products.
