Karage FlourShelf Life, Storage, and Spoilage Guide
Pantry
6-12 months
Store in a cool, dry, dark place in an airtight container to prevent moisture absorption and pest infestation.
Refrigerator
1 year
Store in an airtight container to prevent moisture absorption and odors from other foods. This can extend shelf life, especially for specialty flours.

Signs of Spoilage
- Off odor (rancid, musty)
- Mold growth
- Presence of insects or larvae

Room Temperature Safety
40°F–140°F
While dry flour is not subject to rapid bacterial growth like perishable foods, exposure to high humidity and temperatures can lead to mold or insect infestation. Always keep dry flour in a cool, dry place. Discard if exposed to moisture or pests.
Safe Handling
Do not consume raw flour. Flour is a raw agricultural product and may contain harmful bacteria (e.g., E. coli). Always cook or bake flour thoroughly.
Keep flour dry to prevent mold growth and insect infestation.
Avoid cross-contamination by storing flour away from raw meats, poultry, and seafood.
Wash hands thoroughly after handling raw flour.
