How should open, bagged, dry food such as flour, rice, and sugar be stored?

in labeled, approved food containers with tight-fitting lids.

• Transfer them to airtight containers. Once the original packaging is opened, the food can start losing freshness. Airtight containers help keep out moisture, odors, and pests.
• Use food-grade plastic, glass, or metal containers with tight-fitting lids. Avoid reusing containers that previously held chemical products.
• If keeping in the original bag, push out excess air and seal tightly either by folding over the bag top tightly or using a clip or rubber band.
• Store in a cool, dry location away from sunlight and heat sources. Heat and moisture can cause the foods to spoil faster.
• For longer storage, choose containers that block out light which can degrade nutrients over time.
• Label containers with the contents and date so you use up the oldest items first.
• Regularly check for any moisture condensation inside the containers and discard if you see insects or spoilage.
