What is the safest method for storing dry goods?

Storing dry goods in airtight containers in a cool, dry area is the safest method because it effectively prevents moisture and air from deteriorating the quality of the food. Moisture can lead to the growth of mold and bacteria, while exposure to air can result in oxidation, which decreases freshness and can lead to spoilage. Airtight containers limit the chances of pests getting into the food, further protecting its integrity. Maintaining a cool, dry environment is critical as both temperature and humidity control play significant roles in prolonging the shelf life of dry goods, ensuring that they remain safe to consume over time.

The other methods are less effective: storing in a cool, damp area invites moisture that can lead to spoilage, while plastic bags at room temperature do not provide effective barriers against air and pests. Open shelves expose food to elements that could compromise safety and quality, making them unsuitable for proper food storage.
