How should dry goods be stored to prevent pest infestation?

• A. In open containers in a cool place
• B. In airtight containers in a cool, dry place
• C. In plastic bags
• D. In cardboard boxes

Answer: (B)

Storing dry goods in airtight containers in a cool, dry place is the best practice to prevent pest infestation. Airtight containers create a barrier that prevents pests, such as insects and rodents, from accessing the food. This is crucial because pests are often attracted to food resources, and by sealing them away effectively, the risk of infestation is significantly reduced.

Additionally, keeping the food in a cool and dry environment further inhibits pest attraction. Warm and humid conditions can encourage the presence of pests and can also lead to spoilage of the food. Therefore, optimal storage conditions that combine both an airtight seal and appropriate environmental factors serve to maximize food safety and minimize the threat of pests.

Other methods, such as using open containers, plastic bags, or cardboard boxes, do not provide the same level of protection. Open containers allow pests to easily reach the food, while plastic bags and cardboard boxes can be penetrated by insects and may not keep out pests effectively, thereby increasing the risk of infestation.
