How should food be stored to prevent contamination?

Storing food in clean, airtight containers is crucial for preventing contamination. Airtight containers protect food from exposure to airborne pathogens, pests, and environmental contaminants, such as dust and moisture. By sealing the food, these containers help maintain its freshness and reduce the risk of spoilage while also minimizing the chances of cross-contamination with other food items or substances.

Using clean containers is essential as well because any residual dirt or bacteria present on the container can transfer to the food, leading to foodborne illness. Airtight seals also help prevent the growth of mold and other microorganisms that thrive in moist environments.

In contrast, open containers expose food to various contaminants and environmental factors, which can compromise food safety. Similarly, metal cans and glass jars without lids do not provide the same level of protection as airtight containers, potentially allowing for contamination. Thus, the practice of using clean, airtight containers is the most effective method to safeguard food from contamination.
