Which item should never be reused for food storage?

Single-use containers, such as take-out boxes, are specifically designed for short-term use and are made from materials that may not be safe for repeated exposure to food. These containers can become contaminated with bacteria or other pathogens after their initial use. Furthermore, the materials they are made from might not be durable enough to withstand multiple cleanings, potentially leading to the leaching of harmful substances into food or causing physical contamination.

In contrast, glass jars, plastic food containers, and reusable bags are typically built for multiple uses and can be safely cleaned and sanitized for food storage. Glass jars, for example, can be reused many times without degrading, and plastic containers, if made for food storage, are designed to be washed and reused safely. Similarly, reusable bags, when properly cleaned, can also be utilized multiple times without an increase in health risks.
