Definition & Meaning of "expiration date"

What is an "expiration date"?

The expiration date, also known as the expiry date or use-by date, is the date printed on food packaging that indicates the last day on which the product is considered safe to consume or use. It is determined by the manufacturer based on factors such as the product's ingredients, packaging, and storage conditions. Consuming food past its expiration date may pose health risks due to potential spoilage, loss of nutrients, or growth of harmful bacteria. Therefore, it is important to check the expiration date before consuming or using food products and to follow storage instructions to ensure their safety and quality.
