In the United States, products typically have either a "use by" date or a "best before" date, depending on the type of product. The use of these dates is not mandatory for all products, but they are often included voluntarily by manufacturers for various reasons.
The main purpose of these dates is to provide consumers with information about the quality and freshness of the product and to ensure food safety. Here's why US products may have these date labels:
Food Safety: Perishable products like dairy, meat, and certain prepared foods can pose a risk of foodborne illness if consumed after they have spoiled. By including a "use by" date, manufacturers can help consumers identify when a product is no longer safe to eat.
Product Quality: For many non-perishable items, such as canned goods and dry goods, a "best before" date is used. This date indicates the period during which the product is expected to be at its peak quality, such as taste, texture, and nutritional value. While consuming products after this date is generally safe, they may not be as fresh or flavorful.
Legal Requirements: Some products, especially those regulated by the US Food and Drug Administration (FDA), may be required to have specific date labels for food safety reasons.
Consumer Expectations: Consumers often appreciate having clear information about a product's freshness and quality. Including date labels can enhance consumer trust and help them make informed decisions about their purchases.
It's important to note that not all products require date labels, and the specific terminology (e.g., "use by," "best before," "sell by") and format of date labeling can vary by state and product type. Additionally, some products, like certain medications or supplements, may have different types of date information to indicate expiration or potency.
Overall, while the use of date labels is common in the US, it is not a legal requirement for all products. Consumers should use their judgment and common sense when evaluating the safety and quality of products, especially those without date labels. When in doubt, it's always best to follow storage instructions and dispose of products that show signs of spoilage or deterioration.
