What does open dating indicate on a perishable product?

Open dating on a perishable product specifically refers to information about the product's freshness or shelf life. This dating helps consumers understand how long the product will maintain its quality and safety for consumption. Manufacturers typically use words like "sell by," "use by," or "best if used by" to convey this information. These dates guide consumers in making informed decisions about food items, ensuring they purchase and consume products while they are still in good condition.

The other choices do not apply to open dating. The product's price is often indicated on the packaging or shelf, but it is not related to open dating. Information about ingredients is usually found on the nutritional label, rather than as a date. Lastly, manufacturer contact details are typically located on the packaging but are separate from any dating information. Thus, option B accurately captures the essence of what open dating signifies on perishable products.
