IVD products that are expiration dated will have the expiration date found on the product labels.When dating is indicated by month and year only and no specific date is otherwise stated on the label or elsewhere, the product is expected to meet specifications until the last day of the month.Shelf life is the recommended maximum time for which products or fresh (harvested) produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected (or specified) conditions of distribution, storage and display. High-acid canned foods (tomatoes, fruits) will keep their best quality for 12 to 18 months; low-acid canned foods (meats, vegetables) for 2 to 5 years. A product that has passed its shelf life might still be safe, but quality is no longer guaranteed.According to the USDA, "canned foods are safe indefinitely as long as they are not exposed to freezing temperatures, or temperatures above 90 °F (32.2° C)". In most food stores, waste is minimized by using stock rotation, which involves moving products with the earliest sell by date from the warehouse to the sales area, and then to the front of the shelf, so that most shoppers will pick them up first and thus they are likely to be sold before the end of their shelf life."Best if Used By" is a type of date you might find on a meat, poultry, or egg product label. Does it mean the product will be unsafe to use after that date?
Shelf life depends on the degradation mechanism of the specific product.
The Recommended Retest Date for individual lots may be extended subject to quality review.
If extended, a new Date Retested and Recommended Retest Date will be published on the Certificate of Analysis.
To comply, a calendar date must express both the month and day of the month.
In the case of shelf-stable and frozen products, the year must also be displayed.
