Eastern Research Group, under contract with FDA, conducted this study of food product open dates. The information in this study was sought through literature reviews, multiple in-store surveys of food products and discussions with industry personnel and trade organizations. The survey universe consists of 149 product categories covering baked, dairy, frozen, refrigerated, shelf-stable, and chilled ready to eat food products.
In addition to examining the current regulatory and industry framework under which U.S.food manufacturers currently operate, this study also provides quantitative information on the current practices on different types of food labeling in the United States. Furthermore, the study includes a comprehensive analysis of industry practices on shelf life testing and decision criteria used in open dating to better qualify the observed results and to further evaluate the potential consequences of adding or modifying open dates on food products.
The last section of this study provides a summary of recent studies on consumer food handling and storage practices, as they are relevant to how consumers may interpret different product open dates.
