The shelf life of any product depends on factors including the ingredients, packaging and storage conditions. We monitor our products in the stores to ensure that they continue to meet our high standards for quality and freshness. The ""Best When Used By"" date printed on each package represents the last day the product should be consumed to guarantee the best quality, freshness and flavor of the product. A sample "Best When Used By" code date would be: 01 May 2007 01 = Day of Month May = Month 2007 = Year of Expiration
