A method of determining whether a product is within a useable shelf life includes obtaining a first set of data associated with the product, wherein the first set of data includes a first timestamp and a first assessed quality, obtaining a second set of data associated with the product, wherein the second set of data includes a second timestamp and environmental history data, computing a second assessed quality using the first and second timestamps and the environmental history data, and determining whether the product is within the useable shelf life using the second assessed quality.
