Initially a bit skeptical, I went through a number of items and found that it was decent. While it is always difficult to capture all situations, the ball park numbers provided can be useful for those who provide information to consumers. Of course, there are limitations. There are a number of different package types that will impact how long product can be held. Additionally, the ingredients, including preservatives, and how the product was processed will come into play. But for ball park estimates on shelf-life, it is worth the download. And coming from USDA, it can be considered validation support. (But nothing matches the support of a good Extension professional).
Shelf Life Advise is another good on-line resource for shelf life information.
