I was wondering if there are any open sources/databases for which I can find standard food lifespans/expirations? This would possibly include shelf life estimations for raw/uncooked, refrigerated, cooked, or frozen food.

I've tried looking through the USDA and Open Food Facts but couldn't find any expiration-related data.

If anyone has any suggestions of where I can find this information (or if they know of a collection of sites that offer this info that I can scrape from) I'd love to hear it. If I end up needing to scrape the data from somewhere I'd be happy to release it back to the community.

I found a link to the Food Bank of Alabama, which has a 26 page PDF with a table of food expiration dates (pdf link). Here is another similar PDF, but even less machine readable. And here is yet another one (PDF).

It's not too machine readable, but you may be able to copy individual pages and paste them into a spreadsheet tool.

If this data source is useful for you, I can also help get it to be machine readable using a tool like pdftotext.
