My mom forwarded me a great site that I had never visited before called Still Tasty. You can check the shelf/fridge/freezer life of all sorts of food. So that ground beef that's been in your freezer for 2 months? You have 4 months left before you should get rid of it. What about that feijoa on your counter? 2-3 days or until ripe, a little longer in the fridge.
The site has listings for everything from spelt, to bison, to deer, to alcoholic beverages. Even goat and chocolate chips. Check it out if you have questionable items in your kitchen. I know we all do. I don't think I need any help with that plain yogurt that's been in the back of my fridge for a while though. Yuck.
Feijoa, by the way, is also known as pineapple guava. Who knew?
