Just got this in an email, and I'm saving the site! :)
How long can a bottle of ketchup stay in your fridge before it goes bad? I'm thinking quite awhile, but if you want an expert opinion, go to the web site below. This site lists all kind of foods and how to keep them fresh longer as well as when to get rid of them. If you have a question click on the particular picture, and a whole list of stuff appears.............WHAT A GREAT SITE!!!!!!!!!!!!!
