Does ketchup have to be refrigerated after it's open?

The answer is no, but it's a good idea to be safe and put it in the refrigerator anyway. Condensation can form on the top of the ketchup as it's opened, which can cause bacteria to grow. Refrigerating it will prevent bacteria growth and extend the shelf life of the ketchup.
