Do you need to refrigerate ketchup?

Yes, it’s true. The reason for this is because it contains vinegar and other acidic ingredients, which can cause food to break down, grow mold, or become unsafe to eat.

Does ketchup need to be refrigerated after opening?

When it comes to the question, “does ketchup need to be refrigerated after opening?” the answer is generally “no.” While opened ketchup may not be safe to consume after just a few days, it’s perfectly fine to enjoy an opened jar of Heinz or any other brand of ketchup as long as it’s still in its original packaging.

Does ketchup need to be refrigerated after opening for storage?

Most experts say no. Although the jar may look cloudy after opening, the ingredients in the sauce do not degrade after opening and do not need to be refrigerated.

Can ketchup go bad once opened?

The short answer is no. Even though some brands do contain vinegar, which can be an indicator of spoilage, the acidic ingredients that help create a nice, thick consistency don't go bad. Plus, the ingredients are pasteurized to kill bacteria, so once opened, the sauce should continue to last for a month at room temperature, or three to four weeks in the refrigerator.

It's always a good idea to store opened bottles in the refrigerator anyway, just to be safe. The short answer is no, it’s perfectly fine to keep opened bottles of ketchup in the refrigerator. In fact, doing so makes perfect sense.
