Does ketchup have an expiry date?!
Answers: I have a bottle of ketchup in my fridge from about a year ago, opened. It has the date 20Sept2007 on it: Is that the expiry?
Yes it doe's. If you notice any black coloration around the lid on the inside be careful, this is what they call botulism and can make you very sick and even may expire from it. Always wash the lid and refrigerate after each use. Anyone who tells you no to your question is full of it and needs to wipe the BS from their mouth. I'm glad you asked this question. Hopefully other's will learn from it as well.
yes. and its catsup not ketchup. remember, all foods have expiry date
yes it is,
anything over 3 month should be tossed if not used by then.
no
That is the use by date for the best quality. Ketchup will darken and taste sour as it gets older, but because of the acidity has a long shelf life before this happens.
