How long does salad dressing last in the Frig after opening??!
Answers: along with ketchup and BBQ sauce and things of the sort?
They generally will last for many, many months, just go by the date stamped on the side, although I have used dressings after the date and they were still fine. I usually have yellow mustard for at least a year since we don't eat it often and it has never gone bad. So my advice, unless it smells funny or the date is way past, it's probably fine.
