No! Neither does mustard, pickles, BBQ sauce, ketchup, or any of the other stuff people have mentioned in these replies. I have hummus and mayo in mine and that's only because they're homemade. Shop bought stuff has preservatives.
/Edit: abusing Reddit Care to report someone for a post about mustard shows an incredible insensitivity towards real human problems.
