I just bought a jar of Wegman's Horseradish Mustard today. It is in a plastic jar with a peel and lift seal under the lid. When I opened it, the seal itself appeared to be intact and didn't look like it had been opened, but there was dried mustard on the neck of the jar just under the top where the seal is. So I'm wondering if that's a sign the seal was punctured or leaked. What do you think, safe to eat or best not to take chances?
