How long do breadcrumbs last? I'm currently trying to make a dish that calls for breadcrumbs, but the only ones I have expired on October 22 of 2019.  They are unopened and were kept in a cool dry place. It sounds stupid but are these still usable?
If they're the dried bought type, they keep almost indefinitely so long as they stay dry (even open; I use them very slowly) . The date is about quality not safety. 

As always, if there seems to be anything wrong, such as signs of dampness on the container (at least here they're packed in cardboard), be more cautious
