Used canning jars and botulism
I just started canning last year and this year found some used canning jars at a yard sale for a great price.
When I told a neighbor about this she said I shouldn't use the jars as they may have had something in them in the past that had botulism in them -- and now I am worried.
I would think that now that they are empty and exposed to oxygen, if I wash them and sanitize in dishwasher they should be safe -- won't they?
I know I'm being paranoid but to much out on the web theses days about botulism caution.
