I processed green beans in a boiling water bath about a week ago. My neighbor told me I should have used a pressure canner. Would it be alright to reprocess the beans now in a pressure canner?
Since more than 24 hours have passed since the beans were processed in a boiling water bath, there is a good chance that they have already started to spoil. Throw them out. They could be dangerous. Clostridium botulinum could produce toxin within this amount of time without any noticeable changes in the food.
Note: All low acid foods must be processed in a
steam pressure canner.
