Do you need to sterilize mason jars when used right away?

Question

I made a small batch of raspberry jam and figured I wouldnt need to sterilize the jar since I only made one. Its never been sealed and is in my fridge. Is there any danger for botulism?

Answer 1

The National Center for Home Food Preservation at the University of Georgia says that it is "unnecessary to presterilize jars for fruits, tomatoes, and pickled or fermented foods that will be processed 10 minutes or longer in a boiling-water canner."

Berries tend to be more acidic, so botulism would not be as likely however, bacteria, yeast, and fungi can grow if jars are not pre-sterilized or processed long enough as mentioned in this article. I hope this helps!
