Dried tomatoes in olive oil
Thanks for contacting Ask the Expert. Oven dried tomatoes that are preserved in olive oil must be stored in the refrigerator for no more than 4 days, or frozen. Storing them at room temperature in the pantry creates an environment favorable to the development of botulism spores.
So I need to throw away the jar I did store in the pantry for a week now?
Yes. There is no way to tell if the product is still safe to eat.
