Canning greenbeans in a pressure canner?

Here's why:

* Botulism Risk: Green beans are a low-acid food. This means they can harbor the bacteria Clostridium botulinum, which produces a deadly toxin. Pressure canning is designed for high-acid foods, and it doesn't achieve the necessary temperatures to destroy botulism spores in low-acid foods like green beans.

* Proper Method: Green beans should be canned using a boiling water bath canner. This method reaches the proper temperature to safely kill bacteria.

Important Notes:

* Follow Tested Recipes: Always use a recipe from a reliable source, like the USDA's Complete Guide to Home Canning.

* Proper Processing Time: Processing time is crucial. Insufficient processing time can leave harmful bacteria alive.

* Quality Control: Always check for signs of spoilage, like bulging lids, leaks, or an off-odor.
