All of the recipes I can find for canning green beans require a pressure canner. Is there a safe way to can green beans using a boiler canner?

First and foremost, canning low acid foods like beans MUST be done in a pressure canner. A safe pressure canning process is required to destroy the organisms and spores that cause botulism. Old recipes exist on the internet where people were instructed to boil vegetables for many hours, but that still does NOT kill botulism spores.
Next, to ensure safety, Extension only recommends research-based, safe, canning processes. These can be found on the USU Extension website and http://www.homefoodpreservatio
There are a few recipes for pickling beans. When pickling, acid is added to a level that prevents growth of the botulism organism. With enough acid present, a boiling water canner can be used. Here's a recipe for pickled dilled beans:

- I grew up eating green beans which were pressure-canned at home. When my mother heated them for a meal, she brought them to a boil then removed the lid and let them boil for at least a minute with the lid off. She said this was necessary to be safe. Is it necessary or was that just something passed down from before pressure canning was available?

I have heard somewhere that tomatoes are an exception, and there could be a problem with the tomatoes that would not be able to be detected, and that they should just be discarded at the expiration date for safety's sake. Is this true?
