Freezing doesn't kill C botulinum, but it doesn't let whatever microorganisms that are present grow. To produce the toxin they have to be respiring, which they can't do in a frozen state. Even if the beans are thawed and refrozen the conditions necessary for botulinum poisoning aren't present. Eat 'em up. Yum!

Thanks Bill for the explanation. I feel better...one of our favorites...and easy when using a frozen 1 lb. bag of green beans...a little diced red pepper; a small onion; garlic salt and sauteed in real butter. Yummy!
