I think you can add some lime to the soil and let it sit for a few months. Supposedly that will take care of any disease. Perhaps someone else can chime in on this?
Hopefully, it was "potting mix" and not "soil". Since you are growing in containers, it needs to be light, fluffy and well-draining. You can make your own if you need to from peat moss or coco fibre, perlite and vermiculite. There's lots of info right here on Tomatoville.
