Oh, wow, I will google and see what I can find to look into. Thanks for the info.
Yes, on splashing leafy greens with contaminated soil. I am thinking that washing your vegetables is a good idea to make you feel better, but the truth is many of those kind of bacteria can live in pretty harsh conditions and merely washing produce in some water and patting it dry will not kill anything serious. Bleach or boiling/freezing temps are the only things that will kill some bacterias... I would think putting down a layer of adequate mulch would significantly reduce soil splashing onto leafy greens though.
