I don't know about into the product, just that if you wash them (preferable adding a little clorox to the water), they're much safer. I think most of the bactera/viruses, etc. are on the outside of the veggies. The general rule is to be especially careful with things like celery, onions, lettuce etc. because they grow close to the ground (where the fertilzer is) and it's harder to keep sand, grit and bad fertilizer out of the veggies. You've seen it on these things when you buy them at the supermarket--or you notice the grit on them if you have your own garden (presumably not using human waste as fertilizer).

From what I understand is the "fertilizer" is liquidfyed and sprayed over the produce thus fertilizing and watering at the same time.

Perhaps someone with direct knowledge can provide better info.

Seems to me that if the E Coli is in the ground around the veggies, the E Coli could get "percolated" up into the veggies through their water intake. Lettuce, cucumbers, celery etc. are a LOT of water.
