I purchased fresh bagged spinach within the time frame suggested by recent E.coli outbreak reports, and ate it with washed farmstand tomatoes with sald dressing. Within 24 hours, I became violently ill, required immodium, which was not very helpful. I was sick for about three days, and the laundry really built up. All the symptoms described in your description applied. I did not visit a doctor for lack of insurance. Also, at the time, I thought it might be some kind of food intolerance. This occurred in August/September. I have a receipt for the spinach, which was purchased at Aldi's, a discount grocery store.
If agribusinesses are using contaminated irrigation lines or are not properly providing for the hygiene needs of their field workers, it would appear that there is criminal negligence that they ought to compensate their customers for. Although I did not wind up in the hospital, I think I went through enough to deserve some kind of compensation.
