It’s not yet clear how E. coli 0157 H7 contaminated spinach during the recent nationwide outbreak. One likely source of the E. coli bacterial strain is cattle waste, which could have tainted irrigation water used to grow the spinach.
Cattle can tolerate the bacteria with no problems, but E. coli can cause severe illness and even death in humans. At a University of Nebraska research feedlot near Lincoln, researchers are now working on an E. coli vaccine that would be given to cattle instead of humans.
