Children are too small to tolerate much blood and fluid loss.
It is for this reason that small children should not be allowed to become dehydrated, even in mild cases of diarrhea. The presence of this bacterium can also be very dangerous to pregnant women, the elderly or infirm. Recently, outbreaks of E.Coli bacteria have been linked to fresh produce such as lettuce, alfalfa sprouts and unpasteurized apple cider and juices. Freshly squeezed orange juice even from Brand labels cannot be considered safe unless it is pasteurized. Ground beef is more likely to harbor E. Coli than whole cuts.
