E. coli is
a bacteria common in the digestive tract of mammals, and is in high
concentration in feces of dogs and cats. Inside a human or a dog, this
bacteria, as part of the normal flora, causes no harm. However, certain
strains of E. coli can produce potent toxins, which can be dangerous,
even lethal. This occurs most commonly when food is contaminated by E.
coli, and allowed to spoil at room temperature. Cleanliness,
refrigeration and thorough cooking help protect us from the toxins. A
child has minimal risk of E. coli problems directly from a dog. Fecal
contamination of food, such as unwashed vegetables or a hot dog dropped
in the yard, and eaten later by an unattended child is of much more
concern
