Most strains are harmless, but some can cause serious food poisoning. The E-coli bacterium grows massively in fresh fecal matter. Virulent strains can cause gastroenteritis, urinary tract infections, hemorrhagic colitis, and Crohn’s disease. Common signs and symptoms include severe abdominal cramps, diarrhea, hemorrhagic colitis, vomiting and sometimes fever. In rare cases, virulent strains are also responsible for bowel necrosis or tissue death and perforation. The incubation period is usually 3–4 days after the exposure, but may be as short as one day or as long as 10 days.
