So it encourages consumers to throw away the romaine lettuce even if symptoms of E.coli infections did not occur. Restaurant also prevented to serve any salads containing romaine lettuce that came from Yuma, Arizona. Also the retailers not allowed selling any of it that came from the region.
What is E.coli?

Most E.coli strains are harmless and part of normal flora in the gut that offers benefits to the host. By producing vitamin K and preventing any pathogenic bacteria through symbiotic relationships. But some of its strain is harmful like E.coli 0157:H7 that cause serious illnesses. Like gastroenteritis, hemorrhagic colitis and urinary tract infections. The usual symptoms and sign of infections include diarrhea, abdominal cramps, vomiting and fever. Most likely children are more susceptible to infections that develop severe illnesses.
