This case involves a child from Nevada who contracted e coli after eating lettuce that was served to her at a day camp. The child developed severe complications from the e coli infection, including hemolytic uremic syndrome and kidney failure. It was alleged that the lettuce in question was purchased at a grocery store. The e coli sample was sent to the state department of health for DNA testing. Counsel sought an expert in food-born contaminants to determine where the e coli sample originated from.
