Chopped romaine from Yuma, Arizona, has caused a large multistate breakout of E.coli, according to the CDC.
So far, there have been 35 confirmed cases of the illness across 11 different states. 22 of the cases resulted in the patients being hospitalized.
Symptoms of E. coli typically begin two to eight days after consuming the bacteria, although most patients become ill three or four days after consumption. Symptoms include severe stomach cramps, diarrhea and vomiting.
Most people recover in five to seven days. The people most at risk for E. coli illness include the very young, the very old and individuals with compromised immune systems.
