Chopped romaine lettuce grown in Yuma, Arizona is being blamed for an E. Coli outbreak that has reached 16 states so far, including Michigan.

The Centers for Disease Control reports that 53 cases of E. Coli have been reported, with Pensylvania, Montana, Idaho, and New Jersey reporting the highest number of cases. As of this writing, two cases have been reported in Michigan.

A single brand or supplier of chopped romaine lettuce has not been narrowed down, according to CNN.

"Most people reported eating a salad at a restaurant, and romaine lettuce was the only common ingredient identified among the salads eaten," the CDC said in a statement.

Symptoms of E. Coli include severe stomach cramps, diarrhea and vomiting. Patients usually show signs two to eight days after consuming foods contaminated with the bacteria.

The CDC is recommending that US consumers stay away from chopped romaine lettuce.
