Just days after the Kroger Food Store announced it was voluntarily recalling all ground beef products that were sold between May 21 and June 8 at its stores following E. coli outbreaks in Michigan and Ohio, the U.S.’s largest grocery chain already faces its first lawsuit.

Amanda Adam from Ohio says she contracted E. coli from ground beef she purchased at a Kroger grocery store in Dublin, a Columbus suburb.

According to the lawsuit, she bought two beef patties on June 4 and cooked them the same day. Four days later, she began feeling ill and was admitted to a Cincinnati hospital on June 10. Tests at the hospital revealed she was infected with E. coli O157:H7, the same strain of the bacteria found in the Kroger ground beef outbreak.

E. coli is a potentially deadly bacterium that can cause diarrhea, stomach cramps, vomiting and in most severe cases kidney failure. Most of the infected persons get well in 15 days. People predisposed to the infection include children, seniors, and persons whose immune system is weakened.

There have been 18 cases of E. coli illnesses reported in Ohio and 16 cases in Michigan, local health departments announced.

The lawsuit accuses the grocer of negligence and seeks at least $25,000 in damages.

Kroger representative Meghan Glynn refused to comment on pending litigation.
