BOSTON -- A Rhode Island mother says an ordinary hamburger turned her family upside down.

NewsCenter 5's Pam Cross reported Wednesday that her sixth-grade son contracted E. coli, and after two weeks of medical worries, they are suing a Massachusetts company.

Austin Richmond, 11, has been quarantined for two weeks after being stricken with E. coli.

In mid-October, he returned from a four-day trip sponsored by his middle school. The next day he got sick.

"I went to work. Jason was here, and by the time I came home he had fever and body aches and headaches, so I took him in to Hasbro Children's Hospital," Jaimee Richmond said.

It took 10 days of trips to the hospital before doctors diagnosed that he had one of the worst strains of E. coli -- one that can lead to kidney failure.

"I've never seen anything like it. It was just so scary," Richmond said. "I was so stressed. He was missing school, two teams of soccer, Boy Scouts, church, CCD -- everything that he normally does."

Questions from the CDC led to tainted beef and hamburgers eaten during the school trip. It was reportedly supplied by South Shore Meats, of Brockton. His family has filed a lawsuit. A company spokesman was not available.

Another meat processor, Fairbank Farms, of N.Y., recalled 500,000 pounds of beef. The recalls aren't connected.

Austin's not the only one to get sick. Thirty students and adults at his middle school have confirmed cases of E. coli.
