Karen and James Evans claim they got sick and so did their children from eating hamburgers at a Fitchburg Tony Roma's in December. Karen Evans had to be hospitalized for nearly 10 days.

They allege Rochester Meat Co. of Rochester, Minn., produced the burgers and was negligent for allowing E. coli to infect their meat.

The company in January issued a recall of nearly 200,000 pounds of beef over concerns it may have been contaminated with E. coli.

The lawsuit seeks unspecified damages. Company officials didn't immediately return a message Thursday.
