A woman from Ligonier, Pennsylvania became the first in Westmoreland County to sue the Sheetz convenience store chain over an outbreak of salmonella bacteria this summer.

Amanda G. Moore says she got sick after eating a chicken salad sandwich she bought at the chain’s Irwin store on Route 30. Moore says she was hospitalized and sick for about a week.

Sheetz officials say they’ve been working with those who have already sued the Altoona-based chain, and have settled some lawsuits already. They didn’t specify how many suits have been filed or settled.

More than 400 people in nine states, including nearly 300 in Pennsylvania, who ate Roma tomatoes on sandwiches at the stores got sick. Coronet Foods of West Virginia, which cut and packaged the tomatoes, shut down in October due to concerns over the outbreak.

Moore sued Sheetz, Coronet and two produce wholesalers who allegedly sold the tomatoes.
