A Brookline woman hospitalized for four days after eating what authorities say is contaminated beef is suing the slaughterhouse and the butcher shop believed to have supplied the meat.

Anne Boldys filed her suit in Essex Superior Court on Tuesday against Adams Farm Slaughterhouse of Athol and Eva’s Farm Organic Butcher Shop of Middleton.

According to the suit, Boldys is among several people who developed E. coli after eating beef from Adams Farm.

Seven people — including three from Massachusetts — became ill with E. coli between June 27 and Sept. 4, according to the US Centers for Disease Control and Prevention. Five needed to be hospitalized, but none developed hemolytic uremic syndrome, a type of kidney failure that is the most dangerous result of E. coli infections, the CDC reported. No deaths have been reported.

The slaughterhouse on Saturday recalled beef, veal, and bison that had been slaughtered in July and August and shipped to farmers’ markets, retail stores, and restaurants in Massachusetts, Connecticut, and Eastern New York.

According to the suit, Boldys’s parents bought ground beef from Eva’s on or about Aug. 27 and Boldys ate it that day or the next. She became ill with nausea, vomiting, and diarrhea around Sept. 2. She was hospitalized at North Shore Medical Center in Salem from Sept. 4 through 8, and “continues to slowly recover,’’ the suit said.

Boldys is 25 years old and works in administration at Boston Children’s Hospital, according to one of her lawyers, Bill Marler.

Reached by phone Tuesday, the butcher shop owner, Roberto Alonzo, said he was not aware of the suit and declined to comment.

Ed Maltby, general manager of the slaughterhouse, did not reply to messages left Tuesday and Wednesday. But on Saturday, he told the Globe he learned of the contamination on Friday and has been working with the US Department of Agriculture to identify its cause. “We want to do anything possible to prevent any spreading of illness,’’ he said.
