At least 33 people are sick, including 11 hospitalized, from salmonella-tainted ground beef linked to nearly 30,000 pounds of recalled hamburger on Sunday.

People in seven states have been infected with salmonella Enteritidis linked to beef produced by Cargill Meat Solutions of Wyalusing, Pa., officials with the Centers for Disease Control and Prevention said Monday.

The 85-percent lean ground beef was produced on May 25. 

Ill people include 14 in New York, 10 in Vermont, three in Massachusetts, two in Virginia and New Hampshire and one in Maine, the CDC said.

Illnesses began in early June. Those that occurred after June 29 might not yet be reported because of the lag in time between when illness occurs and when it’s documented.

Cargill officials recalled 29,339 pounds of meat, packaged in 14-pound chubs, after the outbreak was detected. Federal officials with the U.S. Department of Agriculture’s Food Safety and Inspection Service linked the beef to five infected patients.

Consumers should check their freezers for recalled products and discard them. The recalled meat bears the establishment number “EST.9400” inside the USDA mark of inspection.
