There's a recall involving boxes of frozen hamburgers.

Officials say a New Jersey-based meat company is voluntarily recalling some of its hamburgers after a cluster of illnesses in the Northeast caused by E. coli bacteria.

The New York Health Department says at least six people have fallen ill there. All are recovering. Contaminated burgers were found in one victim's home freezer.

The USDA says the recall affects more than 331,000 pounds of frozen beef patties that were distributed not just in New York, but nationwide.

They carried the number "Est. 9748" inside the USDA mark of inspection, and were produced June 22nd, July 12th or July 23rd.

The recalled products include certain 10-pound boxes of Butcher's Best 100-percent All Beef Patties; certain 10-pound boxes of Kohler Foods burgers; certain 10-pound boxes of Sand Castle Fine Meat; some two-pound boxes of Topps 100-percent Pure Ground Beef Hamburgers; and some three-pound boxes of Topps 100-percent Pure Ground Beef Hamburgers.
