WASHINGTON (Reuters) – Some 390 tons of ground beef produced by a California meat packer, some of it nearly two years ago, is being recalled for fear of potentially deadly E. coli bacterium tainting, U.S. officials said on Monday.

The beef was produced by Huntington Meat Packing Inc of Montebello, California, and shipped mainly to California outlets, the U.S. Department of Agriculture’s food safety arm said.

An initial problem, in ground beef shipped by the plant from January 5 to January 15, was discovered during a regular safety check, the Food Safety and Inspection Service said.

It said it had received no reports of illnesses associated with consumption of the recalled products.

During a follow-up review of the company’s records, government inspectors determined additional products produced and shipped in 2008 to be of concern because they may have been contaminated with E.coli, the service said in a notice on its web site.

This batch was produced from February 19, 2008, to May 15, 2008. It also had been shipped to distribution centers, restaurants and hotels within California, the notice said.

“While these products are normally used fresh, the establishment is taking this action out of concern that some product may still be frozen and in commerce,” it said.

E. coli is a potentially deadly bacterium that can cause kidney failure in the most serious cases.

The service said it routinely conducts checks to verify that recalling firms notify customers, including restaurants, of the recall and that steps are taken to make sure the product is no longer available to consumers.

The CDC said a New York adult with underlying medical conditions had died and another possibly related death in New Hampshire was under investigation. State officials attribute the New Hampshire death to the O157:H7 E. coli bacteria.

All but three of the 28 cases listed by the CDC were in the U.S. Northeast and 18 were in the New England states. Sixteen hospitalizations were reported, said a CDC spokeswoman. The bacteria involved were from a common strain, so tests were under way to see if all of the reported cases were related.

Over the weekend, Fairbank Farms of Ashville, New York, recalled 545,699 lbs (248,450 kg) of ground beef products.

The Agriculture Department, which oversees meat safety, said an investigation led it to conclude “there is an association between the fresh ground beef products and illnesses in Connecticut, Maine and Massachusetts.” USDA worked with state and federal officials in examining a cluster of E. coli O157:H7 illnesses.

A potentially deadly bacteria, E. coli can cause bloody diarrhea, dehydration and, in severe cases, kidney failure. The very young, the elderly and people with weak immune systems are the most susceptible to foodborne illness.

A string of food-borne safety scares led the U.S. House of Representatives to pass legislation this summer to require more inspections and oversight of food manufacturers and would give the government new authority to order recalls.

Fairbank Farms announced the recall on Saturday. The beef was produced in mid-September and probably was labeled for sale before the end of the month, said USDA.

It went to retailers including Trader Joe’s, Price Chopper, Lancaster and Wild Harvest, Shaw’s, a unit of Supervalu (SVU.N), BJ’s (BJ.N), Ford Brothers and Giant, a unit of Ahold (AHLN.AS), in eight states — Connecticut, Maryland, Massachusetts, New Jersey, New York, North Carolina, Pennsylvania and Virginia.

The beef was produced Sept. 14 to 16, and the company urged consumers to check their freezers for products listed in the recall. Labels of the recalled packages will say EST 492 inside the USDA
