FRIDAY, Jan. 16 (HealthDay News) -- Cereal giant Kellogg recalled 16 products containing peanut butter late Friday, as U.S. health officials expanded their investigation into peanut products possibly contaminated with salmonella.
As the toll from the outbreak climbed to 453 people sickened in 43 states and Canada, with six deaths, the possibility that contaminated products were on store shelves became an apparent reality.
Kellogg's recall included Keebler cheese and peanut butter sandwich crackers and Keebler and Famous Amos peanut butter cookies.
The company had asked stores on Wednesday to stop selling its popular Keebler and Austin brand peanut butter crackers while it investigated any possible salmonella connection.
Friday's formal recall took the company's action one step further.
"The actions we are taking today are in keeping with our more than 100-year commitment to providing consumers with safe, high-quality products," David Mackay, Kellogg president and CEO told the Associated Press. "We apologize for this unfortunate situation."
Kellogg's recall also followed a request from the U.S. Food and Drug Administration for salmonella testing by food companies around the country that may have bought peanut butter or peanut paste from a Georgia facility owned by the Peanut Corp. of America.
U.S. health officials late Friday said at least 85 companies had purchased peanut products from the Georgia plant and 30 had been "urged" to run their own tests for the bacteria, the AP reported.
Dr. Stephen Sundlof, director of the FDA's Center for Food Safety and Applied Nutrition, told a late Friday teleconference: "We have traced one likely source of salmonella contamination to a plant owned by the Peanut Corp. of America in Georgia, which makes both a brand of peanut butter distributed in bulk to large institutions like nursing homes, and also produces a peanut paste that is distributed to food manufacturers to be used as an ingredient in many products, including cookies, crackers, cereal and ice cream."
Although salmonella was found at the plant, it's not yet known whether it's the same strain behind the outbreak, Sundlof said, adding that testing continues.
Sundlof said the FDA doesn't know all the peanut butter brands or foods containing peanut butter that might be affected. "We don't have specific information about what brands or products consumers should avoid," he said.
He added, however, that popular brands of peanut butter found on store shelves don't seem to be affected.
But AP, quoting consumer representatives who took part in an earlier-Friday conference call with federal officials, said companies producing products with peanut butter were being asked to consider halting sales.
The concern is that peanut paste is used in dozens of products, from baked goods to cooking sauces. Initially, federal and state investigators had focused on bulk containers of peanut butter sold to institutions such as nursing homes, but not to supermarkets, the AP said.
"Now it turns out, it's not just institutions," said Michael Hansen, a senior scientist with Consumers Union.
On Wednesday, Kellogg, of Battle Creek, Mich., said it hadn't received any complaints or discovered any problems with its crackers, but took the stop-sale action as a "precautionary measure" after Peanut Corp., one of its suppliers, announced a nationwide recall of peanut butter made at the Georgia plant.
