"As of now, there is no indication that the major national name-brand jars of peanut butter sold in retails stores are linked to the recall," Sundlof told reporters in a conference call.
Officials are focusing on peanut paste, as well as peanut butter, produced at a Blakely, Ga., facility owned by Peanut Corp. of America. Its peanut butter is not sold directly to consumers but distributed to institutions and food companies. But the peanut paste, made from roasted peanuts, is an ingredient in cookies, cakes and other products that people buy in the supermarket.
"This is an excellent illustration of an ingredient-driven outbreak," said Dr. Robert Tauxe, who oversees foodborne illness investigations for the Centers for Disease Control and Prevention.
So far, more than 470 people have gotten sick in 43 states, and at least 90 had to be hospitalized. At least six deaths are being blamed on the outbreak. Salmonella is a bacteria and the most common source of food poisoning in the U.S., causing diarrhea, cramping and fever.
Officials said new illnesses are still being reported in the outbreak investigation.
