The Centers for Disease Control is investigating a nationwide outbreak of infections caused by salmonella poisoing. While they have not confirmed the source of the contanimation in all states, health officials believe King Nut creamy peanut butter is a likely source of salmonella infections among many ill persons in Minnesota.

King Nut peanut butter is not sold directly to consumers and is not known to be distributed for retail sale in grocery stores but is distributed in some long-term care facilities, hosptials, schools, universities, restaurants, delis, cafeterias, and bakeries.

CDC is collaborating with public health officials in many states and the United States Food and Drug Administration (FDA) to investigate the outbreak.

As of Monday, Jan. 12, 410 persons infected with the outbreak strains of Salmonella Typhimurium have been reported from 43 states, including 8 cases in Missouri. Among the 388 persons with dates available, illnesses began between Sept. 3 and Dec. 31, 2008, with most illnesses beginning after Oct. 1, 2008.

To date, common brands of peanut butter sold in grocery stores do not appear to be associated with the outbreak. But on January 10, 2009, King Nut Companies issued a voluntary recall of peanut butter distributed under the King Nut label. In addition, King Nut Companies also issued a voluntary recall of Parnell’s Pride peanut butter distributed by King Nut, which is produced by the same manufacturer. The recalled products have lot codes beginning with “8”. No other King Nut products are included in this voluntary recall.
