Notes from the Field: Salmonella Bredeney Infections Linked to a Brand of Peanut Butter — United States, 2012
In 2012, CDC collaborated with state health and agricultural agencies and the Food and Drug Administration (FDA) to investigate an outbreak of Salmonella Bredeney infections associated with exposure to peanut products manufactured by Sunland, Inc. of Portales, New Mexico (1).
On August 23, 2012, CDC PulseNet, a molecular subtyping network for foodborne disease surveillance, reported a cluster of 14 Salmonella Bredeney infections with an indistinguishable pulsed-field gel electrophoresis (PFGE) pattern. This PFGE pattern is rare, with five to eight reports uploaded to PulseNet annually (1). Salmonella Bredeney is a rare serotype, with only one documented outbreak in the United States before 2012.
During June 11–November 8, 2012, a total of 41 cases of Salmonella Bredeney infections were identified in 20 states. The median age of patients was 6 years (range: <1–79 years); 63% of patients were aged <10 years, and 60% were male. Among 36 patients for whom information was available, 10 (28%) were reported to have been hospitalized. No deaths have been reported.
Of the 32 patients for whom information was available, 25 (78%) had eaten a Trader Joe's brand Valencia peanut butter product manufactured by Sunland, Inc. Testing conducted by the New Jersey Department of Health, Virginia Division of Consolidated Laboratory Services, and Washington State Department of Agriculture laboratories isolated the outbreak strain of Salmonella Bredeney from three opened jars of Trader Joe's Creamy Salted Valencia Peanut Butter collected from three different patients' homes.
During September 17–October 16, 2012, FDA conducted an inspection of Sunland, Inc. manufacturing facilities (2). Environmental samples and samples from unopened peanut butter jars collected by FDA from the nut butter production facility yielded the outbreak strain of Salmonella Bredeney.
On September 24, 2012, Sunland, Inc. announced a voluntary recall of almond butter and peanut butter products manufactured in the Sunland, Inc. nut butter production facility during May 1–September 24, 2012. On October 4, 2012, Sunland, Inc. expanded its recall to include all products made in its nut butter production facility during March 1, 2010–September 24, 2012. On October 12, 2012, Sunland, Inc. extended the voluntary recall to include raw and roasted shelled and in-shell peanuts processed in its peanut processing plant (2). Approximately 300 products have been recalled (3).
CDC recommends that consumers not eat recalled Sunland, Inc. products or foods containing recalled products and discard or return any remaining recalled products.
