Update: recall of dry dog and cat food products associated with human Salmonella Schwarzengrund infections--United States, 2008

MMWR Morb Mortal Wkly Rep. 2008 Nov 7;57(44):1200-2.


On May 16, 2008, CDC reported on a 2006-2007 multistate outbreak of infection with Salmonella enterica serotype Schwarzengrund that was associated with dry dog food. At the time of that report, a total of 70 cases had been reported from 19 states, with the last case identified on October 1, 2007. Subsequently, an additional case was identified on December 29, 2007. Epidemiologic and environmental investigations have suggested the source of the outbreak was dry pet food produced by one manufacturer, Mars Petcare US. This report updates the previous CDC report, provides additional epidemiologic findings, and describes additional actions taken by public health agencies and the manufacturer. In 2008, eight more cases have been reported, bringing the total number of cases in the outbreak to 79. On September 12, 2008, the company announced a nationwide voluntary recall of all dry dog and cat food products produced during a 5-month period at one Pennsylvania plant. Dry pet food has a 1-year shelf life. Contaminated products identified in recalls might still be in the homes of purchasers and could cause illness. Persons who have these products should not use them to feed their pets but should discard them or return them to the store.
