In 2013 the New Hampshire Department of Health and Human Services investigated a cluster of Salmonella Typhimurium infections associated with contaminated locally made pet treats. Between June and October 2013, a total of 43 ill persons were identified. Sixteen patients were hospitalized. Among 43 case-patients interviewed, the proportion exposed to dogs (95%) and pet treats (69%) in the 7 days prior to illness was statistically higher than among participants in a US population based telephone survey. On further interview, 38 (88%) reported exposure to Kritter's Kitchen Kreations pet treats. Product testing isolated the outbreak strain from four of four Kritter's Kitchen Kreations Chicken Jerky samples. A site visit at the production facility revealed inadequate processing of the chicken jerky, bare-hand contact with the finished product prior to packaging and use of vacuum-sealed packaging which may have facilitated anaerobic bacteria to proliferate.
