Notes From the Field: Infections With Salmonella I 4,[5],12:i- Linked to Exposure to Feeder Rodents-United States, August 2011-February 2012

摘要

CDC IS COLLABORATING WITH 22 STATE health departments in an ongoing investigation of an outbreak of human Salmonella I 4,[5],12±- infections associated with exposure to rodents sold as food for pet reptiles and amphibians (i.e., feeder rodents). This outbreak strain also was implicated in a 2009 outbreak in the United Kingdom and a 2010 outbreak in the United States, both linked to frozen feeder rodents from a single U.S. supplier, resulting in recalls. During August 29,2011-February 2, 2012, a total of 46 cases of human Salmonella 14, [5] ,12:i:- infection were reported in 22 states. The median patient age was 11 years (range: <1-69 years); 37 percent were aged <=5 years, and 52 percent were male. Of the 27 patients interviewed, six (22 percent) reported hospi-talization, 20 (74 percent) reported reptile or amphibian exposures, and 15 (56 percent) reported feeder rodent exposure. For 12 patients who recalled the types of rodent contacted, five (42 percent) reported exposure to live rodents, four (33 percent) to frozen rodents, and three (25 percent) to both live and frozen rodents. Seven (58 percent) patients reported exposure to mice, two (17 percent) to rats, two (17 percent) to both mice and rats, and one (8 percent) was unsure. No patients reported exposure to rodents purchased from the same pet store.
