The first documented outbreak of human salmonellosis traced to dry pet food may have been largely transmitted by cross-contamination after feeding a pet in the kitchen, according to CDC investigators. The salmonellosis outbreak involved 79 cases across 21 states -- most of them in the Eastern U.S. -- over a three-year period, with around half of the cases (48%) occurring among children under age 2, according to Casey Barton Behravesh, DVM, DrPH, of the CDC, and coauthors.
