On May 3, 2012, the U.S. Centers for Disease Control and Prevention (CDC) connected the human Salmonella illnesses with recalled dog food produced by Diamond Pet Foods using the national subtyping network, PulseNet.

While no deaths have been reported, five people were hospitalized with the rare strain of Salmonella Infantis, according to the CDC. The nine states that reported the infections included Alabama, Connecticut, Michigan, Missouri, North Carolina, New Jersey, Ohio, Pennsylvania, and Virginia.

The Michigan Department of Agriculture and Rural Development first detected the Salmonella contamination of dog food during routine retail testing of the pet food in April 2, 2012. The testing revealed the rare strain of Salmonella in an unopened bag of Diamond Naturals Lamb Meal and Rice dry dog food, which had been collected March 14, 2012.

Public health investigators then interviewed ill people infected by the Salmonella Infantis strain.

"In interviews, ill persons answered questions about contact with animals and foods consumed during the week before becoming ill," the CDC reported. "Seven of 10 (70%) ill persons interviewed reported contact with a dog in the week before becoming ill. Of 5 ill persons who could recall the type of dog food with which they had contact, 4 (80%) identified dry dog food produced by Diamond Pet Foods that may have been produced at a single facility in South Carolina."
