The Centers for Disease Control and Prevention (CDC) now reports that a total of 22 people have been infected with the outbreak strain of Salmonella Infantis that has been linked to contaminated dog food produced by manufacturer Diamond Pet Foods.

Twenty people have been reported ill from 13 states, and two people have been reported ill from Canada, the CDC announced June 13, 2012. Of the people reported ill, the CDC says six have been hospitalized. No deaths have been reported.

Illnesses began between October 2011 and May 11, 2012. Affected people have ranged in age from under a year old to 82 years old, and 68 percent of the patients have been female.

The CDC notes that illnesses that occurred after May 11, 2012 may not yet be reported due to the time it takes between when a person becomes ill and when the illness is reported.
