At least one person in Pennsylvania might have been infected by an outbreak of a rare strain of salmonella poisoning linked to dog food, the state Department of Health has said.
At least 14 people in nine states have experienced salmonella poisoning from touching dry dog food, according to a report from the Centers for Disease Control and Prevention.
The case in Pennsylvania occurred last year, and the person had the same subtype of salmonella found in the dog food, but it is unclear whether there's a connection between the recalled dog food and that illness, the Department of Health said.
Certain brands of dog food were voluntarily recalled last month by Diamond Pet Foods, all manufactured at its South Carolina plant, the CDC said on Thursday. The recalled brands were: Chicken Soup for the Pet Lover's Soul, Country Value, Diamond, Diamond Naturals, Premium Edge, Professional, 4Health, Apex, Kirkland Signature/Kirkland Signature Nature's Domain, Canidae and Taste of the Wild.
Investigations are continuing to see if other brands of dog food made at the facility might be linked to human illnesses, the CDC added.
Besides Pennsylvania, the CDC reported cases in Alabama, Connecticut, Michigan, Missouri, North Carolina, New Jersey, Ohio and Virginia.
The 14 infections were reported from Oct. 8, 2011, through April 22, and five people were hospitalized, the CDC said.
The CDC statement identified the bacteria as salmonella infantis, which is considered a rare strain.
Pet owners should check their homes for recalled dog food products and get rid of them immediately, the CDC advises. People who think they might have become ill after contact with dry pet food or an animal that has eaten the dry pet food should talk to their doctor.
