Two dogs have now been confirmed to have Salmonella infections linked to recent Diamond Pet Foods recalls, according to US Food and Drug Administration's Center for Veterinary Medicine deputy director of communications staff, Laura Alvey.

Both dogs lived in the same house as a Salmonella infantis outbreak victim and were fed one of the recalled dry dog food products, produced at Diamond Pet Foods' Gaston, South Carolina, USA, facility. So far, a total of 16 human cases of Salmonella have been linked to the recalled dog food products in Alabama, Connecticut, Michigan, Missouri, North Carolina, New Jersey, Ohio, Pennsylvania and Virginia, USA, and Quebec, Canada.

Diamond Pet Foods shut down its Gaston facility "to clean and implement additional procedures" after a link was confirmed between the illnesses and dry dog food samples manufactured at the plant, according to Alvey.
