Dry dog food, similar to that pictured here, was recalled after samples tested positive for Salmonella. Diamond Pet Foods expanded its recall to include several well-known brands, among them Natural Balance.
Diamond Pet Foods has expanded its voluntary recall of possibly contaminated dry pet food after sampling revealed Salmonella in some of Diamond's products.
These include batches of nine brands manufactured between Dec. 9, 2011, and April 7, 2012.
The Federal Food and Drug Administration said Monday that no dog illnesses have been reported, but Salmonella can affect both the dogs eating the product and humans who come into contact with it.
The Centers for Disease Control has reported 14 cases of humans infected with Salmonella Infantis in nine states, all attributed to handling dry dog food.
Individuals handling dry pet food can become infected with Salmonella, especially if they have not thoroughly washed their hands after having contact with surfaces exposed to the product.
While the Diamond products have not been directly distributed in California, the FDA warns they may be found beyond the nine states originally listed in the recall, and some products may have been sold online.
They include a number of well-known premium brands, the kind people might purchase online without knowing where they originated.
Brands involved in the recall include:
Natural Balance is recalling some of its dry dog food flavors because they were manufactured by Diamond Pet Foods.
On its website, Natural Balance said every lot of its food is tested for nine known contaminants including Salmonella, but it issued the voluntary recall as a precaution.
In 2010, sampling of Natural Balance's Sweet Potato & Chicken dry dog food tested positive for Salmonella and was recalled.
WellPet LLC has recalled Wellness Complete Health Super5Mix Large Breed Puppy, 15- and 30-pound bags and 5 oz sample bags.
Costco’s Kirkland Signature products are also included in the recall list.
