Laboratory Samples Update
May 30, 2012
Samples of Diamond Puppy Formula dry dog food collected by FDA during an inspection at the Gaston, SC production facility yielded Salmonella Infantis, which led to a recall of the product on April 30, 2012. The inspection occurred as a result of the initial positive sample taken by the State of Michigan from an intact package of Diamond Naturals Lamb and Rice formula for Adult Dogs. That product was recalled on April 6, 2012.
During the inspection, FDA also collected environmental and ingredient samples at the facility, which so far have yielded negative results for the outbreak strain.
A surveillance sample of Diamond Naturals Small Breed Adult Lamb and Rice collected by the state of Ohio from the Diamond Meta, MO plant has now yielded a positive for Salmonella Liverpool (not the outbreak strain). Diamond has issued a recall for this product.
Additional investigational steps include analyzing consumer complaints to determine if they are related to this outbreak and continued state surveillance to determine whether any recall expansion may be required. The company is working with FDA to ensure adulterated products are not on the market.
