The voluntary recall issued recently by Diamond Pet Foods at the request of the United States Food and Drug Administration has been expanded to include another variety of dog food. This recall was issued due to a possible salmonella contamination. In addition to the pet food varieties named in the previous recall, Diamond Pet Foods has most recently announced a voluntary recall for its Diamond Naturals Small Breed Adult Dog Lamb & Rice Formula dry dog food, manufactured August 26, 2011. The product was distributed for sale at pet stores and other retail outlets throughout the states of South Dakota, Tennessee, Texas, Illinois, Kentucky, Louisiana, Michigan, Colorado, Minnesota, Missouri, Oklahoma, Pennsylvania, and Wisconsin. Products affected by this recall include 6 pound, 18 pound, and sample size packages of Diamond Naturals Small Breed Adult Dog Lamb & Rice Formula. All packages of affected dog food are imprinted with production code DSL0801 and best by dates ranging from August 26, 2012 to October 18, 2012. Dogs who have ingested food contaminated with salmonella may exhibit loss of appetite, high body temperature, and stomach pain. Untreated pets may become nauseous or have diarrhea. Humans, especially those with weakened or compromised immune systems such as children, the elderly, and those infected with HIV/AIDS, who handle the pet food without washing their hands thoroughly afterward may also become infected with salmonella, a condition that can lead to nausea, vomiting, diarrhea, abdominal cramping and fever.
