From the FDA: United Pet Group Expanded Recall

This recall includes a long list of pet nutritional products, all of which have been recalled for possible salmonella contamination.

For a complete list of the recalled products, see the FDA announcement.

From the FDA:
Pets with Salmonella infections may be lethargic and have diarrhea or bloody diarrhea, fever, and vomiting. Some pets will have only decreased appetite, fever and abdominal pain. Infected but otherwise healthy pets can be carriers and infect other animals or humans. If your pet has consumed the recalled product and has these symptoms, please contact your veterinarian.

People who handle these products can become infected with Salmonella, especially if they have not thoroughly washed their hands after having contact with them or any surfaces exposed to these products. Healthy people infected with Salmonella should monitor themselves for some or all of the following symptoms: nausea, vomiting, diarrhea or bloody diarrhea, abdominal cramping and fever. Rarely, Salmonella can result in more serious ailments, including arterial infections, endocarditis, arthritis, muscle pain, eye irritation, and urinary tract symptoms. Consumers exhibiting these signs after having contact with the product should contact their healthcare providers.
