Owners should make sure they store their pet food in an area away from the kitchen and in a cool, dry place, it has been claimed.
Tara Parker-Pope, writing for the health blog of the New York Times, revealed that salmonella can lurk in pet food, so owners should be cautious when it comes to handling their four-legged friends grub.
Dr Casey Barton Behravesh, a veterinary epidemiologist at the Centers for Disease Control and Prevention, told the news provider: "The problem of salmonella in pet foods and pet treats, even in pet supplements like vitamins, is something people should be aware of.
"It's important for people to know that after they feed their pets or give them treats, they should wash their hands."
To lower risk of salmonella exposure to humans and pets, owners should keep food away from the kitchen and wash food and water bowls regularly, Ms Parker-Pope wrote.
Symptoms of salmonella in pets are similar to those experienced by people: lethargy, fever, vomiting and bloody diarrhoea.
