Salmonellosis, the disease caused by an infection with the bacteria known as Salmonella, can have many different sources. In people, there are typhoid types of salmonellosis (caused by Salmonella typhi and Salmonella paratyphi) that are strictly human in origin. However, there are other forms, known as non-typhoid, that may result from ingestion of foods contaminated by infected animal feces.

Common examples of the non-typhoid form of salmonellosis are those derived from eating contaminated, uncooked eggs or undercooked meats or through more direct contact with the feces of animals infected with Salmonella.

Salmonella in Dog and Cats

Salmonella organisms are ubiquitous and can be isolated from animals that show no symptoms of illness. The organism is shed in the feces, potentially for a long period of time after infection.

  • Pig ear dog treats have been implicated as a potential source of Salmonella infection for dogs. They can also serve as a source of infection for people who handle them.
  • In addition, dogs and cats fed raw foods are more prone to shedding Salmonella organisms.
  • Many recalls involving commercial pet food diets and/or treats involve Salmonella contamination of the products. These contaminated products, if fed to your pet, could also cause salmonellosis for your pet and create an increased risk of shedding the organism.
  • Salmonellosis can be passed from pets to people as well as from people to pets.
  • Because of pets may lick themselves or eat feces, their saliva may contain Salmonella.

Salmonellosis in dogs and cats is often asymptomatic (showing no signs of disease.) However, when disease does occur, symptoms seen can include:

  • fever
  • lack of appetite
  • lethargy
  • diarrhea
  • abdominal pain
  • septicemia/endotoxemia (infection within the bloodstream or toxins produced by the bacteria within the bloodstream, respectively)

Both dogs and cats can serve as carriers of salmonellosis without being ill themselves.

Salmonella in Other Animals

Most other types of animals are also capable of shedding Salmonella, including horses, swine, cattle, and others. Reptiles, particularly turtles, have also been implicated as carriers of salmonellosis.

Preventing Salmonellosis For You and Your Family

There are several measures you can take that will help to ensure that you and your family do not fall prey to salmonellosis.

  • Practice good hygiene, including washing your hands thoroughly and frequently. Teach your children to do the same. Always wash your hands before handling food or drink. Always wash your hands after handling your pet's food or feces.
  • Do not eat uncooked or undercooked meat, eggs or other animal products. Unpasteurized dairy products carry a greater risk of contamination also.
  • Wash fruits and vegetables thoroughly before consumption.
  • Protect against cross-contamination in the kitchen. Keep foods apart and wash cutting boards, utensils, counters, etc. thoroughly and frequently.
  • Do not drink water which may have been contaminated with animal feces.
  • Be aware of recalls affecting both pet foods and human foods.
  • Use caution when handling pig ear dog treats. Wash your hands thoroughly after handling. Consider whether other products are more suitable for your pet.
  • If you are feeding a raw diet for your pet, be aware of the increased risk that your pet may be shedding Salmonella and take appropriate precautions (pay special attention to hand washing and proper hygiene.)
