Listeriosis and your pets - the lowdown

Hill’s Pet Nutrition South Africa addresses pet parents' Listeriosis concerns

The latest nationwide Listeria outbreak has naturally got pet parents concerned about what they should and shouldn’t be feeding their pets. Listeriosis is a serious but treatable disease caused by Listeria monocytogenes, which is widely distributed in nature and can be found in soil, water, and vegetation. “Risks of infection in pets, while possible, is less likely. Pets with underlying disease conditions, weakened immune systems and those who are older are at an increased risk,” explains Dr. Guy Fyvie, Nutritional Advisor at Hill's Pet Nutrition, South Africa.

Discussing raw food diets vs prepared food choices, is a bit like discussing politics or religion at a dinner party, but when it comes to Listeriosis you need to know the facts. The American Veterinary Medical Association and the American Animal Hospital Association, as well as the FDA, have all come out with official positioning statements cautioning against raw food diets.

In one study scientists evaluated 480 samples of dry and semi moist food and found only two incidences of contamination. One was positive for Salmonella and the other for Listeria greyii. This comes to a 0.4% contamination rate. On the other hand, of the 196 samples of raw dog and cat food, a total of 88 were found to be contaminated — 65 for Listeria, 15 for Salmonella, and 8 for E.Coli – a 45% contamination rate.

Dr. Fyvie says you can prevent your pets from exposure to Listeria infections by following these tips:

  • Pay attention to the news. Any food that is unsafe for you is also unsafe for your pet. Make sure you discard contaminated products properly, you don’t want your pet finding the item later.
  • Stick to safe treats. Stick to nutritious Hill’s stews rather than giving your pet viennas, sausages or cold meats as a reward.
  • Cook meat thoroughly. If you feed your pet meat make sure it’s been cooked, no matter what it is. Listeria is very heat sensitive, a core temperature of 70°C will kill the bacteria.

If you’re worried your pet may have come into contact with any Listeria contaminated products; then look out for the following symptoms:

  • Diarrhoea
  • Nausea
  • Fever
  • Vomiting
  • Weakness
  • Lack of co-ordination

As a pet parent you may be wondering if your pet can pass the disease onto you? Dr. Fyvie says this is highly unlikely, however. “You have a greater chance of contracting Listeriosis from pets eating raw diets.”

According to Dr. Fyvie pet parents have no need to be concerned if their pets’ food is made by a reputable manufacturer under strict quality control measures such as Hill’s Pet Nutrition. “Hill’s ethical sourcing of raw ingredients from limited certified vendors and the processing and controls in place during manufacture, packaging and shipment means the chances of Listeriosis is practically non-existent.”
