Salmonella and Pet Food Recalls

Bacteria reside in all types of dog food including raw, home-cooked and commercial diets. There are, of course, hundreds of strains of bacteria, some harmful and some helpful within the body. When handling any type of pet food it is extremely important to use the same food safety handling methods that you would use for human food. This includes not leaving food at room temperature (cooked or raw), washing surfaces and hands with warm, soapy water and discarding food that looks or smells off.

The most common bacteria for concern in the pet industry are strains of salmonella which can cause salmonella poisoning (salmonellosis) and enteritis (inflamed intestine). Although dogs seem to handle most bacteria fairly well, immune compromised dogs and humans are at risk. It is for this reason that a large dog food company called Diamond Pet Foods recently put out a recall on a large number of their products. As I have been travelling (I moved home to Canada this weekend) I was not aware of this recall until I received a phone call from my local Costco. Kirkland, the Costco brand of dog food and Taste of the Wild, have been included in the recall that is affecting hundreds of pets, owners and retailers across North America. A detailed account of this recall can be found at Food Safety News which also includes the extensive list of brands and affected products. This salmonella outbreak, as of today, has put 14 people in the hospital.

Keep in mind when reading this article that all the brands listed in this recall come from ONE plant in South Carolina. I find it interesting and certainly not surprising, that one plant can be producing food for so many various type of branded dog food.

The main problem associated with salmonella is that while the healthy immune system of a dog can handle salmonella, they could become subclinical carriers. When dogs ingest salmonella they either succumb to salmonellosis (click here for symptoms) or propel the bacteria through their digestive tract (the case in most dogs). A healthy dog will attack salmonella in the large intestine with a combination of cell mediated immune factors and gut-friendly bacteria. These molecules prohibit the salmonella from multiplying and expel it in the feces. It is for this reason that most healthy dogs will test positive for salmonella cultures.

A subclinical dog will not be able to entirely rid itself of the salmonella bacteria, thus continually shedding the strain in its feces, mucous and saliva. This poses a problem for two reasons; one, humans (especially children and seniors) are at a higher risk of ingesting the shedded bacteria and two, if this subclinical dog comes under stress, its body may become overwhelmed by the bacteria and fall ill.

Sounds scary right? Well it is and it isn't. The fact is that most of us have been working with salmonella our entire lives without realizing it. Due to our health and hygienic practices (such as washing your hands after picking up dog poo) we manage the bacteria in our lives and if ingested, rely on our immune systems and gut bacteria to fight off infection. With that in mind, I've composed a list of food safety practices to use when handling your dogs food.

· always wash your hands after handling any dog food

· refrigerate all fresh foods used to feed your dog and discard untouched food.

· if you have children be diligent about cleaning up after your dog and removing food bowls after feeding (this is really the tip of the iceberg when it comes to children and dogs)

· wash your dogs bowl, serving utensils and other preparatory equipment after every use with hot, soapy water.

· store dry foods properly. Keep in cool locations or in the freezer. Limit oxygen exposure. Discard untouched food or kibble that is wet or warm (a breeding ground for salmonella)

· if you're worried about bacterial contamination in meat that you are feeding ,flash fry the outer surface or dip in boiling water

· listen to your dog, if he or she seems sick, go to your veterinarian!

Although raw food diets typically get a bad rap for exposing your dog and family to harmful bacteria, the truth is that bacteria are everywhere. Using common sense and practical methods will help ensure the levels of bacteria stay below a dangerous level and keep your family safe.
