It is also interesting to note that humans can transmit salmonella to dogs:
Dogs and cats may suffer salmonellosis as a "reverse zoonosis," with infection transmitted from human-to-dog and subsequently back to other humans. Similarly, outbreaks of Salmonella infections in large animal teaching hospitals have been linked to the introduction of bacteria from infected human personnel, with subsequent spread to animals and then back to other human workers.
In one of the studies quoted on your website as part of your proof, in the first article only ten dogs were used to test for salmonella. The authors themselves state:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC339295/ Although these results are suggestive, they are not statistically significant owing to the small number of dogs studied. Larger numbers of dogs or multiple stool samples from each dog might have allowed the results to reach statistical significance. Unfortunately, the limited funding to this private clinic for this study did not allow for the inclusion of more study animals or multiple cultures from individual subjects.
And, in another study:
Since this study was an experimental trial with laboratory beagles, results may not be completely indicative of what would be experienced with owned dogs of various breeds. Determining that the raw food diet was the main source of salmonellae shedding in owned dogs would be more complicated, as they could be exposed to several other possible sources of salmonellae, including other animals; other food items, including treats; the environment; and their owners.
The information below is from your friends in Canada again. This slide has been prepared to show the dangers of raw fed foods for therapy dogs. It did a great job of skewing the results. They show the high incidence of bacteria found in 40 raw fed dogs stools, but somehow tends to downplay the amounts found in dogs fed a dry diet.
This study shows:
Raw fed dogs (40) Dry food fed dogs (156)
0 - Vanomycin resistant enterococci 1 - for Vanomycin resistant enterococci
1 - for Methicillin resistant S Aureus 8 - for Methicillin resistant S Aureus
5 - for Clostridium difficile 40 - for Clostridium difficile
19 - for Salmonella 12 – for salmonella
31 - for E Coli 32 - for E Coli
While this study may show more Salmonella and E Coli in raw fed dogs, it shows higher results for the bacteria Clostridium, Methicillin resistant S Aureus and has Vanomycin resistant enterococci. And the amount of Salmonella and E Coli, while not as high as raw fed dogs, is significant.
My conclusion is that, in your hurry to label the raw diet as the culprit, and eliminate its use from your volunteers in your program, you are only putting the spotlight on the issue that all dogs can carry pathogens regardless of diet . This could cause all dogs to be banned from use in any health facility. In essence, I see your new rule as ‘shooting yourself in the foot’. I feel in your confidence and your bias of proving a raw diet could spread pathogens, you forgot to do a full research on the issue. Salmonella is everywhere, including dry dog food, the soil, pond water and even from humans. Understand you are looking at narrow parameters that need a more careful and extensive study on how pathogens are spread and how to use sensible and effective prevention.
I don’t see a problem with allowing dogs into nursing homes, hospitals or hospices, as long as good hygiene is applied. That would include bathing the dogs, insuring therapy dogs are flea and tick free, making sure the dog’s are properly exercised (i.e., pottied) before a visit, and carrying sterilization equipment (bleach, bags and paper towels) in case of an accident. All research points out pathogens are spread by stool or saliva. That would mean not allowing the dogs to lick the clients, making sure the coats and skin are recently bathed and trusting your volunteers. Your volunteers are the backbone of your organization, and they do this loving volunteer work without compensation and give the Delta group thousands of volunteer hours. I hope you take this letter in the light it was written, in that sometimes, we need to look at any situation with more study and thought, and understand the healing, joy and encouragement dogs give so many people.
Being a patient with serious illness and being away from home often stifles recovery. Pets, as you know, bring hope, happiness and support to begin the process of healing.
I hope you rethink your position on this matter, and continue to allow your therapy dog work to bring joy to both your clients and your volunteers. My interest in researching this and writing to you is in memory to my Ch. Blackwood Dante V Lyvngwerth CD and Ch. Bourbon’s Bravo of Blackwood, two Rottweilers I owned who were the recipients of the American Rottweiler Club TRUE award, for their many hours of therapy work. And yes, they both were fed a raw diet. They both worked in the intensive care units of hospitals in Tyler, Texas, for many years.
