Hi Guy,
It seems that you have been given recommendations by the medical professionals that understand your situation.
Considering that raw diets in dogs has been associated with some fairly serious heath issues in people I understand why your vet is concerned. These types of events are very infrequent but may be of higher frequency in immunosurpresed individuals.
Consider not only food handling hygiene but also bacterial contamination in the environment. For example, a dog finishes the meal and then wipes their face on the couch. Bacterial transfer can occur. Some time ago I read a paper in which the authors cultured out the contents of vacuum cleaner bags. In raw fed home 10% of the time they grew out Salmonella. Salmonella was also found in vacuum cleaner bags in kibble fed dogs but at a lower occurrence. The numbers tested were too small to do a statistical analysis but it severs as a eye opener as to the extent of bacterial transfer.
My BIL didn’t make it to organ transfer but was going through the process. The dog’s base diet was discussed and dog chews as well….no animal parts like bully sticks, pig ears etc. Everything offered to the dog had to have gone through a “kill” step and then be sealed from potential contamination.
