There has been some really useful advice here.
For me and my tuppence worth, is a bit of a combination of whats been said already. And again, simply my opinion.
1: There are a lot of legitimate concerns surrounding E Coli, Listeria and Salmonella....however, even if this is in the meat and it passes through to the stool, it is only dangerous to humans if the have weakened auto immune systems, and even then if proper hygiene rules will diminish this. Also remember dogs lick and chew nearly everything they can get to that smells funny, so these pathogens might likely be in the stool in any event.
2: Ingredients will be a likely indicator of the likelihood of pathogens. I know this as we are developing and launching a Raw Food, and Irish regulations require testing on ALL production batches, and we have found problematic ingredients such as tripe for instance which have very high bacterial counts. Even washed tripe has issues, and while we are looking at ways of further cleaning tripe to meet the 5000 endobacterial counts required under EU legislation, we wont include it in our mixes until this is fixed.
3: You can always do it yourself. A cheap mincer for the bones, and some clever shopping means you have control over the freshness and quality of the meat your dog is eating. It is a simple enough process of (again in my opinion) 60-70% meat, 10-15 % bone 5-10% offal (Liver and kidney can be boughts in shops) and vegetables such as finely chopped carrots, broccoli and peas). All that companies like mine are doing is preparing for those who dont have the time or money. (we produce in bulk so it is cheaper)
4: You can always cook it. This kills most pathogens. Some dogs dont like raw, There is also an argument that the bacteria in the gut that process raw meat diminish over time when kibble and cooked meat is digested. just DONT cook a product with tripe...it will stink your house. Top four feeds for your dog in mine and Dr Karen Beckers opinion 1: Home prepared Raw, 2: Commercial Raw 3: Fresh Home Cooked 4: Fresh Commercial cooked. While I am a producer of a raw dog food, my Rottweiler eats our food cookedand he is in superb condition, we are preparing a cook in the bag solution for people who want to do this. Its not as good as raw, but it is very very close if you dont overcook. You are now feeding Fresh...second only to Raw.
Finally, if this is something you still cant do, products such as Orijen and Acana are now producing freeze dried and traceable kibbles which are as close to the Raw or Fresh experience but they are pricey.
I hope this helps, and best wishes with the decision.
