I did a little investigating on pentobarbital
The ld50 for dogs is 80mg/kg
The recommended euthanasia dose for cows is 85mg/kg
If a cow was euthanasia with pentobarbital and the drug was evenly distributed throughout the cows body (which is what my reading suggests occurs) the beef would be contaminated at 85mg/kg.
In order for a dog to get a leathal dose of pentobarbital from contaminated beef it would need to eat consume its body weight in the contaminated beef.
It just does not add up that the contamination in the canned food came from a euthanasized cow being used for the beef chunks.
Thanks for doing the investigation, I was thinking the same thing. I'm not sure the pentobarb would be evenly distributed though. It works to stop the heart and respiration and I would think that blood levels in the heart (first off the major vessels) and brain would be greatest and muscle much less due to the circulatory failure. If true, that would make the tissue levels much lower and they would have to eat even more to reach LD50.
