Irrelevant. The nitrate is what is toxic in that compound, not the silver. That is like saying that nitrogen is poisonous because cyanide is.

It is not possible that death can be caused by silver in silver nitrate because the nitrate is quite toxic, and silver almost nontoxic. You would be dead many times over from the nitrate before silver had any appreciable effect. That is like saying that 5 mg of carbon will kill a man, by testing with HCN, cyanide which is very poisonous. Marshall -- The Silver List is a moderated forum for discussing Colloidal Silver.
