no coops but i tell u this , when u shoot an bleed a cow the procaine drains from cows body because its in the blood. an flows out of the meat an donest comtaminate the meat.

ummm isnt procaine injected into the muscle?

regardless of how well you drain the animal there will still be traces in the meat in particular the area it was injected into

Procaine isnt injected into a vain so it is not just contained in the blood system
