Unfortunately, the simple answer is: we just don't know.
That said, Franco the owner of Sausage Making is an experienced curer and sausage-maker and says to replace the salt and cure with the All Purpose Curing Salt, so we assume that the level of nitrite/nitrate is around 0.5% for each to give levels within the EU rules.
From anywhere else I'd be dubious, but I know that Franco knows his stuff.
Sorry not to be of more help.
