The NWT in not dishonest when it conveys the interpretation: not only eating blood which is at the very least what the author meant, but also all other acts connected to blood : all unauthorized use of blood. Including blood transfusions which is a WT interpretation of what eating can also mean in addition to consuming blood orally.
But because the author does not state clearly and distinctly what that action is connected to blood, the reader must conclude for himself. Perhaps the author wants the reader to conclude that it is a Biblical axiom that any unauthorized use of blood is prohibited and that is why he left out the verb. (But that would also include using blood for scientific research, antivenom, vaccines and derivative use.) One thing for sure, not eating blood is enjoined.
