You can also be a silent carrier of TB and that happened in families AND you can get TB from Cows which is why they started testing cattle for TB back in the 1920s and 1930s for it. They recognized that the bacillus can be passed that way too. There is a rarer form but still transmissible by chickens.
However, mostly respiratory droplets is what causes TB transmission and droplets on food handling too.
When they recognized how TB was transmitted, it was also a reason to stop spitting in train and trolley cars. A great outcry of freedom and rights was raised but public health won that one, at least here in America. Public spitting is still a thing in other parts of the world and those parts still have TB problems among other things.
