Additives put tuberculosis in milk? Are you sure it wasn't the cows that had TB?

I assumed they meant that the additives made it difficult to detect that the milk had gone off and so it was easier to get sick from it.

To you point however, I don't understand how that could have increased the transmission of TB as that is caused by cows infected with Bovine TB and (AFAIK) that can't simply be detected by taste or smell.

Watching the video, it seems they assumed TB grew in milk, but according to growth requirements[1], it seems unlikely, and an unwarranted conclusion.

Still, it seems boric acid could have caused irritation, directly helping TB infect people. Also it reduced acidification, which would change bacterial population (for better or worse), and increasing bacterial loads of "spoiled" milk could weaken human defences, or not ..

I wouldn't blame Bovine TB on boric acid added to milk without further study.
