Is it contagious to eat with someone who has tuberculosis?

It is possible to be infected by eating with a person who has tuberculosis. Tuberculosis can be transmitted mainly through respiratory droplets. Intestinal tuberculosis can be contracted by eating milk and food containing Mycobacterium tuberculosis, and tuberculosis contracted by eating together is not transmitted through the digestive tract but through the respiratory tract. When eating together, people are in close contact with each other, and sputum-positive TB patients can discharge Mycobacterium tuberculosis into the air by talking, sneezing, coughing, etc., forming droplet nuclei, which are suspended in the air or floating with dust in the sputum. When people who eat together inhale droplet nuclei and dust, it can lead to tuberculosis infection, but in general, active tuberculosis and sputum-positive people are isolated or treated with anti-tuberculosis and have fewer chances to eat together with people. If a person who is sensitive to anti-tuberculosis drugs can make sputum negative in 1-2 months, the infectiousness is minimal and meals can be shared.
