Which statement regarding Tb in humans is TRUE?

The statement that human infection with tuberculosis (Tb) can be contracted through raw dairy is true. Mycobacterium bovis, a type of bacteria that causes tuberculosis, is primarily found in cattle and can be transmitted to humans through the consumption of unpasteurized milk or dairy products. This form of transmission highlights the importance of proper food safety practices, including pasteurization, to reduce the risk of spreading this infection.

In contrast, while other routes of transmission for Tb exist, such as through respiratory droplets from coughing, the fact that raw dairy remains a potential source of infection, especially in areas where milk is not pasteurized, underscores the need for awareness and preventive measures. Understanding the routes of transmission is crucial for public health, particularly in specific populations that may consume raw dairy products.
