Which ideology in Ethiopia might contribute to TB spread?

The correct answer highlights the consumption of raw milk and meat as a contributing factor to the spread of tuberculosis (TB) in Ethiopia. This is particularly relevant in the context of zoonotic diseases, which are transmitted from animals to humans. In many regions, especially those with significant livestock farming, the consumption of unpasteurized milk and undercooked meat can lead to the transmission of Mycobacterium bovis, the bacterium that causes bovine TB.

In Ethiopia, where dairy products and local meat are common in the diet, there is a higher risk of acquiring and subsequently spreading TB through these food sources. The risk is amplified in settings where agricultural practices do not prioritize food safety measures, such as pasteurization. Consequently, individuals consuming raw dairy or meat without sufficient cooking may become infected, thereby contributing to the overall spread of TB within communities.

On the other hand, while the other options may have their own public health implications, they do not directly relate to the zoonotic transmission of TB in the same way as the consumption of raw products. For instance, while cattle trading can impact disease spread, it primarily affects animal health rather than directly contributing to human TB infection through dietary practices.
