Although in 2020 the country's Gross Domestic Product (GDP) declined 4.1% compared to the previous year, the participation of livestock in the same period increased its representation from 8.4 to 10%. It is estimated that Brazil's contribution to the world food market has grown from 20.6 billion to 100 billion and the prospects are for greater increases for the coming years. In terms of people fed, the numbers were 800 million people. Thus, it is important to avoid the occurrence of illnesses, especially those transmitted by food. Included in this group are zoonosis, defined as diseases transmitted by animals to humans, which can be bacterial, viral or parasitic. According to the World Organization for Animal Health, 60% of human infectious diseases are zoonotic and 75% of emerging infectious disease agents in man is of animal origin. Among the main ones are the taeniasis-cysticercosis complex and tuberculosis. They are a global public health problem and prevent the efficient production of food. This work is a literature review that aimed to discuss the causative agents of these diseases, as well as the characteristics, contamination in food and possible measures for its control.
