Abstract

Beef is considered one of the most important foods for human consumption, and Brazil stands out as the holder of the largest global commercial herd, with approximately 234.352 million head of cattle (IBGE, 2022), resulting in a high domestic consumption of this product. One of its main by-products is the liver, rich in iron, copper, zinc, and vitamins (mainly B12). In the face of this scenario, institutions and industries seek to establish guidelines to control potential diseases transmitted by these products. This study aims to identify, using real-time Polymerase Chain Reaction (qPCR), the bacteria Coxiella spp., Brucella spp., and Campylobacter spp. in bovine livers destined for slaughter.This makes it possible to identify animals with active infections, in addition to listing risk factors associated with zootechnical-sanitary aspects.
