Cattle industry and zoonotic risk.

The intensive farming of dairy and beef cattle has elicited a decrease in the herds and an increase in the number of animals per herd. The high concentration of cattle and the movement of the animals among herds has led to an increase in the health risks. In this context we have to consider the role of microbial agents of zoonoses, such as bacteria, parasites, and in some cases viruses. Notably, foodstuffs, such as meat, milk and dairy products, are the main sources of zoonoses of bovine origin. In particular, raw milk must be considered at high risk for trasmission of pathogens from cattle to humans. The European Regulation concerning food safety provides specific requirements for animal products and in bovine health management. Given the direct responsibility of the producer, the adoption of a self-regulation regimen on animal health, dairy and meat products must be planned by farmers.
