The occurrence of foodborne diseases has been a matter of discussion over the last years due to the worldwide concern with strategies for their control and for ensuring that safe food products reach the consumer. Salmonella spp. is among the most widespread microorganisms in nature, having man and animals as main natural reservoirs. With occurrence of regional serotypes causing salmonellosis, this pathogen is considered one of the main agents responsible for outbreaks of foodborne disease in the developing countries. The increasing incidence of salmonellosis caused by contaminated food has shown that, despite the recent technological improvements, this problem still occurs in all countries. Cattle and poultry are the main responsible for the transmission of this pathogenic agent. Due to its wide distribution in animals, the existence of asymptomatic carriers and its presence in foodstuff and in the environment Salmonella spp. represents a significant public health problem worldwide calling for permanent control programs and eradication strategies.
