Poultry are kept and raised in various climates, within different housing and management systems, and are fed a diverse range of raw materials.
They are also subjected to various vaccination and biosecurity procedures. Despite these differences, salmonellosis remains one of the main zoonoses impacting human health globally. A well-structured, conceptual approach to monitoring the environment and assessing the risk of Salmonella incidence can help reduce environmental risks. Additionally, by increasing the birds’ resistance to contamination, poultry operations can further mitigate the impact of Salmonella infections.
Anti-bacterial activity in the gizzard
Salmonella enterica is widely present and is a threat to humans.
Poultry can become infected with Salmonella via horizontal or vertical transmission, so the traditional approach of focusing on only environmental contamination is not effective. To keep poultry Salmonella free – even when the bacteria might be present in the environment – poultry need to be made less sensitive to Salmonella infection. As the main route of infection is the gastrointestinal tract, killing the pathogenic bacteria as soon as it enters the gastrointestinal tract is effective
