Abstract

Enteric infections caused by Salmonella remain a major public health burden worldwide. Poultry, particularly chickens, are known to be the main reservoir for this zoonotic pathogen. Therefore, the prevention and monitoring of Salmonella infection during the live phase may greatly reduce the contamination of poultry meat during slaughter and processing. With the ban on sub-therapeutic antibiotic usage in Europe and the increasingly strictness of the European legislation on food hygiene, passive immunization by oral administration of pathogen-specific hen egg yolk antibody (IgY) may be a useful and attractive alternative. This review offers summarized information about IgY production and the use of these antibodies for passive immunization, particularly in poultry
