Opinion of the Scientific Panel on Biological Hazards on the requests from the Commission related to the use of vaccines for the control of Salmonella in poultry
European Community legislation on food hygiene and control of zoonoses includes a number of provisions that seek to control and prevent the Salmonella contamination of foodstuffs.
The basis for the successful control of Salmonella infections in poultry farms is good farming and hygiene practices and the testing and removal of positive flocks from production. Vaccination of chickens is regarded as an additional measure to increase the resistance of birds against Salmonella exposure and decrease shedding of Salmonella.
Salmonella vaccines currently authorized for use in poultry in the Member states have been authorised on the basis of the mutual recognition procedure. Both live and inactivated Salmonella vaccines are available. At the moment, the extent of vaccination in different Member States differs considerably.
The panel concluded that vaccination is useful in control programs targeting S. Enteritidis and S. Typhimurium. The use of vaccination and different vaccines (live and/or inactivated) is dependent on the prevalence of these serovars in the flock, and the type of flock involved (breeders, layers or broilers).
