For the control of mobile Salmonella presenting a high zoonotic risk and also involving property damage through mortality, a National Program was implemented in Romania to control mobile Salmonella infections in breeding hens, which includes relevant serovars represented by S. enteritidis, S. infantis, S. hadar, S. typhimurium and S. virchow and relevant serovars represented by S. enteritidis and S. typhimurium for laying hens and broiler chickens. The faeces samples were collected with a frequency established by the Community legislation while the program aimed at reaching a prevalence of 1% or less of the flocks with a confidence interval (confidence limit) of 95% for breeding hens and broiler chickens and up to 2% for flocks of laying hens. Following the study conducted, 655 strains of Salmonella enterica subsp. Enterica were isolated. For the breeding hens, serovar S. enteritidis had the highest incidence - 15 strains were identified, for serovar S. typhimurium only one strain was isolated, while the other relevant serovars represented by S. infantis, S. hadar and S. Virchow were not identified. For the laying hens, S. enteritidis had the highest incidence - 19 strains were identified, while for serovar S. typhimurium 5 strains were identified. In farms of broiler chickens S. enteritidis had the highest incidence as well - 38 strains were identified, while serovar S. Typhimurium was not identified.
