Experimental infection of Salmonella enterica ssp. enterica serovars Panama was proceeded to establish the importance of nose-to-nose contact in the transmission among weaned pigs.

Six recently-weaned pigs were acquired from a farm previously selected, free from Salmonella spp. Isolation stalls allowing nose-to-nose contact and eliminating other transmission routes as well outside contamination were used. Three groups were formed: control, sentinel, and infected. Piglets of control and sentinel groups were not positive for Salmonella spp., however, Salmonella Panama was isolated in infected animals in rectal swabs and necropsied tissues.

It was concluded that there was not transmission by nose-to-nose contact among weaned pigs, since Samonella Panama was not isolated in the sentinel group at any moment

EFSA: factors associated with Salmonella pen positivity

29-Jul-2011
A European Union-wide baseline survey on Salmonella in holdings with breeding pigs was carried out in 2008. Now EFSA publishes the results from analyses of the associations of 19 pen- or holding- level factors and Salmonella positivity of pens in holdings with breeding pigs. Also the results from correlation analyses between Salmonella prevalence in breeding and in production holdings, from analyses of the Salmonella serovar distribution across the European Union, and from analyses of an additional within-holding prevalence study carried out by five Member States are also presented.
