There were 1,978 incidents of Salmonella in 2011 which represents a decrease of 15.6% compared with 2010 (2,343 incidents). These comprised 1,771 incidents from statutory species (712 incidents from cattle, 410 incidents from chickens, 282 incidents from turkeys, 182 incidents from pigs, 88 incidents from sheep, 43 incidents from horses, 27 incidents from ducks, 14 incidents from pigeons, seven incidents from pheasants, five incidents from partridges, one incident from deer) and 207 incidents from non-statutory species.
There were falls in the number of incidents from cattle (19.7% lower than in 2010), sheep (47.9% lower than in 2010), chickens (13.5% lower than in 2010) and ducks and geese (65.4% lower than in 2010) and
increases in the number of reports from pigs (by 5.2%) and turkeys (by 18.0%).
A total of 5,685 pig submissions were received by AHVLA in 2011, an increase on 5,202 in 2010 and 5,334 in 2009. 1,596 diagnostic pig submissions (which generate the bulk of Salmonella incidents in pigs) were received in 2011, which is up slightly on 2010 (1,574).
Salmonella Typhimurium remained the most commonly found serovar, associated with 77 incidents in the year. This is however a reduction on the 99 S. Typhimurium incidents reported in 2010 and maintains the general decline in incidence of this serovar seen over the past decade. No Salmonella Enteriditis was isolated from pig submissions during the year.
Salmonella Derby was the fourth most common serovar in 2011 (13 incidents), and has consistently accounted for between 4% and 8% of incidents annually, over the last five years. Several other serovars accounted for small numbers of incidents each, including S. Bovismorbificans (6 incidents), S. Kedougou (a feed associated serovar, 4 incidents), S. London (4 incidents) and S. Reading (3 incidents). Salmonella Panama was identified in four incidents in 2011.
