Distribution of non-smoothed (A) and smoothed (B) Salmonella Enteritidis infection rates in Toronto, 2007-2009 (n = 473 cases; n = 95 forward sortation areas). Direct standardization was used to calculate forward sortation area (FSA)-level annual standardized incidence rates (SIRs) of Salmonella Enteritidis infections. Spatial empirical Bayes smoothing method with 2nd order queen contiguity weights in GeoDa software (Spatial Analysis Lab, University of Illinois Urbana-Champaign, IL, USA) was used to smooth the SIRs. Maps prepared in ArcGIS 10.1 (ESRI Inc., Redlands, CA, USA)
