Spatial cluster ^a) of high Salmonella Enteritidis infection rates. ^a) Results of a spatial discrete Poisson model using the SatScanTM software. Study period: January 1, 2007 to December 31, 2009. A circular scanning window containing up to 50% of the population at risk was used. Age groups (0–9, 10–24, 25–34, 35–49, and 50+ years) and sex were included as covariates to account for confounding. Significant at p ≤ 0.05.
