An outbreak of S.Typhimurium occurred in several towns and cities in the province of Castellon (Spain) between 23 February and 27 May 2011. On April 5, the microbiology laboratory of a hospital in Castellon alerted the health authorities to the increase in S.Typhimurium isolated in fecal culture of children with gastroenteritis. The serotype and phage-type of 83 positive cases of S.Typhimurium isolated in these period included 49 monophasic/biphasic S.Typhimurium phage type 138, phage type 193, S.Derby, and 34 other S.Typhimurium phage-types. The median of age of patients was 4 years with a range of 0.6–80 years, and the 18% of patients were hospitalised. Two incident matched case–control studies were carried out; the first with S.Typhimurium phage type 138, 193, and S.Derby cases and the second with the other cases. The two studies found that the consumption of brand X dried pork sausage, purchased in a supermarket chain A, was associated with the disease (matched Odds Ratio [mOR] = 13.74 95% Confidence Interval [CI] 4.84–39.06 and mOR = 8.20 95% CI 2.32–28.89), respectively). S.Typhimurium phage type 193 and S.Derby were isolated in the food taken from the household of two patients and from the supermarket chain's A central warehouse. The pulsed-field gel electrophoresis study confirmed the similarity of the strains from the patients and the food. On May 25 2011, a national food alert led to the withdrawal of the food from the chain A and the outbreak ended.
