Resumen:
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. (C) 2015 Elsevier Espana, S.L.U. and
