Abstract

Introduction: Salmonellosis is the second most reported gastrointestinal disease and the first cause of foodborne outbreaks in Spain and in the EU. The aim of this study is to describe the temporal trend and epidemiological characteristics of salmonellosis in Spain during the pre-pandemic period 2013-2019, using three different sources.

Methodology: A retrospective descriptive observational study was carried out, in which cases and epidemic outbreaks of salmonellosis reported to the Spanish Epidemiological Surveillance Network, as well as information related to the data registered in the Minimum Basic Data Set of Hospital Discharges between 2013 and 2019 were studied.

Results: A total of 60,771 cases, 2,233 outbreaks and 24,096 hospital discharges of campylobacteriosis were reported. The Cumulative Incidence of individualized cases increased until 2016, although 2018 was the year with the highest incidence. The Cumulative Period Incidence was higher in men than in women, both for individualized cases (27.76 and 25.05, respectively) and for hospital discharges (8.32 and 6.50, respectively). In the individualized cases, the highest incidence occurred in the group of 1 to 4 and in hospital discharges in children under one year of age. The number of cases, outbreaks, and hospital discharges was higher in the warmer months. The food item most frequently reported in foodborne outbreaks was egg, and the household was the most frequent setting reported.

Conclusions: Incidence of salmonellosis at the national and international level remains high. Eggs and their derivatives are the foods most often associated with food outbreaks. The joint analysis of multiple data sources improves epidemiological surveillance by providing complementary information relevant to decision-making.

Keywords: Salmonellosis, outbreak, hospitalization, epidemiological surveillance, egg.
