BERROCAL MARTINEZ, María Teresa; RUIZ-JUAREZ, Daniel; GUTIERREZ-ROJAS, Mónica  e  OLIVARES-OROZCO, Javier. Epidemiological behavior of Salmonella sp. in plant-based foods by intercontinental region. Rev. Mex. Cienc. Agríc [online]. 2023, vol.14, n.1, pp.109-121.  Epub 19-Jun-2023. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v14i1.2966.

The epidemiological behavior and specific serotypes of Salmonella sp. in plant-based foods are represented by state, country, and intercontinental region. Histograms show incidences of outbreaks in the population of Africa, Europe and North America, spatial distribution of serotypes and the cumulative relative frequency curve. The foodborne diseases were due to Salmonella Infantis, S. Derby, S. Enteritidis, S. 1,4,[5],12:i:-, S. Agona, S. Panama, S. Typhi, S. Braenderup, S. Typhimurium, S. Newport, S. Saintpaul, S. Poona, S. Abony, S. Urbana, S. Adelaide and S. Uganda. On the African continent, the epidemiological behavior of S. enterica showed significant statistical differences (p≤ 0.0001), with cumulative prevalence for North Africa (49.9%), East Africa (12%), South Africa (3%), and West and Central Africa (13%), in contrast to the incidence observed for non-typhoid S. In Europe, the epidemiological behavior of Salmonella sp. by year of study showed statistically significant differences (p≤ 0.0001) in the observed incidence among 28 countries, also, the Fi of outbreaks of Salmonella sp. was higher in the last year. Between the United States and Mexican states, significant differences (p≤ 0.0001) were also observed in the incidence of the number of epidemiological outbreaks by year. However, as of 2019, a decrease in the epidemiological curve was observed. Among the regions of Africa, Europe and North America, the epidemiological behavior of Salmonella sp. presented incidences of 4.08, 30.82 and 65.1% respectively, due to the consumption of contaminated plant-based foods.
