Salmonelloses in the State of Rio Grande do Sul, southern Brazil, 2002 to 2004

Abstract

Salmonella has been identified as the main aetiological agent responsible for foodborne diseases in several countries worldwide, including Brazil. In the State of Rio Grande do Sul (RS), southern Brazil, previews studies analysed official foodborne illnesses data, identifying Salmonella as the main bacterial agent of foodborne diseases during the period of 1997 to 2001. The present study aimed to analyse the official epidemiological data on salmonelloses occurred in the State of RS, during the period of 2002 to 2004. Even though data on recent salmonelloses were available, only data concerning the period comprising in 2002 to 2004 were analysed because the official worksheet records presented more consistent information about the salmonellosis outbreaks. Results indicated that, among the 624 foodborne outbreaks officially investigated, 202 (32.37%) were confirmed as salmonellosis. Among them 23,725 people were involved, 4,148 became sick, 1,878 were hospitalized and one person died. The season with the highest incidence of salmonelloses was spring, and the most affected age group was composed of people aged between 20 to 49 years old (56.66%). Animal origin foods - especially eggs and meat products - were very often involved with the outbreaks, however homemade mayonnaise was identified as the main food vehicle for salmonelloses (53.51%). The majority of the cases occurred inside private homes (55.81%) and food services (12.1%), and the main factors contributing to the occurrence of the outbreaks were the consumption of products without sanitary inspection (26.7%) and exposure of food at room temperature for more than two hours (18.58%). Similarly to what was previously reported for the period of 1997 to 2001, Salmonella spp. was the most prevalent foodborne disease agent in the State of RS during the years of 2002 to 2004.

Spatial-temporal epidemiology of human Salmonella Enteritidis infections with major phage types (PTs 1, 4, 5b, 8, 13, and 13a) in Ontario, Canada, 2008–2009

“…Previous studies identified private homes as an important exposure setting for sporadic, home-based foodborne infections [ 42 – 44 ]. Several predisposing factors of home-based infections have been identified, including inappropriate food handling, storage, and food preparation [ 42 , 43 ]; consumption of contaminated raw and undercooked foods [ 42 ]; and person-to-person [ 44 ] and animal-to-person [ 45 , 46 ] transmission.…”

Perfil epidemiológico das principais doenças veiculadas por alimentos

“…Cabe destacar que a própria maionese pode propiciar elevada multiplicação microbiana, tanto a caseira como a industrializada, uma vez que tanto o ovo como a batata apresentam características de meio de cultura, ou seja, acabam sendo alimento para as bactérias se multiplicarem, devido às suas propriedades nutritivas (intrínsecas) (Wagner, Silveira, & Tondo, 2014;Capalonga et al, 2014).…”

ESTUDO DO PERFIL EPIDEMIOLÓGICO DOS SURTOS DE DOENÇAS DE TRANSMISSÃO HÍDRICA E ALIMENTAR NO RIO GRANDE DO SUL: uma revisão dos registros no Estado

“…Dessa forma, esses motivos podem contribuir para a maionese caseira estar frequentemente envolvida com surtos de origem alimentar em vários países (STEIN-ZAMIR et al, 2009;DI PINTO et al, 010;FICA et al, 2012;NORTON et al, 2012). Em outros estudos, a maionese caseira foi identificada como o principal veículo envolvido com salmoneloses no estado do Rio Grande do Sul (COSTALUNGA; WAGNER et al, 2014;BARTZ, 2014;CAPALONGA et al, 2014).…”
