Resumo: | Foodborne diseases (FBD) present high prevalence worldwide and more than 250 types have been reported. The main agents are Staphylococcus aureus, Escherichia coli, Salmonella and certain parasites. The habit of consuming foods sold in street markets in the city of São Paulo exposes consumers to the risk of acquiring FBD. 25 samples of vinaigrette salad were collected in the central, northern, southern, eastern and western regions of the city of São Paulo, Brazil. The samples were inoculated in selective, enriched culture media and biochemical analyses were performed. Bacterial and fungal growth occurred in all samples. The microorganisms detected were E. coli (64%), Enterobacter (60%), S. aureus (52%), Klebsiella (40%), Proteus sp. (32%), Shigella sp. (28%), Citrobacter sp. (16%), Edwardsiella sp. (12%), Alcaligenes sp. (8%), Serratia sp. (8%), Salmonella sp. (4%), Pseudomonas sp. (4%) and; 72% were positive for aflatoxins. Twelve species were identified, 50% of which can cause FBD. S. aureus and fecal coliforms can cause FBD, while Alcaligenes sp. can cause nosocomial infections and Edwardsiella sp. can cause hepatic abscess, meningitis and septicemia. Aflatoxins may cause mycotoxicoses and liver cancer. Therefore, inspections, and prevention and awareness measures should be reinforced to minimize the risks of contracting FBD from foods sold in street markets in the city of São Paulo. |

Los principales agentes son Staphylococcus aureus, Escherichia coli, Salmonella y algunos parásitos. El hábito de consumir alimentos vendidos en mercados abiertos de la ciudad de São Paulo expone a los consumidores al riesgo de adquirir ETA. Se recolectaron 25 muestras de ensalada de vinagreta en las regiones central, norte, sur, este y oeste de São Paulo, Brasil. Las muestras se inocularon en medios de cultivo enriquecidos selectivos y se realizaron análisis bioquímicos. Se produjo crecimiento de bacterias y hongos en todas las muestras. Los microorganismos detectados fueron E. coli (64%), Enterobacter (60%), S. aureus (52%), Klebsiella (40%), Proteus sp. (32%), Shigella sp. (28%), Citrobacter sp. (16%), Edwardsiella sp. (12%), Alcaligenes sp. (8%), Serratia sp. (8%), Salmonella sp. (4%), Pseudomonas sp. (4%) y 72% fueron positivos para aflatoxinas. Se identificaron doce especies, el 50% de las cuales pueden causar ETA. S. aureus y coliformes fecales pueden causar ETA, mientras que Alcaligenes sp. puede causar infecciones nosocomiales y Edwardsiella sp. puede causar absceso hepático, meningitis y septicemia. Las aflatoxinas pueden causar micotoxicosis y cáncer de hígado. Por lo tanto, se deben reforzar las inspecciones y las medidas de prevención y sensibilización para minimizar los riesgos de contratar ETA en los alimentos vendidos en los mercados abiertos de la ciudad de São Paulo.As doenças transmitidas por alimentos (DTA) apresentam alta prevalência em todo o mundo e mais de 250 tipos foram relatadas. Os principais agentes são Staphylococcus aureus, Escherichia coli, Salmonella e alguns parasitas. O hábito de consumir alimentos vendidos em feiras livres da cidade de São Paulo expõe o consumidor ao risco de adquirir o DTA. 25 amostras de salada de vinagrete foram coletadas nas regiões centro, norte, sul, leste e oeste da cidade de São Paulo, Brasil. As amostras foram inoculadas em meios de cultura enriquecidos seletivos e análises bioquímicas foram realizadas. O crescimento bacteriano e fúngico ocorreu em todas as amostras. Os microrganismos detectados foram E. coli (64%), Enterobacter (60%), S. aureus (52%), Klebsiella (40%), Proteus sp. (32%), Shigella sp. (28%), Citrobacter sp. (16%), Edwardsiella sp. (12%), Alcaligenes sp. (8%), Serratia sp. (8%), Salmonella sp. (4%), Pseudomonas sp. (4%) e 72% foram positivos para aflatoxinas. Doze espécies foram identificadas, 50% das quais podem causar DTA. S. aureus e coliformes fecais podem causar DTA, enquanto Alcaligenes sp. podem causar infecções nosocomiais e Edwardsiella sp. pode causar abscesso hepático, meningite e septicemia. As aflatoxinas podem causar micotoxicoses e câncer de fígado. Portanto, inspeções e medidas de prevenção e conscientização devem ser reforçadas para minimizar os riscos de contrair DTA em alimentos comercializados em feiras livres da cidade de São Paulo.Research, Society and Development2021-09-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1973810.33448/rsd-v10i11.19738Research, Society and Development; Vol. 10 No. 11; e504101119738Research, Society and Development; Vol. 10 Núm. 11; e504101119738Research, Society and Development; v. 10 n. 11; e5041011197382525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/19738/17797Copyright (c) 2021 Sheila Chagas Mendes; Juliane Vismari de Oliveira; Katharyna Cardoso de Gois; Jorge Luiz Pinto; Fernando Luiz Affonso Fonseca; Alípio de Oliveira do Carmo; Francisco Sandro Menezes-Rodrigues; Flávia de Sousa Gehrkehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Mendes, Sheila Chagas Oliveira, Juliane Vismari deCardoso de Gois, Katharyna Pinto, Jorge LuizFonseca, Fernando Luiz Affonso Carmo, Alípio de Oliveira do Menezes-Rodrigues, Francisco Sandro Gehrke, Flávia de Sousa 2021-10-23T19:01:11Zoai:ojs.pkp.sfu.ca:article/19738Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:39:34.965927Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
