Resumen
Salmonella spp. es una de las principales bacterias involucradas en
enfermedades transmitidas por alimentos. De acuerdo con el National Outbreak Reporting
System (NORS) en Estados Unidos fueron reportados entre 2018-2020, 57,649 brotes de los
cuales 244 brotes eran causados por Salmonella spp., ocasionando 5.532 enfermedades,
1.037 hospitalizaciones y 6 fallecidos (CDC, 2022). Esta bacteria es capaz de formar
biopelículas; la cual es una comunidad de microorganismos con células unidas
irreversiblemente a un sustrato, e incrustadas en una matriz de sustancias poliméricas
extracelulares (EPS) (Donlan & Costerton, 2002). Las biopelículas brindan protección frente
a agentes desinfectantes y diferentes tipos de estrés encontrados en ambientes de
procesamiento de alimentos (H. Steenackers et al., 2011). Diferentes estudios han
demostrado la capacidad de Salmonella spp. de formar biopelículas en acero inoxidable, el
cual es una de las superficies abióticas más utilizadas en la industria alimentaria por su gran
resistencia (Lee et al. 2020). En esta línea, se ha evidenciado que biopelículas de Salmonella
spp. formadas en acero inoxidable son difíciles de eliminar con desinfectantes comúnmente
utilizados en la industria alimentaria (H. Steenackers et al., 2011).
Salmonella spp. it is one of the main bacteria involved in foodborne illnesses. According to the National Outbreak Reporting System (NORS) in the United States, between 2018-2020, 57,649 outbreaks were reported, of which 244 outbreaks were caused by Salmonella spp., causing 5,532 illnesses, 1,037 hospitalizations, and 6 deaths (CDC, 2022). This bacterium is capable of forming biofilms; which is a community of microorganisms with cells irreversibly attached to a substrate, and embedded in a matrix of extracellular polymeric substances (EPS) (Donlan & Costerton, 2002). Biofilms provide protection against sanitizing agents and different types of stress found in food processing environments (H. Steenackers et al., 2011). Different studies have shown the ability of Salmonella spp. to form biofilms on stainless steel, which is one of the most used abiotic surfaces in the food industry due to its great resistance (Lee et al. 2020). Along these lines, it has been shown that Salmonella spp. formed in stainless steel are difficult to remove with disinfectants commonly used in the food industry (H. Steenackers et al., 2011).
