Resumen
Los alimentos vegetales como las verduras y las hortalizas son una de las
principales vías de transmisión de microorganismos patógenos, ya que se trata de
un cultivo agrícola y su consumo puede ser en crudo, convirtiéndolos en alimentos
más susceptibles de contaminación microbiana. En este estudio se ha evaluado la
resistencia a diferentes tipos de antibióticos y biocidas, empleados frecuentemente
en la industria alimentaria, frente a cepas seleccionadas de zanahoria y jengibre. De
acuerdo con los resultados obtenidos, se han hallado las bacterias Pseudomonas
baetica (en zanahoria) y Serratia liquefaciens (en jengibre). Ambas han manifestado
resistencia frente a los antibióticos cefalosporinas (betalactámicos) de estudio, y
frente a cloranfenicol. P. baetica también ha presentado resistencia a eritromicina,
sulfonamida y al biocida clorhexidina. S. liquefaciens además ha mostrado
resistencia frente a meropenem.
Vegetable foods in general are one of the main routes of transmission of pathogenic microorganisms, since it is an agricultural crop and its consumption can be raw, turning them into foods more susceptible to microbial contamination. In this study, resistance to different types of antibiotics and biocides, frequently used in the food industry, was evaluated against selected strains of carrot and ginger. According to the results obtained, the bacteria Pseudomonas baetica (in carrot) and Serratia liquefaciens (in ginger) have been found. Both have shown resistance to the antibiotics cephalosporins (beta-lactams) study, and against chloramphenicol. P. baetica has also shown resistance to erythromycin, sulfonamide and the biocide chlorhexidine. S. liquefaciens has also shown resistance to meropenem.
