Contaminación enterobacteriana de alimentos cárnicos consumidos en la FES Iztacala y su periferia

Abstract

<div>Las enfermedades transmitidas por alimentos son aquellas que se originan por la ingesti&oacute;n de alimentos contaminados en cantidades suficientes para afectar la salud. El objetivo de esta investigaci&oacute;n fue identificar enterobacterias en alimentos c&aacute;rnicos consumidos en establecimientos y puestos ambulantes cercanos a la Facultad de Estudios Superiores Iztacala (FESI). Metodolog&iacute;a: estudio tipo descriptivo, transversal y prospectivo. Se seleccionaron aleatoriamente 10 sitios con venta de alimentos. Los procedimientos microbiol&oacute;gicos estuvieron basados en las normas NOM-114- SSA1-1994, NOM-065-SSA1-1993 y NOM-092- SSA1-1994. Para la detecci&oacute;n de enterobacterias en c&aacute;rnicos, se llevaron a cabo dos fases: etapa presuntiva (pruebas bioqu&iacute;micas) y la etapa confirmativa en donde se emple&oacute; como medio de</div><div>cultivo caldo lactosado bilis verde brillante. En la prueba de mes&oacute;filos, el 90% de los cultivos fueron positivos; en coliformes obtuvimos un 42% de positividad; coliformes fecales 64%. Estos resultados indican la presencia de carga enterobacteriana en el 95% de las muestras estudiadas; el 25% pertenece al g&eacute;nero Salmonella; en tinci&oacute;n de gram, 95% fueron gramnegativas. El entorno influye directamente en la salud de las personas, ya que un inadecuado manejo en la preparaci&oacute;n de alimentos puede conducir al incremento en la prevalencia de enfermedades gastrointestinales.</div><div><br /></div>
