\n

Las esponjas de cocina son un perfecto caldo de cultivo para bacterias.<\/p>\n<\/div>\n

\n

Cient\u00edficos en Alemania secuenciaron el ADN de microorganismos hallados en 14 esponjas de cocina y hallaron bacterias como\u00a0Moraxella osloensis<\/i>, que puede causar infecciones en personas con un sistema inmunol\u00f3gico d\u00e9bil.<\/p>\n<\/div>\n

\n

La misma bacteria es responsable del mal olor en la ropa sucia y podr\u00eda explicar el aroma nada agradable de las esponjas de cocina usadas una y otra vez.<\/p>\n<\/div>\n

\n

“Nuestro trabajo demuestra que las esponjas de cocina albergan una diversidad de bacterias mucho mayor de lo que se pensaba”, concluyeron Massimiliano Cardinale, del Instituto de Microbiolog\u00eda Aplicada de la Universidad Justus Liebeg en Giessen, y colegas de otros centros en Alemania.<\/p>\n<\/div>\n

\n

Y un serio problema identificado por los investigadores es que lavar las esponjas con agua y jab\u00f3n aumenta la concentraci\u00f3n de algunas bacterias, seg\u00fan el estudio.<\/p>\n<\/div>\n

\n

Resistentes<\/h2>\n<\/div>\n
\n

Cuando los investigadores observaron las esponjas con microscopios descubrieron que un cent\u00edmetro c\u00fabico de esponja puede albergar una densidad de bacterias similar a la que se encuentra en las heces.<\/p>\n<\/div>\n

\n

Pero hervir las esponjas o ponerlas en el microondas no las desinfecta, de acuerdo con el estudio.<\/p>\n<\/div>\n

\n

Y las esponjas lavadas regularmente con agua y jab\u00f3n o detergente tienen un porcentaje mayor de bacterias perjudiciales que las que jam\u00e1s hab\u00edan sido limpiadas.<\/p>\n<\/div>\n

\n

\u00bfC\u00f3mo puede ser?<\/p>\n<\/div>\n

\n

Una posible explicaci\u00f3n es que las bacterias m\u00e1s perjudiciales son tambi\u00e9n m\u00e1s resistentes y r\u00e1pidamente recolonizan las \u00e1reas abandonadas por otros microbios m\u00e1s susceptibles a los detergentes.<\/p>\n<\/div>\n

\n

Soluci\u00f3n de lej\u00eda<\/h2>\n<\/div>\n
\n

Algunos expertos recomiendan lavar las esponjas con una soluci\u00f3n de lej\u00eda.<\/p>\n<\/div>\n

\n

Philip Tierno, profesor del departamento de Microbiolog\u00eda y Patolog\u00eda del Centro M\u00e9dico Langone de la Universidad de Nueva York y autor del libro “La vida secreta de los g\u00e9rmenes”, advierte que si no limpiamos adecuadamente las esponjas simplemente cubrimos los platos al lavarlos con una “capa de g\u00e9rmenes”.<\/p>\n<\/div>\n

Pie de foto, <\/span>El estudio recomienda reemplazar las esponjas regularmente, “por ejemplo, cada semana”.<\/span><\/span><\/figcaption><\/figure>\n
\n

La mejor opci\u00f3n, seg\u00fan se\u00f1al\u00f3 Tierno a medios en Estados Unidos, es preparar una soluci\u00f3n mezclando nueve partes de agua y una de lej\u00eda.<\/p>\n<\/div>\n

\n

Siempre usando guantes, se debe vertir luego la mezcla sobre la esponja y dejarla en esta soluci\u00f3n entre 10 y 30 segundos.<\/p>\n<\/div>\n

\n

Tierno sugiere guardar un recipiente con la mezcla y tenerlo a mano para limpiar la esponja luego de casa uso.<\/p>\n<\/div>\n

\n

Tras sumergirla durante el tiempo adecuado en la mezcla, simplemente se debe apretar la esponja para escurrir el l\u00edquido y dejarla secar.<\/p>\n<\/div>\n

\n

Cada semana<\/h2>\n<\/div>\n
\n

Si lavar la esponja en lej\u00eda luego de cada uso te parece algo engorroso, los investigadores de Alemania tienen otra soluci\u00f3n mucho m\u00e1s simple.<\/p>\n<\/div>\n

\n

Los m\u00e9todos m\u00e1s comunes para limpiar esponjas, como lavarlas con detergente, “no parecen ser suficientes para reducir la carga de bacterias”, se\u00f1ala el estudio.<\/p>\n<\/div>\n

\n

“Por ello recomendamos reemplazarlas con frecuencia, por ejemplo, cada semana”.<\/p>\n<\/div>\n

\n

Y no olvides que, seg\u00fan recuerda Tierno, “una esponja que huele mal es una esponja llena de g\u00e9rmenes”.<\/p>\n<\/div>\n

\n

El estudio de los investigadores alemanes fue publicado en la revista cient\u00edfica online\u00a0Scientific Reports<\/i>.<\/p>\n<\/div>\n
