Kitchen Sponges: Cleaning Tool or Germ Dispenser?
By the Water Quality & Health Council

The notorious kitchen sponge—that germ-ridden object found in many households—is at the center of a new controversy about controlling the spread of infections in the home. Several years ago we reported a University of Florida research team found microwaving spongevery wet sponges for two minutes at high power killed or inactivated over 99 percent of all the living pathogens in sponges and cleaning pads that had been soaked in a “witch’s brew of germs.” Easy and convenient, right? Think again: A team of German researchers using genetic techniques to characterize sponge microbes says that neither boiling nor microwaving sponges may be particularly effective in the long run. Careful testing of alternative sponge treatments is needed, but in the meantime, the researchers recommend the best course may be ditching your kitchen sponge once per week for a new one.

Preparing for the Next Flood and its Aftermath
By Fred Reiff, P.E.

If you live in a flood-prone area, are you prepared for the next deluge? According to the National Oceanic and Atmospheric Administration (NOAA), fast moving water that reaches just over your ankles can knock you off your feet. And don’t try to drive through it. Driving on flooded roads is the floodmost common thunderstorm-related hazard that can kill you, according to NOAA. It is especially difficult to recognize flood danger in darkness or other conditions of poor visibility. As the National Weather Service urges, if you come to a flooded portion of roadway, “Turn Around Don’t Drown®”.

Head for the Hills

If it is necessary to evacuate your home, head for higher ground at a pre-designated meeting place known to your family. Pet owners should have an emergency plan for their pets that includes shelter, food and water. If possible, turn off electrical power, gas and water supplies … READ MORE >>


Sepsis: A New Global Health Priority
By Ralph Morris, M.D., M.P.H.

“Sepsis,” according to the Centers for Disease Control and Prevention (CDC), is “a complication caused by the body’s overwhelming and life-threatening response to infection, which can lead to tissue damage, organ failure, and death.” More commonly known as “blood poisoning,” sepsis strikes “with equal ferocity in resource-poor areas and in the developed world,” according to Dr. Konrad Reinhart, Chairman of the Global Sepsis Alliance. Sepsis is now front and center for the world health community: At a May 2017 World Health Assembly1, sepsis was designated a new global health priority and a resolution was adopted to improve its prevention, diagnosis and management.

Although reliable data are unavailable, globally there are an estimated 31 million cases and some six million deaths from sepsis annually.2 Most of those deaths are preventable, however, with early detection and timely treatment with antibiotics. According to one study involving over 2,000 septic … READ MORE >>


Climbing the Rungs of the Safe Water and Sanitation Service Ladders

The humble ladder can be a symbol of progress toward lofty goals. The lyrics of Bob Dylan’s “Forever Young,” for example, include a moving wish for the singer’s newborn son: “May you build a ladder to the stars and climb on every rung…” Symbolic ladders are also used by the Joint Monitoring Program of the World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF) to communicate progress toward the goal of universal safe drinking water and sanitation.

In “UN-speak,” that ambitious goal is Post-2015 Sustainable Development Goal #6, which includes specific targets and indicators that will help track progress toward a world in which waterborne illnesses are rare and sanitation is safely managed.

The reusable water bottle is one of those “grab and go” items that travel with many of us on a daily basis. The filled water bottle provides a handy means of hydrating on the spot. As we’ve noted, many water fountains now conveniently include water bottle-filling features. There’s just one caveat to deriving the maximum health benefit from reusable water bottles: They should be thoroughly cleaned and sanitized on a regular basis to avoid contamination.

Germs Love Moist Environments

Germs thrive in moist environments such as parts of the cap and interior of your water bottle. As Dr. Charles Gerba of the University of Arizona notes, if you use your fingers to open and close the water bottle cap, there is a good chance that bacteria will be introduced into the cap, where moisture will support its … READ MORE >>
