Research shows polyurethane kitchen sponge helps keep E. coli at bay

* Gerba.jpgFXI, the producer of innovative foam products, reports that a groundbreaking study by Charles P. Gerba, Ph.D., a renowned professor of microbiology and environmental sciences at the University of Arizona, reveals that using a kitchen sponge made of polyurethane foam significantly reduces the spread of E. coli, decreasing the risk of infection by up to 90%, when compared to a traditional cellulose sponge.

According to the study, levels of fecal bacterium E. coli were always 99.9% less in polyurethane sponges than in cellulose sponges after use in households for one month.

The study, funded by FXI, was published in a peer-reviewed article by Food Protection Trends. It found several advantages to using polyurethane sponges over cellulose sponges, which Dr. Gerba's research previously found to be 200,000 times dirtier than a toilet seat.

According to Dr. Gerba's latest study, a cellulose sponge becomes highly contaminated with millions of bacteria in just two to three days after initial use. Polyurethane sponges are significantly more resistant to contamination and showed 100 times less E. coli bacteria than cellulose sponges after 28 days on average.

"Cleaning with a cellulose sponge can cause fecal matter to spread around kitchen surfaces as well as your hands," says Dr. Gerba. "Most kitchens cleaned using cellulose sponges wouldn't pass a restaurant inspection. Polyurethane sponges always have fewer bacteria than cellulose sponges."

Dave Minning, FXI's executive vice president & chief commercial officer, adds: "We have always believed that sponges made from our polyurethane foam provide for an outstanding cleaning tool, but are pleased to see that there is now scientific evidence that they also offer significant health benefits."
