Germs Right at Home in American Houses

Americans Rank High for Hygiene Habits Despite Germy Kitchens, Bathrooms

Oct. 14, 2010 -- Many U.S. homes have disease-causing germs, but Americans rank among the highest in practicing good hygiene, a new study shows.

The 2010 study called Hygiene Home Truths conducted by the Hygiene Council says that even though the U.S. ranks high in hygiene practices, there is plenty of room for improvement, especially in bathrooms and kitchens.

The council sent germ- and mold-spore hunters armed with swabs into homes in the U.S., the United Kingdom, Germany, Canada, South Africa, Saudi Arabia, Malaysia, Australia, and India, looking for microscopic evidence of germs.

Homes of people who agreed to participate were swabbed for bacteria and mold.

U.S. Homes Cleaner Than Most

The study says that 89% of U.S. samples were satisfactory or spotless, but that we’re still not doing enough cleaning, leaving behind bacteria and mold that increase the risk of illness.

According to the study, the biggest hotspot for germs was found to be the bathtub seal between the tub and tile, 40% of which were rated unsatisfactory or heavily contaminated.

The council says this area is particularly worrisome, because kids, when being bathed, are often close enough to these areas to pick up bad bugs.

The kitchen towel was the second most heavily contaminated area swabbed by germ sleuths, with 15% ranking unsatisfactory or heavily contaminated.

The council says a growing concern in U.S. households is the presence of the bacteria staphylococcus aureus, commonly called staph, which was identified on 11% of computer keyboards or mouses.

This indicates that some homeowners aren’t washing their hands, or at least not properly.

Findings for Homes in the U.S.

Among other findings for U.S. homes:

  • People in 25% of households said they never cleaned the computer keyboard, and 23% said they cleaned it only once a week.
  • 80% of U.S. households said they cleaned refrigerators once a month.
  • 95% said they didn’t know that household mold can cause respiratory illnesses.
  • 85% of householders felt their homes were at least satisfactorily clean, if not spotless, possibly due to the fact that 55% of respondents said they have a cleaner or domestic help.
  • 100% of teapot or coffeepot handles in the U.S. were found to be satisfactory or spotless.
  • 5% of households flunked the council’s cleanliness test for computer keyboards and mouses. And 5% of refrigerator interiors in the U.S. failed the council’s cleanliness test.
