Thread: Got a Hot Tub? Use an Escalator? Swim in a Pool? Take a Shower?

    Scientist takes aim at microbial scum - Our bodies do battle with armies of everyday germs The Associated Press
    That soap scum that forms on the shower curtain? ItÂ’s really a biofilm loaded with more than a billion bacteria per cubic inch.
    The moving belt on an escalator? When you put your hand there, youÂ’re dipping into a puddle of bacteria left by all those who went before.
    How about the potting soil for your petunias? ItÂ’s the happy home of a pathogen called Microbial Avian Complex, a potentially troublesome bug.
    Then thereÂ’s the sponge you use to rinse dishes at the sink. Yep, loaded with thriving bacteria.
    If this makes you want to go relax in a hot tub, think again. The air wafting from the hot water is probably loaded with microbes, some of them able to give you a hacking cough.
    Living in the microbial world
    ItÂ’s a microbial world, says Norman P. Pace, a researcher at the University of Colorado at Boulder. Virtually everything you touch is coated with the little critters. You couldnÂ’t escape them if you wanted to because your skin is covered with about 100 million bacteria, says Pace.
    Yet, science knows very little about environmental microbes, how they live, reproduce and thrive in the natural world. Most of what is known comes from germs cultured and studied in the lab.
    “We live in a microbial world and I find it appalling that this is ignored by science,” Pace said Saturday at the national meeting of the American Association for the Advancement of Science.
    He discovered the colonies of soap scum bacteria when, out of curiosity, he took a sample from his own shower curtain and examined it under a microscope.
    “I was amazed,” he said. Later studies of shower curtains from other homes found the same thing.
    “When you step into a shower, you are enmeshed in a bio-aerosol,” he said.
    Everyday health risks
    Most of the soap scum bacteria is harmless to the healthy. But for people with compromised immune systems, such as patients with AIDS or on chemotherapy or with open wounds, some of the germs can be deadly.
    Pace recommends that shower curtains be cleaned weekly.
    When he rides an escalator, Pace said he puts down only his knuckles because of the potential broth of bacteria that may be present.
    The kitchen sink sponge, he said, “is a spectacular source of bacteria.”
    In his own home, he regularly wrings out the sponge and lets it dry, breaking up the wet, warm bacteria paradise.
    Pace explored the microbial world of hot tubs after he was asked to investigate why some on the staff at a therapeutic swimming pool were developing “lifeguard lung,” a nagging cough that plagues pool workers.
    Studying 'lifeguard lung'
    He found that the air above a heated, indoor pool or above a hot tub is enriched with microbe by about 60 percent. Persistent exposure to the air caused the “lifeguard lung” in sensitive people. The same thing can happen around a hot tub.
    “These findings are a bit scary. The bottom line is people should be aware of the risk of swimming in indoor pools or sitting in indoor hot tubs,” Pace said.
    One hot tub and pool solution, he said, is to increase ventilation so the cloud of microbes is swept away. “Lifeguard lung” generally clears when the exposure is stopped.
    But, Pace said, “I wouldn’t get into a public hot tub, or even a private one for that matter.”
    No need for extremes
    Despite the scary image of bacteria everywhere, Pace said it’s not reasonable to go into a “Howard Hughes mode.” The late billionaire isolated himself and sterilized most things out of fear of germs.
    Among microbes there are good guys and bad guys. Many bacteria are beneficial, helping to keep the harmful ones in check. Antibiotics can kill both the useful germs and the bad ones. That gives an advantage to bacteria that are resistant to antibiotics, some of which can be harmful.
    Instead, Pace practices prudence.
    People should wash their hands frequently, clean off soap scum often, dry out the kitchen sponge and avoid excessive exposure to indoor pools and hot tubs, he said.
    Pace said there also needs to be more research about the life and times of microbes in the natural world so science can determine where there is a risk to human health and then develop solutions.

    Please note that that's an indoor pool and hot tub....

    I bet Norman doesn't park his boat in the channel.

    you know alcohol kills germs....... so my recommendation, drink heavily and often....

    They didn't even mention the channel....
    But I take offense to the Hot Tub comment...I keep my boat really clean!!
