MILE-HIGH HEALTH RISKS
6 Places Germs Breed in a Plane
Flu season is in full swing, so it's more important than ever to protect yourself against illness. We dug deep to identify the major germ zones on planes (and tips to avoid them). No, you're not likely to contract meningitis, but better safe than sorry, right?
GERM ZONE: Water
FOR: E. coli, a common culprit behind stomach cramps
Your plane reaches 30,000 feet, the fasten-seat-belt sign switches off, and the flight attendant comes by to take your drink order: Coffee or tea? Ice water? They seem like innocent offers—until you consider that airplane water has been under review by the EPA for traces of E. coli for six years. A random sampling of 327 unnamed domestic and international aircraft caused a stir in 2004 when some water samples tested positive for E. coli, one strain of which is the leading cause of food poisoning in the U.S. Coffee and tea are brewed on board with such water and don't typically reach hot enough temperatures to kill E. coli. When bottled water runs out, some planes have been known to fill fliers' glasses from the tank. One British Airways crew member confessed to the London-based Times that, in those cases, the crew first has to wait for any cloudy "floating stuff" to settle out. And onboard tanks are small to limit their weight, so planes sometimes refill at foreign airports, where water standards can be questionable. The encouraging news is that water quality and control are improving: From 2005 to 2008, only 3.6 percent of samples tested positive for coliform bacteria, of which only a small fraction tested positive for E. coli. And in October 2011, the EPA's Aircraft Drinking Water Rule, with more standardized, stringent disinfection and inspection regulations, will go into effect.
TIP: Once you clear the security checkpoint, purchase a bottle of water to bring on board. When the flight attendant comes to take your order, stick to soda, juice, and other prepackaged liquids, minus the ice. While ice cubes are usually supplied by an outside vendor, some large planes may have their own ice-making capabilities—reliant on tank water.
GERM ZONE: Seat Pocket
FOR: Cold and influenza A, B, and C viruses
There's a familiar routine to settling in on a plane: Store your luggage in the overhead bin and deposit any personal items you want to be readily available in your seat pocket. But reaching into that pocket is akin to putting your hand in someone else's purse and rummaging among their used tissues and gum wrappers. Toenail clippings and mushy old French fries are even nastier surprises that have been found in seat pockets. Consider that cold and influenza viruses can survive for hours on fabric and tissues, and even longer (up to 48 hours) on nonporous surfaces like plastic and metal—and you realize that you might pick up more than that glossy flight magazine when you reach inside.
TIP: Bring a small, easily accessible carry-on bag so that you can avoid stashing things in the seat pocket. If you must use it, keep magazines and other items within a plastic bag for protection.
GERM ZONE: Tray Table
FOR: MRSA, a deadly superbug
Flight attendants have witnessed many repulsive misuses of the tray table, from parents changing dirty diapers to kids sticking their boogers underneath. Research confirms that the handy tray table is a petri dish for all kinds of health hazards, including the superbug Methicillin-resistant Staphylococcus Aureus (MRSA), which is often fatal once contracted. It kills an estimated 20,000 Americans annually. In 2007, University of Arizona researcher Jonathan Sexton tested tray tables from three major airliners, and an alarming 60 percent tested positive for the superbug. That's quite a revelation considering only 11 percent of his samples from the New York subway found traces of the bug.
TIP: Bring disinfectant wipes to clean off your tray table before and after use, and never eat directly off the surface. CDC guidelines tell you what to look for in a disinfectant and recommend checking a product's label to see if MRSA is on the list of bacteria it kills; Lysol disinfecting wipes is one reliable choice. And be sure to protect any cuts with Band-Aids—the most common way of contracting an MRSA infection is through open skin.
GERM ZONE: Airplane Meal
FOR: Listeria, a microbe known to cause gastrointestinal illness and meningitis
In-flight meals have long had a bad reputation for consisting of bland, barely identifiable dishes. Then, in 2009, the meals made headlines when FDA inspections of the Denver location of LSG Sky Chefs—the world's largest airplane caterer with clients including American Airlines, Delta, and United—found the kitchens crawling with roaches too numerous to count and employees handling the food with bare hands or unwashed gloves. Test samples from the food preparation area also found traces of Listeria monocytogenes, which can cause gastrointestinal illness and meningitis, as well as cervical infection in pregnant women. Your likelihood of contracting illness from the microbe is very low, though it should be noted that one fifth of the 2,500 annual cases are fatal. LSG Sky Chefs, to its credit, responded accordingly after the news broke and passed the FDA's follow-up inspection in January 2010.
TIP: It sounds like LSG has cleaned up its act, but you'll never really know where your meal has been. If you're concerned, eat beforehand and bring your own snacks onto the plane.
