Your Car is a Germ-Mobile

“People would be horrified at the thought of eating off their toilet seat,” says British researcher Anthony Hilton. “But few realize eating off their car dashboard is just as likely to make them sick.” Hilton was the leader of a new British study by Aston University in Birmingham which shows the typical vehicle harbors over 280 different bacteria per square centimeter. The study, conducted for a U.K. insurance company, showed some spots are nastier than others—the gearshift, for example, usually crawls with over 350 different varieties. The worst place is the trunk, where about 850 bacteria typically hitch a ride. Scientists even found evidence of excrement in one Germ-Mobile’s trunk, which is where many people put their grocery bags. They also found that cars used to transport kids and pets are the germiest. “Whilst most of the bacteria we’ve found are unlikely to cause serious health problems, some cars, particularly those which regularly carry children and animals, play host to potentially harmful germs,” Hilton said. And you may want to think twice before turning on the heater or air conditioner—when the fan comes on, it blows even more germs and fungi around the interior, probably because few people regularly replace the vehicle’s interior air filter. Most of the people whose vehicles were used for study owned up to being slobs with their cars, and half said they would never allow their homes to get in the condition their cars were in. .
