A recent study has found that nine times more germs breed on the steering wheel of a car than on a public toilet seat.
The research found that while 80 bacteria prowl on each square inch of a toilet, almost 700 harmful bugs inhabit the interior of a car., reports the Daily Mail.
"While most of the bacteria were unlikely to cause health problems, some cars were found to play host to a number of potentially harmful bacterial species," the Daily Mail quoted Dr Ron Cutler, Director of Biomedical Science at Queen Mary University, London, as saying.
"A car is the perfect place for germs to breed, especially if you eat in it and leave litter or uneaten food around. To avoid potential health risks it would be wise to regularly clean your car inside and out," Cutler added.
Scientists also said the car boot is the filthiest area, with 1,000 bacteria for every one and half square inch.
The study has revealed that Bacillus Cereus, a bug found in rice, pasta, potatoes and pies, and which can cause food poisoning, is the most commonly found in cars.
Another bud arthrobacter, found in soil and human skin also features in the list.
