Cars have 283 bacteria per cm

A study by Aston University shows drivers with pets and children are more likely to have high levels of bacteria riding along with them.

The most populated place with 356 germs identified per cm2 was the gear stick.

In one case a car had over 850 bacteria present per cm2, while bacterial traces of excrement were found in the boot of the car, in the same spot as weekly food shopping was regularly placed.

Dr Anthony Hilton, Aston University director of biology & biomedical science, said: "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.
