The bottom of your bag is teeming with tens of thousands of bacteria per square centimetre, Gerba’s research shows. Germs climb aboard when you set your bag on the floor, so keep it on your shoulder or lap – and opt for leather bags, which are easy to disinfect with a weekly wipe.
Car consoles in warm climates are home to bacteria, while those in cold areas are prone to mould, Gerba says. Use antibacterial wipes to clean your dashboard, radio, indicator lever and headlight switch.
Water misters in the supermarket make vegetables and fruit look pretty, but the spouts can be filled with bacteria, which then get deposited on your dinner. So be sure to scrub produce under cold water, then pat it dry before putting it away in your fridge.
