Kitchen Sponge Has 200,000 More Germs Than Toilet Seat and Could Even Lead to Paralysis
It may come as a surprise to the houseproud and ‘clean freaks’ among us but the kitchen sponge is one of the dirtiest places in the home – 200,000 times dirtier than a toilet seat.
And it is not just harmless bacteria lurking on your cleaning cloths and utensils.
Experts have linked germs found on sponges, cloths and chopping boards with a bacteria which can cause paralysis.
A new study has found there are around 10million bacteria per square inch of a kitchen sponge and a million per square inch on a dish cloth.
And you would be better off chopping your vegetables on a toilet seat than on a chopping board when it comes to germs, scientists have claimed.
Dr Charles Gerba, professor of microbiology at the University of Arizona, leads studies on how diseases are transferred through the environment.
His work involves swabbing household items and measuring the type and growth of bacteria.
He explained that the toilet seat is one of the cleanest things you’ll run across in terms of micro-organisms.
But he said we should be more worried about other household items, such as sponges, dish cloths, and reusable shopping bags.
Professor Hugh Pennington, one of Britain’s leading microbiologists, agreed the kitchen and in particular the sponge was among the dirtiest places in the home.
He said’It would be fine to use the sponge to wash up with, wiping food off the plates in hot water, but never, never use a sponge to wipe a plate clean.
‘There is a science to this sort of thing, and it’s not rocket science. There is a certain amount of common sense.’
Prof Pennington said one of the biggest targets for the Health Protection Agency was a bacteria called campylobacter – which can cause paralysis and is commonly found on kitchen sponges.
He said: ‘It is naturally occurring and comes from poultry. It can cause something called Guillain-Barre syndrome.It doesn’t affect your thinking or feeling, but it can spread to the peripheral nerves around the brain and effect movement. People can be effectively locked in.In the majority of cases, people will get better, but recovery can take weeks, months or years. ”
‘Always the dirtiest thing by far is the kitchen sponge,’ adds John Oxford, professor of virology at the University of London and chair of the Hygiene Council – the body that compares hygiene standards across the world.
In its latest study the council examines samples from homes in nine different countries, and finds that 21 % of ‘clean’ kitchen cloths actually have high levels of contamination.
The study identifies faecal bacteria in other places around the home, and this varies from one country to another.
According to the study Saudi Arabia has the dirtiest fridges, with 95 % of the fridges in the study failing the bacteriology test for E.coli.
In South Africa, the dirtiest item is the bath seal, with almost two-thirds with concerning levels of E.coli and 40per cent for mould.
How to Stop the Spread?
- The Hygiene Council advises all cloths, sponges and towels should be washed above 60C to kill germs or they should be disinfected regularly.
- An alternative would be to use disposable antibacterial wipes to discourage the spread of bacteria.
- Clean and disinfect the kitchen work surfaces and chopping boards with antibacterial sprays and wipes.
- As hands are the main route of transmission of germs during food preparation try not to touch items in the kitchen with dirty hands.
- Thorough hand washing with soap and water at key times during food preparation is essential to help prevent foodborne illness at home.
- Good home hygiene habits are essential and regular cleaning and ‘targeted disinfection’ of all surfaces that are regularly touched such as door handles, taps, switches and bin lids can help to reduce the spread of germs around the home.
- Some experts recommend microwaving dish cloths and sponges to kill germs instantly.
