Could your tea towel give you food poisoning?
How hygienic is your tea towel?

Raise your hand if you wash your kitchen tea towel every day. Yep, we don’t either. But new research has found that your humble tea towel could be putting you and your family at risk of food poisoning. So, you might want to start popping yours in the wash a lot more often after reading this.

After analysing 100 tea towels, scientists at the University of Mauritius found alarmingly high amounts of bacteria, including E. coli, which causes everything from food poisoning to urinary tract infections.

The researchers supplied 100 tea towels to participants (36 were a mixture of cotton and nylon, 31 were pure cotton and 33 were pure nylon) and collected them after one month to analyse any bacteria present on them.

The results revealed bacterial growth in 49 per cent of the tea towels, with cotton tea towels having the highest bacterial levels of all three kinds.

The study identified two factors that led to increased bacterial growth: multipurpose use and family size. Tea towels that were used for a variety of tasks (such as for wiping bench tops, in addition to drying hands and dishes) had the highest levels of bacteria.

Likewise, the researchers found bacterial growth increased significantly in families with more people and particularly where children were present.

Now, before you get too worried, here’s some context:
The participants were asked questions about their lifestyle and family, including their tea towel use, diet and family size. However, they weren’t asked whether they had actually contracted food poisoning or other gastrointestinal illnesses during the one-month period.

The researchers also found that moist or ‘humid’ tea towels had significantly higher traces of particular types of bacteria, such as coliforms, which are a class of bacteria typically found in the digestive tract and faeces of animals (including humans). While most coliforms are harmless, rare strains do exist that can cause serious illness.

What does it all mean?
Overall, while the research sheds some light on the state of the humble kitchen tea towel, we needn’t be too concerned. Most of the bacteria found were of the enterococcus and pseudomonas species, which don’t typically cause food poisoning.

However, the research does give us some practical points to think about.

To limit your and your family’s exposure to bacteria, it’s best to wash your tea towel after every use. If this is impossible or unlikely, waiting until tea towels are dry will help, as dry tea towels have a lower bacteria load than damp ones.

Another tip is to use tea towels for single purpose and not for multiple tasks. You might consider colour coding your tea towels and using them for designated tasks; one for drying the dishes, another for drying hands, etc. This will also help to reduce the towel’s bacteria load.

Are you guilty of using your tea towel for days on end without washing it? And do you use it to wipe up the occasional spill on the floor?

    I use a tea towel ONCE and same with a dishcloth -- then they are into the wash -- I also have separate hand towels and they are changed every day or mare -- depends on how often I use it

    Use 'em till them turn green! Never poisoned anyone! We are in the age of "germophobia' where everything has to be sprayed with disinfectant till our immune system no longer can cope with the simplest illness. Let 'em eat dirt , I say.

    I agree (esp re germophobia & immune systems), jus gotta be sensible about it!
    Those clean freaks who clean everything like mop floors & wipe benches & vac & dust (oh & scrub bathroom, toilet & laundry etc) everyday need to get a life, the time wasted cleaning could be spent with friends, family or travelling & having fun!

    Such bravery will only rarely outlast Salmonella food poisoning.

    Wiping hands and dishes with same tea towel is a no no.

    I use a tea towel for getting hot things out of the microwave. Utensils and dishes air dry.

    I use lots of tissues to substitute for bread and butter plates.

    I don't use the tea towel to dry the dishes so they can carry as many microbes as they like.

    Under the impression that most people have dishwashers. Personally I just wash my dishes and leave them to dry on the rack. You can pick up germs anywhere.

    this ridiculous obsession with disinfectants and maniacal cleanliness got us all the allergies that this generation suffers from which we'd never heard of before.. and imagine what it does to the waterways all this detergent/bleach/disinfectant in mega quantities!
    i for one have never suffered any ill effects from a slightly over used towel! get a life folks!!

    I agree with those who say about the obsession with germs in the home. There is far too much worry about it and especially taking notice of the commercials selling there disinfectant products. Nevertheless one should use commonsense in regard to the use of tea towels. We have a slow combustion stove and keep the tea towels hanging on its door racks so they are dried constantly.
