The Dirtiest Areas Of Your Kitchen
A new study conducted by Currys PC World in collaboration with lab technician expert Dr. Jonathan Hughes analysed Brits’ kitchens revealing The dirtiest areas of our kitchens, highlighting the most founded bacteria and tips on how to get rid of them.

The top three germiest areas are:
Sponge – This is the dirtiest item in the kitchen with 35% of all the Faecal Streptococci colonies founded in the sponge you use to clean your dishes!
Sink – 100% of the sinks we analysed were positive for P. aeruginosa and 25% were positive for Faecal Streptococci which is more than the amount found in the bathroom sink.
Fridge – The place where we keep our delicious food also tested positive for germs and bacteria. 88% of fridge were positive for P. aeruginosa and 25% were positive for Faecal Streptococci.
Your Kitchen Sponge is germier than your floor
Sponges harbour the most germs in your kitchen
100% of sinks tested positive for Pseudomonas aeruginosa (P. aeruginosa)
The average sink is only cleaned every 25 days
The kitchen is often dubbed the ‘heart of the home’. It’s also where groceries enter the house, food is prepared and all sorts of items are stored. Now more than ever, people are at home and making cleaning a priority in their lives
The sponge, sink and floor are the germiest areas in your kitchen - It turns out, some of the items that are most vital to the cleaning process harbour the most germs. In fact, 100% of sinks tested positive for P. aeruginosa and 25% for FS, whereas 88% of sponges had P. aeruginosa, 25% had FS and 12% had E. coli. Why is this? Bacteria can thrive on damp surfaces, and due to the nature and purpose of your kitchen sink and sponge, bacteria transferred from hands, plates and other objects can linger in the moisture. Properly drying cloths and surfaces can reduce bacterial population.
The ‘five-second rule’ is a lie. 100% of floors tested had traces of aeruginosa and 12% of FS.
Sinks had a total concentration of 24,000 f aeruginosa and 3,280 of FS.
The average tea towel is only cleaned every two-and-a-half weeks, the sink every 25 days and the sponge every 15 days.
The average floor is only cleaned every five weeks.
37% of Brits do not clean their oven handle.
Kitchens are cleaner than expected. In fact, there were no traces of Salmonella found in any of the kitchens tested.
Lab technician at the University of Lincoln, Dr. Jonathan Hughes states that:
“As damp environments provide excellent conditions for bacterial growth, you should ring out and dry cloths, towels and sponges between uses.
You should also ensure that you regularly disinfect and wash reusable cloths or towels, or switch to new ones if using disposable cloths or sponges.”
Aeruginosa is definitely the head of the household, as we found traces of it on 100% of sinks and floors, and 88% of sponges, countertops and fridge shelves. This pathogen is found in soil and vegetation, and enters your kitchen on unwashed vegetables. It is known to cause symptoms such as skin irritation, abbesses and wounds.
In second place for the most prevalent germ in the kitchen, is Faecal streptococci (FS). This pathogen was found on 62% of the items we swabbed, including the sponge, sink, floor, countertop and the oven handle. It is found in the intestines of humans and animals, and detecting it in our test means there is a strong indication of faecal matter contamination. Such contamination can lead to symptoms of food poisoning such as, vomiting, diarrhoea and nausea.

You, your kitchen and your home are teeming with bacteria. Most of them are harmless, and some of them play an important role in promoting and mainlining good levels of health. However, some of them in high quantities can lead to particularly unpleasant symptoms, including severe food poisoning.
Dr. Hughes advises:
“The surface levels of bacteria in a normal kitchen are usually well below the levels required for infection of healthy individuals and so are unlikely to lead to illness – unless coupled with a pre-existing health complaint or if the person infected is immunocompromised.”
There was no detection of Salmonella, cereus or Staphylococcus aureus in any of the kitchens tested.
Your oven handle is the cleanest area in the kitchen, with 50% returning negative results of all pathogens tested. Among the remaining 50%, all tested positive for traces of aeruginosa and 12% tested positive for FS.
If you want to get rid of the bacteria in your house, the easiest way to keep you and your family safe is to have a thorough cleaning routine. For example, the average fridge is only cleaned every four-months-and-two-weeks, which could be why an astonishing 88% of fridges had detections of P. aeruginosa.Similarly, the average sink is cleaned every 25 days, which may be why it ranked second germiest place in the kitchen.
Dr. Hughes recommends that:
“following basic kitchen hygiene rules coupled with correct food preparation methods will reduce the risk of food poisoning. These rules can be grouped into four Cs: cleaning, cooking, chilling and cross-contamination.”
Cleaners are key: the kitchen that had the least amount of bacterial detections (five detections across eight areas, out of a maximum of 48) employed a cleaner to work regularly.
Retired couples that cleaned daily also had five detections of bacteria across eight areas.
