    NSF International, a global public health and safety organisation, found that your kitchen is home to the most germ-ridden items in your house. Dish sponges and the kitchen sink were the top two dirtiest items found in the home. Scientists from the organisation tested 30 surfaces in 22 homes to measure levels of yeast, mould, salmonella, E.Coli and staph germs to find the top 10 dirtiest household items.

    It might shock you to learn that the toilet seat didn’t even make it onto the list. However, a bathroom item crept in as the third most germ-ridden object in the house – a toothbrush holder.

    If you didn’t already feel queasy at the idea of your kitchen sink holding more germs than your toilet. I’m sure you’re cringing at the idea of your toothbrush sitting in a bacteria ridden container.

    ‘While people may think areas such as the toilet seat are the dirtiest, it tends to be high-touch surfaces such as light switches and TV remotes,’ Karen Holeyman, Dyson Senior Research Scientist told

    ‘Food preparation surfaces such as chopping boards can harbour the most bacterial contamination, ‘ Karen adds. Chopping boards scraped in as the 10th dirtiest household item, after kitchen counters and stove knobs. Everyday items that live in the Kitchen took up 6 spaces in the top 10 list, making it the dirtiest room in the home.

    ‘Household dust can also be a concern as it may contain allergens such as dust mile, faeces, pollen and bacteria,’ Karen explains.
