More than 60% of dishwashers contain potentially harmful fungi that can cause lung problems and skin infections Fungi thrive because of the warm, damp conditions These fungi can colonise the lungs and cause infections Particularly dangerous for people with poor immune systems such as those with diabetes or cystic fibrosis Dishwashers are a breeding ground for potentially harmful fungi because it thrives in warm and wet conditions Dishwashers are a breeding ground for potentially harmful fungi, new research has revealed. Researchers found that the warm, damp environment in dishwashers is ideal for the growth of fungi including Exophiala, Rhodotorula, and Candida parapsilosis - yeast-like species that can be harmful to people. The study, published in the journal Medical Mycology, saw dishwashers across the world tested for fungi and revealed that 62 per cent contain the species. If inhaled, these fungi can colonise the lungs and cause infections that can be difficult to treat. The researchers found that the rubber seals in dishwasher doors are a perfect breeding ground for fungi and that some types, such as Exophiala. They also discovered that some fungi are particularly likely to grow in dishwashers as they thrive in salty conditions, such as those created by dishwasher powder.
