According to a new paper published in British Mycological Society journal Fungal Biology, researchers at Oxford discovered that a potentially pathogenic fungus can grow in the extreme conditions present in common household appliances.
The study focused on the occurrence of potentially harmful fungi growing in dishwashers, over a sample of private homes from 101 cities on six continents. Of the dishwashers studied, 62 percent contained fungi on the rubber band in the door. More than half of those housed black yeasts that are associated with human disease.
Infections from exophiala dermatitidis, one of the fungi found in the study, can be fatal to even healthy humans. Researchers determined this evolution in fungal tolerance to environmental extremes could pose a significant health risk in the future.
