Can coffee machines and kettles spread toxic spores?

Conclusion This laboratory study suggests that under humid conditions, indoor surfaces like wallpaper may be colonised by fungi that produce toxic particles – some of which may be small enough to be inhaled. But it's important that these findings aren't taken too far out of context at this stage. The study was carried out in highly experimental circumstances where both temperature and humidity were optimised for maximal fungal growth. We can't know for sure that these circumstances would be typical of indoor environments, even bathrooms or kitchens, if they're well ventilated. The UK media has applied these findings specifically to coffee machines, kettles and showers, but even though these appliances produce steam, it would be wrong to single them out as they haven't even been tested.  And the possible effects on human health also weren't tested in this study. The researchers found fungi can produce mycotoxins tiny enough to be inhaled. But we don't know whether the concentration of toxic particles and air speeds in homes would mean people breathe in enough particles to potentially harm their health. Fungal infections usually only pose a significant threat to the health of people with weakened immune systems or pre-existing lung conditions, such as cystic fibrosis. As the researchers rightly say, these findings need further testing. They don't have implications for how we use household appliances at the moment.
