Rubber ducks and crocodiles have always been popular bathtime companions. An Eawag study has now revealed the “dark side” of flexible plastic bath toys. Diverse microbial growth is promoted not only by the plastic materials but by bath users themselves.
Warm, humid bathrooms provide ideal conditions for the formation of bacterial and fungal biofilms – for example, on shower curtains or behind cabinets. This applies in particular to rubber ducks and other bath toys. Dense growths of bacteria and fungi are found on the inner surface of these flexible toys, and a murky liquid will often be released when they
