Go for a bracing winter stroll in a major US city and you will be inhaling more than vehicle fumes. A new study has demonstrated for the first time that during winter most of the airborne bacteria in three large Midwestern cities come from dog faeces. Noah Fierer at the University of Colorado, Boulder, found the high proportions of airborne dog faecal bacteria after analysing samples of winter air from Cleveland, Detroit and Chicago.
