Controlling contagion? Watercress, regulation and the Hackney typhoid outbreak of 1903

Abstract The part played by the public health movement in controlling epidemics in urban areas has received considerable attention from historians, as has the regulation of the milk and meat industries that commenced in the late nineteenth century. However, comparatively little work has been carried out on health in a rural context – and the role played by the horticultural sector in the spread of contagious diseases has barely been covered. Yet, as this article shows, it was a sector that had the potential to produce potent contaminants. By examining histories of the production of one horticultural crop, watercress, it reveals how issues around the provision of a clean urban water supply and idealised imaginings of the countryside as a pure space, played a part in exacerbating the extent of outbreaks of typhoid in the industrial city. It also shows that there was governmental reluctance to regulate an industry that grew a staple product, even when growers themselves were keen for guidance.
