British slaughter-house reformers campaigned to abolish private urban slaughter-houses and establish public abattoirs in the nineteenth century. Abolition of London's private slaughter-houses was motivated by the congestion created by livestock in city streets, the nuisance of slaughter-house refuse in residential neighbourhoods and public health concerns about diseased meat in the food supply. The butchers successfully defended their private slaughter-houses, illustrating the persistence of the craftsman's workshop and the importance of laissez-faire sentiments in opposition to municipalization in Victorian London.
