, 1893 Until modern times, the slaughter of animals generally took place in a haphazard and unregulated manner in diverse places. Early maps of London show numerous
stockyards in the periphery of the city, where slaughter occurred in the open air or under cover such as
wet markets. A term for such open-air slaughterhouses was
shambles, and there are streets named "
The Shambles" in some English and Irish towns (e.g.,
Worcester,
York,
Bandon) which got their name from having been the site on which butchers killed and prepared animals for consumption.
Fishamble Street, Dublin, was formerly a
fish-shambles. Sheffield had 183 slaughterhouses in 1910, and it was estimated that there were 20,000 in England and Wales.
Reform movement The slaughterhouse emerged as a coherent institution in the 19th century. A combination of health and social concerns, exacerbated by the rapid
urbanisation experienced during the
Industrial Revolution, led
social reformers to call for the isolation, sequester and regulation of animal slaughter. As well as the concerns raised regarding hygiene and disease, there were also criticisms of the practice on the grounds that the effect that killing had, both on the butchers and the observers, "educate[d] the men in the practice of violence and cruelty, so that they seem to have no restraint on the use of it." An additional motivation for eliminating private slaughter was to impose a careful system of regulation for the "morally dangerous" task of putting animals to death. in 1855, before it was reconstructed As a result of this tension, meat markets within the city were closed and abattoirs built outside city limits. An early framework for the establishment of public slaughterhouses was put in place in Paris in 1810, under the reign of the
Emperor Napoleon. Five areas were set aside on the outskirts of the city and the feudal
privileges of the guilds were curtailed. As the meat requirements of the growing number of residents in London steadily expanded, the meat markets both within the city and beyond attracted increasing levels of public disapproval. Meat had been traded at
Smithfield Market as early as the 10th century. By 1726, it was regarded as "without question, the greatest in the world", by
Daniel Defoe. By the middle of the 19th century, in the course of a single year 220,000 head of cattle and 1,500,000 sheep would be "violently forced into an area of five acres, in the very heart of London, through its narrowest and most crowded thoroughfares". as well as the brutal treatment of the cattle. In 1843, the ''Farmer's Magazine'' published a petition signed by bankers, salesmen, aldermen, butchers and local residents against the expansion of the livestock market. The
Town Police Clauses Act 1847 created a licensing and registration system, though few slaughter houses were closed. An
Act of Parliament was eventually passed in 1852. Under its provisions, a new cattle-market was constructed in Copenhagen Fields,
Islington. The new
Metropolitan Cattle Market was also opened in 1855, and West Smithfield was left as waste ground for about a decade, until the construction of the new market began in the 1860s under the authority of the 1860 Metropolitan Meat and Poultry Market Act. The market was designed by
architect Sir
Horace Jones and was completed in 1868. A
cut and cover railway tunnel was constructed beneath the market to create a triangular junction with the railway between
Blackfriars and
King's Cross. This allowed animals to be transported into the slaughterhouse by train and the subsequent transfer of animal carcasses to the Cold Store building, or direct to the meat market via lifts. At the same time, the first large and centralized slaughterhouse in Paris was constructed in 1867 under the orders of
Napoleon III at the
Parc de la Villette and heavily influenced the subsequent development of the institution throughout Europe.
Regulation and expansion These slaughterhouses were regulated by law to ensure good standards of hygiene, the prevention of the spread of disease and the minimization of needless animal cruelty. The slaughterhouse had to be equipped with a specialized water supply system to effectively clean the operating area of blood and offal. Veterinary scientists, notably
George Fleming and John Gamgee, campaigned for stringent levels of inspection to ensure that
epizootics such as
rinderpest (a devastating outbreak of the disease covered all of Britain in 1865) would not be able to spread. By 1874, three meat inspectors were appointed for the London area, and the
Public Health Act 1875 required local authorities to provide central slaughterhouses (they were only given powers to close unsanitary slaughterhouses in 1890). Yet the appointment of slaughterhouse inspectors and the establishment of centralised abattoirs took place much earlier in the British colonies, such as the colonies of New South Wales and Victoria, and in Scotland where 80% of cattle were slaughtered in public abattoirs by 1930. In Victoria the
Melbourne Abattoirs Act 1850 (NSW) "confined the slaughtering of animals to prescribed public abattoirs, while at the same time prohibiting the killing of sheep, lamb, pigs or goats at any other place within the city limits". Animals were shipped alive to British ports from Ireland, from Europe and from the colonies and slaughtered in large abattoirs at the ports. Conditions were often very poor. Attempts were also made throughout the British Empire to reform the practice of slaughter itself, as the methods used came under increasing criticism for causing undue pain to the animals. The eminent physician,
Benjamin Ward Richardson, spent many years in developing more humane methods of slaughter. He brought into use no fewer than fourteen possible anesthetics for use in the slaughterhouse and even experimented with the use of electric current at the
Royal Polytechnic Institution. As early as 1853, he designed a lethal chamber that would gas animals to death relatively painlessly, and he founded the Model Abattoir Society in 1882 to investigate and campaign for humane methods of slaughter. The invention of
refrigeration and the expansion of transportation networks by sea and rail allowed for the safe exportation of meat around the world. Additionally, meat-packing millionaire
Philip Danforth Armour's invention of the "disassembly line" greatly increased the productivity and profit margin of the
meat packing industry: "according to some, animal slaughtering became the first
mass-production industry in the United States." This expansion has been accompanied by increased concern about the physical and mental conditions of the workers along with controversy over the ethical and environmental implications of slaughtering animals for meat. The development of slaughterhouses was linked with industrial expansion of by-products. By 1932 the British by-product industry was worth about £97 million a year, employing 310,000 people. The Aberdeen slaughterhouse sent hooves to Lancashire to make glue, intestines to Glasgow for sausages and hides to the Midland tanneries. In January 1940 the British government took over the 16,000 slaughterhouses and by 1942 there were only 779. ==Design==
