Slaughterhouse
In livestock agriculture and the meat industry, a slaughterhouse, also called an abattoir ('æb@twɑr), is a facility where livestock animals are slaughtered to provide food. Slaughterhouses supply meat, which then becomes the responsibility of a meat-packing facility. Slaughterhouses that produce meat that is not intended for human consumption are sometimes referred to as knacker's yards or knackeries. This is where animals are slaughtered that are not fit for human consumption or that can no longer work on a farm, such as retired work horses. Slaughtering animals on a large scale poses significant issues in terms of logistics, animal welfare, and the environment, and the process must meet public health requirements. Due to public aversion in different cultures, determining where to build slaughterhouses is also a matter of some consideration. Frequently, animal rights groups raise concerns about the methods of transport to and from slaughterhouses, preparation prior to slaughter, animal herding, and the killing itself. 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. 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.
