In the United Kingdom, force-feeding was used against hunger-striking suffragettes, until the Cat and Mouse Act of 1913. Rubber tubes were inserted through the mouth (only occasionally through the nose) and into the stomach, and food poured down; the suffragettes were held down by force while the instruments invaded their bodies, an experience which has been likened to rape. In a smuggled letter, suffragette Sylvia Pankhurst described how the warders held her down and forced her mouth open with a steel gag. Her gums bled, and she vomited most of the liquid up afterwards.
Under United States jurisdiction, force-feeding is frequently used in the sui generis U.S. military prison in Guantanamo Bay, prompting in March 2006 an open letter by 250 doctors from seven Western countries in the medical journal The Lancet, warning that, in their opinion, the participation of any doctor is contrary to the rules of the World Medical Association. Retired Major General Paul E. Vallely visited Guantanamo and reported on the process of force-feeding:
In December 6, 2006, the UN War Crimes Tribunal at The Hague approved the use of force-feeding of Serbian politician Vojislav Šešelj. They decided it was not "torture, inhuman or degrading treatment if there is a medical necessity to do so...and if the manner in which the detainee is force-fed is not inhuman or degrading".
Force-feeding of humans was a common practice in the USSR. A brief, first-person account of a force-feeding session given by Vladimir Bukovsky describes the procedure in detail: "The feeding pipe was thick, thicker than my nostril, and would not go in. Blood came gushing out of my nose and tears down my cheeks, but they kept pushing until the cartilages cracked. I guess I would have screamed if I could, but I could not with the pipe in my throat. I could breathe neither in nor out at first; I wheezed like a drowning man — my lungs felt ready to burst. The doctor also seemed ready to burst into tears, but she kept shoving the pipe farther and farther down. Only when it reached my stomach could I resume breathing, carefully. Then she poured some slop through a funnel into the pipe that would choke me if it came back up. They held me down for another half-hour so that the liquid was absorbed by my stomach and could not be vomited back, and then began to pull the pipe out bit by bit.
Force-feeding of pernicious substances may be used as a form of torture and/or physical punishment. While in prison in northern Bosnia in 1996, some Serbian prisoners have described being forced to eat paper and soap
Sometimes it has been alleged that prisoners are forced to eat foods forbidden by their religion. The Washington Post has reported that Muslim prisoners in Abu Ghraib prison under the U.S.-led coalition described in sworn statements having been forced to eat pork and drink alcohol, both of which are strictly forbidden in Islam. Other prisoners described being forced to eat from toilets.
There are also cases in which force-feeding of harmful substances has been used by parents as a form of child abuse.
Force-feeding is also known as gavage, from a French word meaning "to gorge". This term specifically refers to force-feeding of ducks or geese in order to fatten their livers in the production of foie gras.
Force-feeding of birds is practiced mostly on geese or male Moulard ducks, a Muscovy/Pekin hybrid. Preparation for gavage usually begins 4–5 months before slaughter. For geese, after an initial free-range period and treatment to assist in esophagus dilation (eating grass, for example), the force-feeding commences. Gavage is performed 2–4 times a day for 2–5 weeks, depending on the size of the fowl, using a funnel attached to a slim metal or plastic feeding tube inserted into the bird's throat to deposit the food into the bird's crop (the storage area in the esophagus). A grain mash, usually maize mixed with fats and vitamin supplements, is the feed of choice. Waterfowl are suited to the tube method due to a non-existent gag reflex and extremely flexible esophagi, unlike other fowl such as chickens. These migratory waterfowl are also said to be ideal for gavage because of their natural ability to gain large amounts of weight in short periods of time before cold seasons. For this reason, gavage is usually a "finishing" stage before the bird is set for slaughter, for if left to its own devices after finishing, the bird will quickly return to its normal weight. The result of this practice is a severely enlarged, especially fatty liver, which — especially if exaggerated — results in the liver disease hepatic lipidosis. The liver may swell up to 12 times its normal size (up to three pounds). While the livers are the coveted portions of these birds, the fatty flesh of geese and ducks, traditionally used to make confit as well as their feathers find a market.
