Bushmeat refers to meat from wildlife Hunting for human consumption, especially in parts of Africa, Asia, and South America. Bushmeat is commonly harvested through unregulated or subsistence hunting practices. Bushmeat often consists of prevalent small in an area, such as , , and , but can also refer to small and .
In a public health context, bushmeat is of concern due to its association with the transmission of Zoonosis diseases such as Ebola and HIV, as well as other emerging infectious diseases linked to the handling, butchering, and consumption of wild animals. Bushmeat represents a primary source of animal protein and a cash-earning commodity in poor and rural communities of humid tropical forest regions of the world.
The numbers of animals killed and traded as bushmeat in 1994 in West Africa and Central Africa were thought to be unsustainable. By 2005, commercial harvesting and trading of bushmeat was considered a threat to biodiversity. As of 2016, 301 terrestrial were threatened with extinction due to hunting for bushmeat including non-human primates, even-toed ungulates, , Diprotodontia, and occurring in developing countries.
Wildlife hunting for food is important for the livelihood security of and supply of dietary protein for poor people. It can be sustainable when carried out by traditional in large landscapes for their own consumption. Due to the extent of bushmeat hunting for wildlife trade in markets, the survival of those species that are large-bodied and reproduce slowly is threatened. The term bushmeat crisis was coined in 2007 and refers to this dual threat of depleting food resources and wildlife , both entailed by the bushmeat trade.
The volume of the bushmeat trade in West Africa and Central Africa was estimated at per year at the turn of the 21st century. In 2002, it was estimated that species weighing more than contribute of meat per year to the bushmeat extracted in the Congo Basin, based on 24 individuals. Species weighing less than were estimated to contribute , also based on 24 individuals. Bushmeat extraction in the Amazon rainforest was estimated to be much lower, at in the case of species weighing more than 10 kg and in the case of species weighing less than 10 kg, based on 3 individuals.
Based on these estimates, a total of bushmeat is extracted in the Congo Basin per year, ranging from in Equatorial Guinea to in the Democratic Republic of the Congo.
The 301 mammal species threatened by hunting for bushmeat comprise 126 primates, 65 even-toed ungulates, 27 bats, 26 diprotodont marsupials, 21 rodents, 12 carnivores and all pangolin species.
Primate species offered fresh and smoked in 2009 at a wildlife market by Liberia's Cavally River included chimpanzee ( Pan troglodytes), Diana monkey ( Cercopithecus diana), putty-nosed monkey ( C. nictitans), lesser spot-nosed monkey ( C. petaurista), Campbell's mona monkey ( C. campbelli), sooty mangabey ( Cercocebus atys), king colobus ( Colobus polykomos), olive colobus ( Procolobus verus), western red colobus ( P. badius). Duiker species constituted more than half of the total 723 animals offered.
In 2012, the bushmeat trade was surveyed in three villages in the Sassandra Department, Ivory Coast. During six months, nine restaurants received 376 mammals and eight reptiles, including dwarf crocodile ( Osteolaemus tetraspis), harnessed bushbuck ( Tragelaphus scriptus), Maxwell's duiker ( Philantomba maxwellii), bay duiker ( Cephalophus dorsalis), Campbell's mona monkey, lesser spot-nosed monkey, potto ( Perodicticus potto), tree pangolin ( Phataginus tricuspis), long-tailed pangolin ( P. tetradactyla), African brush-tailed porcupine ( Atherurus africanus), giant pouched rat ( Cricetomys gambianus), greater cane rat ( Thryonomys swinderianus), striped ground squirrel ( Xerus erythropus) and western tree hyrax ( Dendrohyrax dorsalis).
About 128,400 straw-coloured fruit bats ( Eidolon helvum) were estimated in 2011 to be traded as bushmeat every year in four cities in southern Ghana.
In 2006, it was estimated that about 1,437,458 animals are killed every year in the and Cameroon parts of the Cross-Sanaga-Bioko coastal forests, including about 43,880 Emin's pouched rats ( Cricetomys emini), 41,800 tree pangolins, 39,700 putty-nosed monkeys, 22,500 ( Cercopithecus mona), 3,500 ( C. erythrotis), 20,300 drills ( Mandrillus leucophaeus), 15,300 ( Civettictis civetta), 11,900 ( Crossarchus obscurus), more than 7,600 African palm civets ( Nandinia binotata), 26,760 ( Varanus niloticus) and 410 African forest elephants ( Loxodonta cyclotis).
Between 1983 and 2002, the Gabon populations of western gorilla ( Gorilla gorilla) and common chimpanzee ( Pan troglodytes) were estimated to have declined by 56%. This decline was primarily caused by the commercial hunting, which was facilitated by the extended infrastructure for logging purposes.
Marsh mongoose ( Atilax paludinosus) and long-nosed mongoose ( Herpestes naso) are the most numerous small carnivores offered in rural bushmeat markets in the country.
In the late 1990s, fresh and smoked bonobo ( Pan paniscus) carcasses were observed in Basankusu in the Province of Équateur in the Congo Basin.
The main species killed by bushmeat hunters in Tanzania's Katavi Region-Rukwa Region include impala ( Aepyceros melampus), common duiker ( Sylvicapra grimmia), warthog ( Phacocherus africanus), Cape buffalo ( Syncerus caffer), harnessed bushbuck, red river hog ( Potamochoerus porcus) and plains zebra ( Equus quagga).
A survey in a rural area in southwestern Madagascar revealed that bushmeat hunters target bushpig ( Potamochoerus larvatus), ring-tailed lemur ( Lemur catta), Verreaux's sifaka ( Propithecus verreauxi), Hubbard's sportive lemur ( Lepilemur hubbardorum), fat-tailed dwarf lemur ( Cheirogaleus medius), common tenrec ( Tenrec ecaudatus), grey mouse lemur ( Microcebus murinus), reddish-gray mouse lemur ( M. griseorufus), Madagascan fruit bat ( Eidolon dupreanum) and Madagascan flying fox ( Pteropus rufus).
Outbreaks of the Ebola virus in the Congo Basin and in Gabon in the 1990s have been associated with the butchering and consumption of and . Bushmeat hunters in Central Africa infected with the human T-lymphotropic virus were closely exposed to wild primates.
Anthrax can be transmitted when butchering and eating ungulates. The risk of bloodborne diseases to be transmitted is higher when butchering a carcass than when transporting, cooking and eating it.
Many hunters and traders are not aware of zoonosis and the risks of disease transmissions.
An interview survey in rural communities in Nigeria revealed that 55% of the respondents knew of zoonoses, but their education and cultural traditions are important drivers for hunting and eating bushmeat despite the risks involved.
Results of a study conducted during the Ebola crisis in Liberia showed that socio-economic conditions affected bushmeat consumption. During the crisis, there was a decrease in bushmeat consumption and daily meal frequency. In addition, preferences for bushmeat species stayed the same.
As an alternative to bushmeat, captive breeding of species traditionally harvested from the wild is sometimes feasible. Captive breeding efforts must be closely monitored, as there is risk they can be used to Money laundering and legitimize individuals captured from the wild, similar to the laundering of wild green tree pythons in Indonesia for the pet trade.
