International bushmeat trade originating from West/Central Africa Introduction to species identification Developed by the CITES Secretariat GreenCustoms Knowledge Series No. 25
2 Questions to answer Can species used in the bushmeat trade be identified? How? What are the main groups of species involved, and how can they be differentiated? What precautions are necessary when handling bushmeat? Where can assistance be found?
Bushmeat identification Can species used in the bushmeat trade be identified? –Many species appearing in the bushmeat trade can be identified –However, depending on the state of the specimen (for example, when dealing with dried or cooked/smoked meat), it may not be possible to identify to species level, or even to group level – unless laboratories are able to conduct detailed analyses (e.g. DNA profiling) and compare with reference samples
Bushmeat identification How can species used in the bushmeat trade be identified? –Inspection and comparison with reference materials, photographs etc., while looking for characteristic features –Consultation with experts and national CITES authorities –Assistance from specialized laboratories
Bushmeat identification What is it? Where do I start?
Bushmeat identification Start by considering the main groups –Apes, monkeys –Elephant –Small carnivores –Small antelopes –Pangolins –Rodents –Snakes, lizards, tortoises –Birds
Bushmeat identification How these appear in trade may be very different –Whole carcasses, fresh, frozen, dried or smoked –Cut pieces, fresh, frozen, dried or smoked –Meat, dried or smoked –Cooked items
Bushmeat identification How can specimens be identified? –Whole carcasses (fresh, frozen, dried/smoked) –Parts (fresh, frozen, dried/smoked) –Derivatives Which species are in highest demand internationally, and therefore more likely to be encountered by Customs?
Bushmeat identification There may still be characteristic features that can be used in identification, even if the specimens are cut, dried, smoked or otherwise heavily modified in appearance Photo credit: Teresa Hart Bonobo: face all black, unlike the Chimpanzee which has a pale or mottled face
Bushmeat identification Main characteristics to look for –Skull/head –Body shape –Fur/hair/scales –Leg/feet/claws –Tail length and shape Photo credit: Teresa Hart Pangolin: Covered in thick scales, species can be identified by tail-body length, extent of scales on legs
Bushmeat – mammals and CITES In some cases it is easy to tell if CITES-listed species are involved –All primates are included in Appendix I or II –All wild cats are in Appendix I or II However, for other large groups used for bushmeat, it is not straightforward –Duikers & chevrotains can be Appendix I, II, III or not listed –Some commonly traded mammal species, such as porcupines and large rodents are not listed
Apes, monkeys Chimpanzee (Pan troglodytes) –Large, tailless ape, dark brown to black with brighter face –Face is bare, with pale, mottled or darkly pigmented skin –White hairs grow on the chin in adults of both sexes Photo credit: Thomas Lersch

46 Handling bushmeat specimens The handling of CITES specimens requires careful attention Dead specimens (such as bushmeat) can be dangerous to yourself and others, and can require specialized care and handling When in doubt, do not hesitate to call for specialized and experienced help from CITES authorities or other sources (such as zoo veterinarians and health experts)
47 Handling bushmeat specimens Points to consider when handling bushmeat specimens: –Availability of relevant documents - do you have all the information you need? Do you know the point of origin? –Where to carry out the examination - do you have a secure place where any escapes can be immediately controlled? –Storage facility - if you have to hold the specimens, do you have a suitable facility?
48 Handling bushmeat specimens Points to consider when handling bushmeat specimens: –Health and safety concerns - are you and your colleagues trained to deal with bushmeat specimens? –Do you have the right equipment to ensure the safety of yourself, others? –Are you equipped to deal with cuts, scratches or other minor injuries? –Do you have access to help and advice if needed?
49 Handling bushmeat specimens Points to consider when handling bushmeat specimens: –Availability of experts - can you contact experts who are experienced in dealing with bushmeat? –Do you have their contact details outside working hours? –Other agencies - have you contacted other agencies that may need to be informed (such as the CITES Management Authority)? –Do you have the contact details of people in charge outside working hours?
50 Equipment It is important to keep basic equipment at hand –Surgical gloves, face masks –Antibacterial soap and detergents should be available for the handlers and the handling areas
51 Health Be aware that bushmeat specimens may carry zoonoses, also called zoonotic disease, which are diseases that can be passed from animals to humans Remember, the risk of disease may be greater in illegally- traded specimens that have evaded veterinary or health checks and inspections CITES Team, UK Border Agency
52 Health Diseases carried by animals include Ebola, Marburg virus, hepatitis A and B, green monkey disease, simian deficiency virus (animal AIDS), monkeypox, aspergillosis, botulism, and salmonella There are well over 200 zoonotic diseases Photo credit: Dr. Robert Shongo Monkeypox
53 Health Some examples of zoonoses are: –Salmonellosis, campylobacteriosis, anthrax, brucellosis, E. coli, leptospirosis, plague, shigellosis and tularaemia, from bacteria –Cysticercosis/taeniasis, echinococcosis/hydatidosis, toxoplasmosis and trematodosis, from parasites –Q-fever and other Rickettsial diseases –Rabies, avian influenza, Crimean-Congo haemorrhagic fever, Ebola, and Rift Valley fever, from viruses World Health Organization Find out more at http://www.who.int/zoonoses/en/
Make sure you know who to contact in your country –Health, veterinary departments for experts and technical advice –CITES Management Authority (for CITES-listed species, assistance with identification) –Non-Governmental organizations may be able to assist with identification and handling advice
Summary Many species appearing in the bushmeat trade can be identified For dried/smoked specimens it may not be possible to identify to species level, or even to group level – unless laboratories are able to conduct detailed analyses Some identification characteristics may remain, which can allow a distinction to be made between main groups of species in the bushmeat trade The main groups include apes and monkeys, small carnivores, small antelopes, pangolins, rodents, snakes, lizards, tortoises and birds 56
Summary Main characteristics to look for include the skull/head/horns, body shape, fur/hair/scales, leg/feet/claws, and tail length and shape Dead specimens (such as bushmeat) can be dangerous to yourself and others, and can require specialized care and handling Safe handling of bushmeat requires training, information and equipment, and you may need to call upon specialized assistance Make sure you know who to contact in your country for assistance and advice 57
