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?
• 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

• Main characteristics
to look for
– Skull/head

– Body shape
– Fur/hair/scales
– Leg/feet/claws
– Tail length and shape
Pangolin: Covered in thick
scales, species can be identified
by tail-body length, extent of

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

Bushmeat handling
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)
46
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?
47
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?
48
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?
49
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
50
Health
• Be aware that bushmeat specimens may carry zoonoses,
also called zoonotic disease, which are diseases that can
be passed from animals to humans
CITES Team, UK Border Agency
• Remember, the risk of disease may be greater in illegallytraded specimens that have evaded veterinary or health
checks and inspections
51
Health
Photo credit: Dr. Robert Shongo
• 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
Monkeypox
52
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

Assistance
Assistance
• 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
