In their natural state, reptiles present almost no health
threat to humans as a result of the micro-organisms these animals carry. |
 |
Captivity places tremendous stress on reptiles, and changes their natural
microbiology in a way that increases illness in the animals leading to high
levels of early morbidity. The majority of reptiles do not even survive
their first year in captivity. |
 |
Because captive reptiles are prolific carriers of salmonella and other
micro-organisms, they can be a major cause of disease in humans. In February
2000, Prof Liam Donaldson, Chief Medical Officer for the UK Department of
Health, advised that children under five, pregnant women and the elderly
should avoid all contact with reptiles. |
 |
Reptile handlers acquire disease as a direct result of contact with the
animal - whether from faeces, urine, skin or saliva - or the animal's cage,
provisions, furnishings or water supply. |
 |
Salmonella is a common bacteria associated with human disease, but reptiles
additionally carry worms and ticks which also can cause illness. It has
been shown that relevant microorganisms may survive for long periods in
the general environment, in tap water for three months, and in faecal material
for up to two and a half years. Transmission routes can also be highly indirect
- e.g. through an intermediary host or inanimate object. |
 |
At the height of the U.S. terrapin trade in the mid 1970s, there were
280,000 cases of turtle-related salmonellosis in humans. Pet stores attempted
to educate their staff and the public about the dangers of keeping reptiles,
but these efforts failed. Thus the U.S. Food and Drug Administration introduced
a nation-wide ban on the trade in terrapins in 1975. Canada followed suit
in 1976. |
 |
Most people who deal with exotic reptiles have only a vague knowledge
of the disease risks associated with such animals. By buying these animals,
the public unwittingly runs the risk of bringing reptile-associated disease
into their homes. |
