Bird Flu

Table Mountain management has issued an alert to the public that several cases of bird flu in the penguin colony at Boulders have been confirmed by state veterinary services. It is reiterated that this virus is a very low risk to humans, but is a real threat to domestic poultry. This strain of avian influenza virus (H5N8 strain) has been detected in a range of wild seabirds e.g. swift, sandwich and common terns, African penguins and gannets.

The park is monitoring the situation closely and has now implemented the following precautions

With the exception of visitors on Boulders Beach boardwalk, nobody may access the main breeding colony.

In instances where staff need to go off boardwalks to collect injured birds or hats, camera lens, caps etc dropped by visitors they will limit their access to essential work and then sterilise their boots afterwards – gum boots have been issued and are easier to clean than the normal boot.

Monitoring routes used for moult/nest counts have been reviewed to ensure that staff and Penguin monitors do not walk through the main breeding colony.

Western Cape Veterinary Services, CapeNature, SANParks, the national Department of Environmental Affairs, City of Cape Town, SANCCOB and other seabird rehabilitation centres and private veterinarians are working in close cooperation to monitor the situation and perform further testing.

The Western Cape is most affected. The virus is spread from bird to bird, by contaminated bird faeces and other body excretions, and by handling sick birds. Even though the virus is unlikely to infect humans, precautions should nevertheless be taken. Gloves, shoes, clothes, and other protective gear should be worn if handling birds.

Any equipment including vehicles and protective clothing that could possibly be contaminated should be sterilised.

While the virus is highly pathogenic to chickens and other poultry, the impact on wild seabirds is not that well understood (so far 1 tern and 2 penguins from Boulders have come back positive for H5N8). Closing the colony to visitors is not justified at this stage.

Tips for visitors
Visitors must stay on designated board walks
Visitors should change shoes and clothes if visiting other seabird colonies or poultry farms to prevent contamination from one site to another.
