August 30, 2011, San Diego CA. Ralph Collier of the Shark Research Committee
estimated the shark to be a 10-12 ft long Great White. No surfer was touched by the
shark and few seemed aware of it’s presence. http://surftherenow.com.

The risk of being attacked by a Great White shark off a WA beach has
climbed to one in a million.

- pre-harvest: ↓ pathogen load

22. Zoonoses in the developing world
› US$20 billion direct, US$200 billion indirect costs on global economies
during past decade World Bank: People, Pathogens and Our Planet. Washington: 2010
› zoonoses ↓ human health, ↓ income, ↓ status
› low and middle income countries ‒ high dependency on animals
- food, transport, draft power …
- 500‒900 million poor raise livestock
- close contact with animals in poor rural areas, urban slums
› increased risk of food-borne diseases
- poor food safety systems
- unhealthy livestock products that cannot be marketed e.g. anthrax

23. Panic as anthrax kills two
news update
By Boniface Gikandi and Amos
Kareithi
Two people have died following an
anthrax outbreak in Maragua and
Samburu districts.
A 73-year-old man died on Monday
while undergoing treatment at
Murang'a District Hospital while a
seven-year-old boy died in Samburu
district.
The man, Kamau Kega, was among
the first victims to test positive for the
anthrax virus following an outbreak in
Ichagaki location in Maragua.
