Bushmeat in Canada

-->
The April 22 issue of Maclean’s magazine carried a story by reporter Sarah Elton about bushmeat. I don’t know if she also came up with the title, Gorillas in our midst but it was a nice pun on the Diane Fossey book title and subsequent movie Gorillas in theMist

A similar article titled Monkeys on the menu  appeared in the April 15 on-line version of the magazine

It was good to see this important issue highlighted, but as someone who has witnessed the bushmeat trade first-hand and written about it in some detail I found that there were some missing elements that should have been covered.  I wrote the following letter to the magazine’s editor and in due course received a reply telling me that it had been forwarded to Ms Elton.

Of course I had the luxury, in my book The Trouble With Lions (U of Alberta Press 2008) of being able to explore the subject outside the restrictions of the kind of word limit required in a magazine article, but I believe that the disease issues I raised are important.

Here is the letter, unedited from what I sent, but with two of my own pictures slotted in at appropriate spots, as I cannot use the ones from the magazine.

Dear Mr. Stevenson,

Sarah Elton’s story on bushmeat, with its clever punning title Gorilla in our midst is, like the curate’s egg of Punch cartoon fame, good in parts. She misses a few really important points. I have worked in Africa for many years and also written books and blogs on the continent’s wildlife. I have three chapters in my book The Trouble With Lions that cover this subject in some detail. The third one is titled Bushmeat and Bureaucrats. Like the members of this corps worldwide it seems that Canadian ones are slow to act.

I realize that Elton was constrained by a word limit, but the Photoshopped image of the gorilla head on the meat counter made a nice point and was perhaps a worthy replacement for the 1000 extra words the article needed. She has however either missed out on or is misinformed about disease risks.

Foot and mouth disease is endemic in much of Africa and all cloven-hoofed species are susceptible. Canada’s last outbreak of this economically disastrous plague occurred in Saskatchewan in 1952. It was traced back to the importation of smoked meat from Poland. Bushmeat from Africa poses at least as great a risk.

Monkey pox is misnamed (not Elton’s fault). It is a disease of rodents – remember the outbreak in the USA that was linked to pet gophers in 2003. People in Africa, desperate for protein are eating species once considered taboo. The Wakamba of Kenya, a tribe famed as hunters, are amongst them.

Egyption fruit bats in a cave in Queen Elizabeth NP in Uganda
Fruit bats, a common bushmeat item, carry Ebola and the closely related Marburg virus. Both are deadly to humans. For several years I took senior veterinary students to Uganda and a highlight was a visit to a cave in Queen Elizabeth National Park that was the daytime home to an estimated 100,000 bats. That stopped after an unfortunate Dutch woman who had visited the cave contracted Marburg and died at home in Holland. The cave is now off-limits to all.

AIDS is a disease that crossed from primates into humans at least seven times in the 20th century. There are two main virus types, HIV1 and HIV2. 

A chimp feeding on fruit in Uganda
Beatrice Hahn, a professor at the University of Alabama showed that chimpanzees are the source of HIV1 while sooty mangabeys, a small almost uniformly grey monkey from West Africa are the source of HIV2. Even more fascinating is that the two viruses in humans are less closely related to one another than they are to their original primate hosts.

I realize that in this little précis I have exceeded the 300-word limit, but I do have lots of other examples and I also quoted Dr. Brashares in my book. I also have good pictures of those fruit bats and of a local bushmeat vendor with whom I had a couple of long chats. He is from rural Cameroon and is just trying to make a living in a forest region where livestock cannot be raised.

Yours sincerely

I signed off using my Professor Emeritus status in the hope that I would be taken seriously. I just hope that foot-and-mouth disease does not get into Canada, or indeed North America, through the bushmeat route. This is a real case of my not wanting to be an accurate prophet. 

I have not heard another word, either from the magazine or the author.  Ah well!

Bushmeat in the USA

Talk about serendipity!

Tonight I have a gig with the Saskatoon Nature Society and my topic is The Trouble WIth Lions: A symbol for Africa's wildlife. As I indicated I am using the lion only as a symbol and I have added an extra subtitle in my opening slide which is (and other continents).
I took this picture in Cameroon in 1997. In it you can see several species for sale as bushmeat. The three at bottom left are smoked monkeys of some kind, but the treatment has rendered them beyond identification, or at least field i.d.
This morning, when I opened up my email I found a letter from my main listServ source on wildlife issues which is theWildlife Disease News Digest, put together by Dr. Cris Marsh of the USDA. One of the links in that document reads Bushmeat Diseases Entering New York and so of course I opened it, as I have been following the bushmeat situation for many years now and my last post about it, of nine, was on Jan 11th. This concerned the trail of the Liberian woman who was convicted last year of trying to smuggle 720 pounds of baboon and warthog meat. She had used the innovative defense that the meat was for religious purposes and claimed the right to freedom of religious expression.

In the online Discovery News of yesterday it was reporter Jennifer Viegas who summarized the newer events and the finding by colleagues in the Wildlife Conservation Society of a virus called simian foamy virus in three primate species: two mangabey monkeys and a chimpanzee. This photo of a sooty mangabey was taken by Nick Gordon and was available n the Arkive image web site. For those familiar with the AIDS story, it was from these very same species that the disease has crossed into humans on at least seven occasions in the last hundred years.

Viegas goes on to report that Inspection and health officials have seized hundreds of samples of wildlife and wildlife products coming through luggage and mail parcels through main entry points for both people and goods into New York City and the United States. Samples have been taken from at least 14 species, including great apes, monkeys, rodents, and bats.

She also states that officials of the U.S. Fish & Wildlife Service say that more than one billion individual animals were imported into the United States from 2000 to 2004, along with over 11 million pounds of bushmeat and other animal products. That’s one billion animals – 1000,000,000!

Is this the forerunner of a coming plague?

Gorillas and AIDS


Linkhttp://wdin.blogspot.com, http://www.promedmail.org/, http://news.bbc.co.uk/2/hi/health/8175379.stm, http://www.nature.com/nm/index.html

News that a newly discovered version of the virus that causes AIDS has cropped up in a woman from Cameroon has hit several new outlets. This is no surprise. They include Wildlife Disease News Digest, Promed Ahead and the BBC web site.

The original article was published in the prestigious journal Nature Medicine. Lead author Jean-Christophe Plantier and his eight colleagues describe the finding of SIV [simian immunodeficiency virus] in a gorilla. They state that the virus
"is closely related to gorilla simian immunodeficiency virus (SIVgor) and shows no evidence of recombination with other HIV-1 lineages. This new virus seems to be the prototype of a new HIV-1 lineage that is distinct from HIV-1 groups M, N and O. We propose to designate it HIV-1 group P."


It has already been established that the two most important versions of the virus (so far) are HIV1, which crossed into humans from chimpanzees some time in the last 100 years somewhere in the Congo basin and HIV2 which came from a small nondescript monkey called the sooty mangabey, a small, almost uniformly grey monkey whose range is restricted to Upper Guinea in West Africa. In humans these two viruses are genetically less closely related to one another than they are to their original primate sources. The SIV counterparts of these two forms of HIV have been introduced into humans on at least seven different occasions.

That gorilla SIV should have crossed into a human should not surprise anyone who has followed the history of the bushmeat trade. In his 1963 autobiography On Safari Armand Denis published several remarkable photographs of gorillas that had been hunted by large gangs of Ituri hunters deep in the forests of the Congo basin. He had accompanied pygmies on a well-orchestrated hunt in the forest.

However, the Cameronian woman was living in Paris and had never been in contact with bushmeat. The article’s authors suggest that she must have acquired the infection from someone else who was carrying it. While this is the first finding of its kind, it seems likely that others will now be made. The patient was not ill, but that does not mean she will not develop AIDS.
