As far as I understand it, you are supposed to be accredited in the country in which you guide, train, (practice as a doctor) etc. The MDT (
www.mdt.za.org ) is SA's body that is responsible for accreditation for mountaineering in South Africa.
After the programme, I wondered what sort of accreditation Carte Blanche has that allows it to report.

Surely a reporter worth anything should have tried to interview the Tanzanian operator and guide and looked at what accreditation is necessary in that country to guide.
It seems that much of the report was an attack on ADI with it being interesting that they did not mention the other company or tour operator on whose trip another client died.
What it did highlight was the need for proper accreditation of mountain guides.
It might also have highlighted other issues such as why the Tanzanian authorities/government does not provide medical equipment like oxygen or a compression bag at the camps. They are after all the ones milking the mountain and from numerous reports do hardly anything in the way of putting anything back (eg like toilets).
