Milk

Milk is delicious. Providing it's fresh and does not come in a brik after been UHT'ed and traveled for 5000 miles to get here.
Unfortunately, the last kind is the only kind available in Yaoundé (oh, and the powdered milk à la Nido etc). If you're lucky you can find fresh powdered milk on the market, sent down from the North or North West of Cameroon. Because there you can find milk. There, people have a tradition of herding cows, making yogurt and cheese. 
So when a friend and I found out that there IS in fact fresh milk, only it doesn't get to Yaoundé we decided to change that. 
We found a dairy in Kumbo, the Tadu Dairy Cooperative, that was willing to try it out. That was more than a year ago. 
Since then, we've set up a regular dairy delivery to Yaoundé of fresh milk, yogurt and butter. It's quite a challenge to get the dairy (and especially the milk) down and cold as it should. Kumbo is a 7 hours drive away, and that's on a good day without traffic. 
This is how it's usually done: 
We send the Dairy our order (and that of 80+ other milk lovers in Yaoundé) and a week later it arrives. The Dairy puts everything in big coolers filled with ice bottles. They drive the order up to Bamenda where it gets loaded on top of the night bus. Overnight, it travels down to Yaoundé and arrives here in the early morning nice and cold.
We've been having orders for over 350 liters of milk and more than 500 yogurts (of different tastes) and so far, none of it has arrived bad. 
The Tadu Dairy Cooperative is a cooperative that has had quite some funding and support from (mainly) US organisations such as Land O' Lakes, USAID and others. They are now completely independent and provide mainly the North West of Cameroon with yogurt, butter, cheese etc. More information on the success story of Tadu Dairy Cooperation you can find here.
