Every now and then our class takes site tours of various places relating to our class topics. We have traveled to the flood plain in the middle of Dar es Salaam to look at potential breeding sites (irrigation channels, coconut shells, empty cans, etc) of the anopheles mosquito (carrier of the malaria parasite). We went in hopes of finding some larvae diving and dipping in the water and to learn how to identify particular mosquito larvae. I now can distinguish between the culex (carrier of lymphatic filariasis) and the anopheles mosquito. It was neat to see the physical science behind the class lectures. It was also challenging to walk along the subsistence farmers growing their crops in a polluted flood plain in the middle of a crowded city while the teacher pointed out potential sources of breeding malaria. These people are some of the poorest of the poor in Dar es Salaam. The areas that surround the flood plain all are shanty towns and slum conditions. How is malaria to be stopped without providing these people with proper places to live away from the malaria vectors? Even if malaria is vanquished, what will be done to ensure that these people don’t die a preventable death from diarrheal diseases?
Another class trip involved a drive to the Lower Ruvu water treatment plant that purifies water coming from the river Ruvu for a large proportion of Dar es Salaam. We witnessed how polluted and murky river water can be properly turned into clean drinking water for a large population of people. This is one of four water treatment plants for the city of Dar es Salaam. The guide on our tour pointed out how the river water has been receding due to population growth along this river. More houses are being built and more small-scale farm plots planted. All these household and farming activities have destroyed the natural landscape around this river and slowly drained the water. In addition, there were also workers standing barefoot in this polluted river around the cement intake. The workers’ job was to shovel the debris (mostly fallen brush and garbage) from the grates in which the water passed through on its way to the water treatment plant. The guide mentioned that even dead bodies and animal carcasses have been found to clog the intake channels so they had to put up smaller grates to filter the incoming water!
Our third class trip took us to the Kanga fabric factory, Urafiki (Friendship) factory, on Morogoro Road outside of city center in Dar es Salaam. (A kanga is traditional cloth worn in East Africa as a skirt, shawl, or head covering and have a swahili verse written on it). It was started in 1968 by the Chinese and owned by the government of Tanzania. It was one of the largest factories in Tanzania, employing over 6,000 workers. During the Ugandan War in 1978-79, the factory had difficulties keeping up production and ended up officially closing in 1994. In 1997 after seeking help from the Chinese, it was agreed to be a joint venture between the Chinese (51%) and Tanzania (49%). Currently the workforce consists of 1,100 workers (18 Chinese and 1,082 Tanzanians who are permanent, contract and day-contract workers).
Walking around the grounds of the factory, there were huge signs of doves, handshakes, and Tanzania and Chinese people standing around together looking happy. In Dar there are several signs of the Chinese “friendship” with Tanzania. There is this kanga Urafiki (Friendship) Factory and also the Sino Friendship Hospital.
The conditions at this factory were also deplorable and the reasons that we came. Our visit was to examine occupational hazards at their worst. Upon arriving at the factory we were given dust masks and ear plugs for our protection. Most of the workers that come everyday to work at this factory, however, did not have ear plugs and dust masks.
We observed the factory’s process from start to finish. From raw cotton until the finished dyed kanga, we were able to tour all of the facilities. Cotton particles and dust swirled throughout the factory and machines spun faster than an eye could count. If a worker forgot to pay careful attention, very few machine guards protected the workers from the debilitating effects of the fast-functioning machines. Highly repetitive and arthritis-inducing tasks became the common work load for many of the workers. Some workers had shoes and others didn’t. All stood on cement floors in a poorly-lit room for 8 hrs a day. Some sat on low-seated chairs weaving minute fibers through a bob. All worked in humid and sweltering conditions.
The worst of all though was the central weaving room. The sounds of the clanging machines could be heard even a few rooms away. It was like a mighty beast, caged in the center of the factory, destroying the hearing all who worked there. I had had my ear plugs in for most of this tour, but decided to unplug the one from my left ear for this part of the tour. I wanted to fully hear the roar of the machines. Our class maybe spent five minutes in this room. After leaving, my left ear rang for about ten minutes and I couldn’t properly hear out of it for the next hour. This is no exaggeration. It was probably a stupid idea to inflict hearing loss upon myself, but it gives you an idea of the intensity of the sound in this room. Those who work in or around this room have severe hearing loss and the factory provides no compensation.
It is a sad state. Occupational hazards are not a consideration in Tanzania, but it makes sense. Some will perform whatever work they can in order to provide food for their families. The workers at this Friendship factory were probably poorly educated and just plain poor. They were not paid well either as the daily pay was not disclosed to us; but it was a source of income in which they could make it another day. Occupational health considers the conditions of those working in harsh environments. It recognizes the need to improve those working conditions not only to the benefit of the employees, but also to the employer. It not just identifies situations that need improvement, but acts to improve those conditions through occupational research and public policy. I am hoping that one day occupational health will be as strong in Tanzania as it is in the United States.

raw cotton from the fields – notice the nice lighting…

We weren’t allowed to take pictures, but I did anyways. The first time though I forgot to turn off the flash! But at least you can see the cotton dust everywhere!
