Exposure, perception and institutional response at the abattoir community interface: quantifying the environmental-justice gap in complaint driven regulation in Bo and Kenema Cities, Sierra Leone
This study of Sierra Leone's abattoir communities reveals that while residents accurately perceive environmental risks, the current complaint-driven regulatory system disproportionately serves the most vocal and exposed households, systematically excluding unaware and less vocal residents despite widespread facility deficiencies.

In many cities across sub-Saharan Africa, the places where animals are slaughtered for food are often located right next to where people live. These facilities, known as abattoirs, are essential for feeding a growing population, but they come with a heavy cost for the neighbors. The air can carry strong, unpleasant smells, the water can become contaminated with waste, and the area can attract swarms of flies and rodents. For years, scientists and public health officials have known that these environmental problems create a burden for nearby communities. However, a deeper question has remained unanswered: do the people living there actually realize how much risk they face, and does the government system designed to protect them respond when they speak up?
This question touches on two important ideas. First, there is the concept of risk perception, which is simply how a person judges a danger. Sometimes people feel safe even when they are in danger, or they feel terrified when the risk is low, depending on how much they trust authorities or how familiar they are with the hazard. Second, there is the idea of environmental justice, which suggests that the people who suffer the most from pollution are often the ones with the least power to stop it. If a city only fixes problems after someone complains, it might miss the people who are suffering the most but are too unaware, too tired, or too afraid to make a noise.
A team of researchers from Njala University in Sierra Leone decided to investigate this dynamic in two cities, Bo and Kenema. They wanted to see if the residents' feelings about their health matched the actual physical conditions around the slaughterhouses, and to trace exactly what happened when a resident tried to file a complaint. They did not just ask people what they thought; they also went out and measured the real-world conditions, counting the flies, checking the waste, and noting the smells. They also visited the slaughterhouses themselves to see how the workers were managing their facilities.
The researchers found that, generally, the people living near these slaughterhouses were very good at sensing danger. When the air smelled bad or the water was dirty, the residents felt it. In fact, the more pollution a person was exposed to, the more likely they were to say they felt at risk. This suggests that the community is not blind to the hazards around them; they are accurate detectors of their own environmental burden. In the city of Kenema, where the conditions were worse, more people reported feeling a high health risk compared to Bo. Overall, about one-third of the people surveyed said the slaughterhouse posed a high or very high risk to their health, and many supported moving the facility to a different location.
However, the story becomes more complicated when looking at who actually gets help. The study revealed a gap between suffering and speaking up. While most people could sense the danger, a significant number of those who were exposed to the worst smells did not even realize that the slaughterhouse was the cause. Nearly 30 percent of the people living in the most odorous areas were unaware that a slaughterhouse was nearby. Because they did not connect their bad smell to the source, they never filed a complaint.
For those who did complain, the system worked, but only for a specific group. The researchers found that the people who were suffering the most were also the ones most likely to complain. When the smell was unbearable, the rate of complaints jumped from a tiny fraction to over a quarter of the residents. Yet, the system was not equally responsive to everyone who spoke up. Among those who complained, the chance of getting a response from the authorities depended heavily on how bad their situation was. In the areas with the least pollution, only a small handful of complaints received any action. But in the areas with the most severe pollution, more than half of the complaints led to some form of institutional response.
This creates a double exclusion. The regulatory system, which relies on people filing complaints, ends up serving the people who are both suffering the most and are loud enough to be heard. It systematically leaves behind two groups: the people who are suffering quietly because their burden is just below the threshold of complaint, and the people who are suffering loudly but do not know who to blame. The study also found that the slaughterhouses themselves were in poor condition. Most of the 16 facilities inspected lacked basic protective gear for workers, had no handwashing stations, and dumped their waste openly on the ground.
The researchers conclude that while the community knows the danger, the current way the government handles these problems is flawed. By waiting for people to complain, the system misses the most vulnerable people who either do not know the source of their trouble or cannot find the energy to speak. The authors suggest that the rules should change. Instead of waiting for a citizen to report a problem, officials should use direct measurements of the environment—like checking the smell, the waste, and the number of insects—to decide when to intervene. This would ensure that help arrives based on the actual burden of pollution, rather than on the ability of a resident to navigate a complex complaint process.
