Farm workers in the Kenyan horticultural town of Timau are falling sick from suspected pesticide poisoning, and dozens are now seeking to join a lawsuit against the government and agrochemical companies. The case challenges the sale of highly hazardous pesticides (HHPs) in Kenya.
Timau, a town of about 10,000 people in central Kenya, has hosted horticultural companies for decades. These companies employ thousands of local workers, many of whom have fallen ill over the years, with some dying young. Their relatives blame pesticides.
What Happened to Reuben Muriki?
Reuben Muriki, now 30, worked as a pesticide sprayer at a flower farm. Several years ago, he fainted while doing a chore at home. That was the start of increasingly serious health episodes: swollen joints, discolored skin, and difficulty breathing.
Doctors treated him for suspected tuberculosis, but the treatment failed. His mother, Margaret Mwanjaro, recalls that he would often fall and lose consciousness. Today, Muriki cannot walk on his own, speaks incoherently, and quickly forgets things. His mother provides round-the-clock care.
Mwanjaro believes her son's condition is the result of poisoning from the pesticides he sprayed on the flower farm. Muriki is now one of 87 people seeking to join a court petition against the Kenyan government and agrochemical companies.

Why Pesticide Use Is Rising in Kenya
Pesticide use has risen to record levels in Kenya as farmers seek higher yields and improved food security. However, the increased use of HHPs has raised concerns about worker safety and environmental health.
HHPs are defined by the World Health Organization as pesticides that present a particularly high risk to health or the environment. They include substances that are carcinogenic, mutagenic, or toxic to reproduction, among other hazards.

Many HHPs are banned or restricted in high-income countries but remain available in Kenya and other lower-income countries. This discrepancy is at the heart of the legal challenge.
The Legal Petition Against HHPs
The petition seeks to challenge the sale and use of HHPs in Kenya. It argues that the government has failed to protect workers and the public from the dangers of these chemicals.

The case also targets agrochemical companies that manufacture or distribute HHPs. The petitioners claim that these companies have a responsibility to ensure their products are safe when used as directed.
If successful, the petition could lead to stricter regulations on HHPs in Kenya, potentially setting a precedent for other countries in the region.

Key Takeaways
- Farm workers in Timau, Kenya, are falling ill from suspected pesticide poisoning, with some dying young.
- Reuben Muriki, a former pesticide sprayer, is now unable to walk or speak coherently.
- 87 people are seeking to join a court petition against the Kenyan government and agrochemical companies.
- Pesticide use in Kenya has risen to record levels, including highly hazardous pesticides (HHPs).
- The lawsuit challenges the sale of HHPs, which are banned or restricted in many high-income countries.
Comparing Pesticide Regulations
| Country/Region | Status of HHPs | Key Regulation |
|---|---|---|
| European Union | Banned or severely restricted | EU Pesticides Database |
| United States | Restricted; some HHPs allowed with controls | EPA regulations |
| Kenya | HHPs still available; under legal challenge | Pest Control Products Board |
What This Means for Workers and Consumers
For workers like Muriki, the consequences of pesticide exposure can be devastating. Many workers lack adequate protective equipment or training, and they may not be aware of the long-term health risks.
For consumers, the presence of pesticide residues on exported produce is a concern. Kenya is a major exporter of flowers, vegetables, and fruits to Europe and other markets. If HHPs are found on exports, it could lead to trade restrictions.

The lawsuit could prompt companies to adopt safer alternatives and improve worker safety. It may also encourage the Kenyan government to strengthen its regulatory framework for pesticides.
What to Watch Next
The court will decide whether to allow the 87 petitioners to join the case. If allowed, the case will proceed to a full hearing, which could take months or years. The background to this story is set out in Global Pesticide Poisoning Crisis Affects 46% of Farmers Annually. A related thread runs through Elephant Deaths in Kenya: Cyanide Poisoning from Pesticides.
In the meantime, advocacy groups are calling for immediate action to protect workers. They argue that the government should suspend the use of HHPs until the case is resolved. Earlier coverage in Elephant Deaths in Kenya Linked to Cyanide Poisoning shows how the argument developed. A closer look at the same subject appears in Elephant Deaths in Kenya: Cyanide Poisoning from Farms.

The outcome of this case could have far-reaching implications for agricultural practices in Kenya and beyond. It may also influence international discussions on pesticide regulation and corporate responsibility.
