It’s Too Hot to Keep Using Pesticides

By Harrison Watson - In These Times, August 15, 2023

Farm workers are being sickened by agrochemicals—and, due to extreme heat, by the PPE they wear to protect themselves.

It’s summer and time to take in the sunshine. But beware: because of climate change, the planet is rapidly warming. Outdoor temperatures are climbing above 100^oF. Raging heat waves are causing debilitating illness and death. In some places, floods sweep through the streets. In others, precipitation is declining and water sources are evaporating. The Union of Concerned Scientists has dubbed this time of year, from May to October, the ​“danger season.”

Humans have not evolved to withstand such levels of heat stress. Still, over 2 million farm workers find themselves out in the fields. Some are suited up in heavy layers of clothing, including flannel shirts, pants, boots, gloves and coveralls. The purpose of this personal protective equipment (PPE) is to shield farm workers from the chemical threats they face from working with and around toxic pesticides and herbicides.

Each year, farmers and farm workers use billions of pounds of pesticides to suppress pests across 250 million acres of crop fields in the United States. The Environmental Protection Agency (EPA) does work to educate farm workers and help them navigate pesticide-treated fields safely. Still, according to the National Agricultural Worker Survey nearly one-third of all farm workers do not receive the annual, mandatory training.

“So some farm workers just don’t know how harmful pesticides are,” says Mayra Reiter, director of the Occupational Safety and Health division at the organization Farmworker Justice. ​“The EPA approves chemicals because they assume that farmworkers will wear PPE, but those farm workers aren’t wearing it.”

Every year, pesticides sicken 300,000 farm workers, according to the U.S. Government Accountability Office. No one has an accurate count of how many of them die.

And the PPE farmworkers need to protect them from these chemicals can’t protect them from the danger sealed therein: Wrapped tight in their PPE, the heat they generate working at a feverish pace has nowhere to dissipate. In some places, a third of farm workers out in the fields suffer from heat-related illnesses every year. 

This is because many farm workers are constrained by the current wage system to ignore workplace hazards or skip water, bathroom and cooling breaks. In several states, farm workers receive ​“piece-rate” wages — that is, instead of an hourly wage, they’re paid by the bucket, bushel or piece of crop they pick.
