The Environmental Protection Agency’s newest farm worker–safety proposal is haunted. A recommendation for extensive changes to the EPA’s forty-year-old Worker Protection Standard, the proposal, which was available for public comment until August 18, would improve safety, training, and hazard communication policies for agricultural pesticides, including insecticides, herbicides, fungicides, and other chemicals used to control agricultural weeds and pests. The proposed rule would also—for the first time in the United States—set a minimum age for all work with pesticides. But while it has the potential to make an impact, it is still dogged by the numerous false starts, exclusions, and double standards that have long characterized U.S. regulation of agricultural employment, leaving farm work among the nations’ most dangerous jobs.
Exposure to hazards including high heat, heavy machinery, stoop labor, and pesticides makes occupational illness uncommonly common among the United States’s estimated 2.5 million farm workers. They are at risk for a number of acute and chronic health problems, including heat stress, injuries, respiratory conditions, musculoskeletal ailments, reproductive health disorders, dermatitis, and cancer. Pesticide poisoning represents a critical fraction of this toll. Due to underreporting and gaps in oversight, data on farm worker health are hard to come by, but government estimates of acute pesticide poisoning range from 51 to 1,400 cases per year per hundred thousand workers. That is 1,275 to 35,000 cases annually. If the more conservative figure is correct, farm workers are still thirty-nine times more likely than other laborers to face acute pesticide poisoning. And this does not include any of the long-term or chronic illnesses—among them numerous cancers, neurological problems, asthma, immune problems, and birth defects—linked to pesticide exposure in adults and children.
Despite these dangers, U.S. law historically has left farm workers largely unprotected. Two foundational pieces of twentieth-century labor legislation explicitly excluded agricultural laborers. The National Labor Relations Act of 1935 omitted farm workers from its promised right to organize unions and bargain collectively. And the 1938 Fair Labor Standards Act excluded them from its goal of achieving the “standard of living necessary for health, efficiency, and general well-being of workers.” Revisions of the FLSA have not extended overtime rules to farm workers or ensured that all of them receive the federal minimum wage. Perhaps most incredibly, it was not until 1987 that federal law required agricultural employers to provide workers with drinking water, hand-washing facilities and toilets at work.
These exclusions and delays have been tolerated in part thanks to the myth of the independent family farmer, supposedly unable to tolerate basic regulations—a myth that has endured even as agriculture has corporatized, mechanized, and come to rely mainly on wage rather than family labor.
But more significant is the stingy nativism that presumes to benefit from immigrant labor without assuming any responsibility to protect the humans who provide it. This is not just a recent phenomenon. In his famous 1935 study of California’s “factories in the field,” the journalist Carey McWilliams observed, “Sources of cheap labor in China, Japan, the Philippine Islands, Puerto Rico, Mexico, the Deep South, and Europe have been generously tapped” to form the “vast army of workers” employed in industrial agriculture. Beginning in 1942, the bracero program formalized a system in which the U.S. government acted as a labor broker, placing Mexican workers in farm employment while maintaining tight control of their movement and trying to guarantee their eventual return to Mexico.
The National Labor Relations Act and and the Fair Labor Standards Act explicitly exclude agricultural workers.
Immigrants from Mexico and to a lesser extent Central America continued to make up a large proportion of U.S. farm workers after the bracero program ended in 1964. Today immigrants are a majority of the nation’s farm work force, with many of them undocumented and some here as guest workers under the bracero-like H2-A visa. As anyone following recent debates on immigration reform knows, immigrants—especially those entering without documentation—face barriers to political participation, giving a conspicuously uneven pitch to the field of regulatory debate.
This was true even during the late twentieth century sea change in health and environmental regulation. The year 1970 saw the first Earth Day and, after half a decade of organizing and boycotts, the signing of a major contract between grape growers and the United Farm Workers union. It was also the year President Richard Nixon signed legislation establishing the Occupational Safety and Health Administration (OSHA) to “assure safe and healthful working conditions for working men and women” and secured Congressional approval for a new Environmental Protection Agency.
In the first half of the ’70s, the sphere and extent of farm worker safety regulation was up for grabs. While workers lobbied for robust protections, rule making was impeded by lack of data and by the disproportionate influence of agricultural employers who sought minimal regulation. Critics maintained that the EPA’s first pesticide safety recommendations, introduced in 1972, were weakened by industry influence. The Migrant Legal Action Program, a farm workers’ group, prodded OSHA to step in, hoping it would do a better job. The following year, OSHA responded with an emergency rule on pesticide safety. However, after facing opposition from Congress and a lawsuit from growers, OSHA dropped the issue. By 1974, while farm worker advocates were suing the Department of Labor to get OSHA back on the case, the EPA passed the first Worker Protection Standard, effectively asserting its authority over chemical safety on farms.
The original Standard has been modified once before, in a conflict-ridden process that stretched from 1983 to 1992. Comments on the current proposal suggest that it, like that earlier revision, pits labor and environmental groups against agricultural employers. Looking at some key aspects of the proposal in light of the past shows where today’s version improves on history, and where it does not go far enough.
Don’t Spray Workers
The most basic aspect of the Standard, as the 1974 version put it, is “a prohibition against applying pesticides when unprotected workers are in the area being treated.” In other words, don’t spray or fumigate or dust workers with toxic chemicals.
But this simple rule is complicated by the phenomenon of drift: pesticides, because of wind or overspray, may end up outside the target application area. Drift is probably the number one culprit when it comes to worker poisoning: a recent article by National Institute for Occupational Safety and Health researcher Geoffrey Calvert and colleagues fingered drift as the largest single source of pesticide poisoning, responsible for 1,216 of 3,271 acute pesticide poisoning cases reported between 1998 and 2005. The 1974 standard acknowledged drift but included no specific rule to protect workers from it. The 1992 revision made a marginal improvement, instituting buffer zones for some greenhouses and nurseries. Rules for other agricultural workplaces—farms as we usually understand them, as well as forests—have remained silent on the issue.
The proposed revision takes drift seriously, requiring that workers be evacuated not only from land targeted for pesticide application, but also from a buffer zone extending a hundred feet in all directions. This could go a long way toward reducing exposures and correcting the problems of the previous Standard, especially if the proposal’s drift loopholes are closed. Perhaps the most telling loophole shrinks a buffer zone if it happens to cross a property line, suggesting that bureaucracies of ownership trump health. But biology doesn’t end with property boundaries. The Standard could instead require notification of adjacent property owners and expansion of appropriate buffer zones into neighboring parcels. More simply, it could forbid chemical applications along boundary lines. Indeed, doing so is the only way to hew to the central requirement of pesticide safety: don’t spray workers.
Of course, the hazards posed by pesticides don’t disappear immediately after application. Residues on plants and soil and in the air continue to pose health risks. So another central tenet of pesticide safety is to delay return to recently sprayed areas. During the “reentry interval,” it is illegal to access the treated area due to health risks. Reentry intervals are complicated to devise, as the period of danger after application depends on variables including the type of pesticide, mode of application, and the weather. The original Standard set a vague interval for most pesticides—allowing reentry “after sprays have dried or dusts have settled”—along with twenty-four to forty-eight hour waiting periods for areas treated with any of twelve highly toxic pesticides. The 1992 revision strengthened some reentry protections, and today chemical-specific intervals are specified for each individual pesticide. However, loopholes and other problems remain, and the intervals have not been effective. According to the Calvert study, early entry after application is the second most common cause of pesticide poisoning.
The proposed revision to the Standard would help ensure workers know when a recently treated field should not be entered. Currently employers can simply tell workers not to enter an area where a pesticide has been applied, unless the pesticide label itself calls for written notification. But verbal warnings are ineffective because they are difficult to enforce. Imagine a farm worker—possibly an undocumented immigrant, worried that a complaint will cost her job or land her in an ICE detention center—complaining that her boss didn’t issue an oral warning that a reentry ban was in effect. Without written notifications and recordkeeping requirements, it is the employer’s word against the worker’s, making it unlikely that violations will be reported or punished.
The revision would improve safety by requiring posted “no entry” signs at areas treated with the most dangerous chemicals, those with reentry intervals longer than forty-eight hours. The signs, with a red hexagon evocative of a stop sign, portray a “stern-faced man with an upraised hand” and the phrase “entry restricted” in English and Spanish.
Posted warnings likely would do more to preserve workers’ health, but because pesticides with shorter reentry intervals are excluded, workers will still be exposed to acute effects from, for example, glyphosate, commonly known under its Monsanto brand name RoundUp. The chemical has an interval of only four hours, yet it is third on Calvert’s list of the fifteen most common active ingredients causing poisonings in their study.
The current proposal also would allow workers wearing protective gear to enter recently treated fields as long as bosses explain the specific tasks and required protections, as well as keep a record of that information. Labor and environmental groups, including Farmworker Justice and the United Farm Workers are calling for a ban on early entry under any circumstances.
Knowledge Is Necessary for Safety
The “Right to Know” has been at the core of occupational health since the late 1970s. In 1983 OSHA issued a Hazard Communication Standard, which required employers to provide workers with labels, training, and “Safety Data Sheets” containing toxicity information on every chemical they came into contact with. OSHA’s new standard came close to impinging on the EPA’s territory, leading to a negotiation that ended with the EPA in charge of pesticide rules on the farm. This arrangement has not worked in farm workers’ favor: more than thirty years after OSHA set its Hazard Communication Standard, the EPA has not required employers to give most farm workers any chemical-specific information about the pesticides they come into contact with. Currently only pesticide “handlers”—those who mix, load, or apply pesticides—must be informed. The proposed revision would change that, finally ensuring farm workers the same access to information that other workers have benefitted from for three decades.
The revision also includes provisions for improved pesticide safety training. Employers would have to train workers sooner (after two rather than five days of work), more frequently (retraining every year instead of every five years), and more effectively (by assuring trainers are well qualified). Employers also would be required to keep records of training content and participants, adding some bite to the currently toothless Standard, which requires training but “does not require agricultural employers to document that they provided the training . . . [or] require trainers or employers to record who they trained, what training they provided, or when they provided pesticide safety training.” Trainings under the re-imagined Standard would also show workers how to report violations of safety education requirements and employer retribution against whistleblowers.
Protecting Young Workers
For the 6 percent of farm workers who are under age eighteen, pesticide exposure is particularly dangerous. Children and adolescents’ growing bodies and age-specific behaviors mean they are at special risk for learning and developmental disabilities, asthma, cancer, genetic damage, and endocrine disorders. Despite these dangers, even young farm workers get short shrift when it comes to federal protections. The law allows children as young as twelve (and under some circumstances, even younger) to work on farms, while most other jobs have a minimum age of fourteen. Farm workers under age sixteen are prohibited from working any job deemed hazardous, including those that involve handling the most harmful pesticides. But they are allowed to handle other chemicals, including some whose active ingredients have been implicated in a high number of poisonings. In other sectors, workers aren’t allowed to enter highly hazardous jobs until they are eighteen; in agriculture that age is sixteen.
Under our current immigration laws, the people who grow the bulk of our food lack human rights protections.
The revised Standard tightens the rules by establishing that same age, sixteen, as the minimum for handling any pesticide, not just those with the highest toxicity ratings. The new Standard would also prohibit the use of young people as early entry workers during the post-application interval. This is a meaningful change because, as the proposal notes, in one study of 531 acute poisonings among child farm workers, in cases where the toxicity category of the responsible pesticide was known, “67% of the illnesses were associated with toxicity category III pesticides, which are not currently prohibited under the hazardous order.” On the EPA’s scale of I to IV, with I the most toxic, category III can be plenty dangerous. Again the example of RoundUp is instructive. Currently there are no age restrictions for handling this category III chemical, but a 2008 study found that farmworkers exposed to it are twice aslikely to develop Non-Hodgkin’s lymphoma.
Why sixteen? Why not eighteen, as in other hazardous industries? The EPA estimated that raising the cut-off to eighteen would cost “$11 per agricultural establishment and $320 per commercial pesticide handling establishment per year.” This was enough to reject protections for sixteen and seventeen year olds. Extending the reentry prohibition to age eighteen would cost roughly a dollar more per establishment per year. These expenses are minimal compared to the costs—ethical, social, and economic—of poisoning children. How much will it cost to treat cases of disease? The EPA doesn’t try to count.
Enforcement is Key
Even the best regulations are meaningless without adequate enforcement. In 1999 the General Accounting Office, now the Government Accountability Office, concluded that the “EPA has little assurance that the Worker Protection Standard is being adequately implemented and enforced for farm workers generally.” This is because the agency had been “inconsistent” in its dealings with the states, which are responsible for enforcing the Standard. The EPA pays them to do it. But the EPA had not told states how many inspections they must conduct or even defined what an inspection must include. The GAO found five states that had conducted zero inspections in 1998; eleven others had carried out fewer than five.
The EPA has since developed more thorough inspection policies. In 2013, 3,663 inspections found 1,342 violations of the Standard. One hundred and ten of these cases resulted in a fine, civil complaint, or referral from the state to federal level. Warnings were given in response to 332 violations, while in 445 instances alleged violators claimed exemptions because they were operating family farms. Two-hundred and sixty-seven led to some “other enforcement action.” The remaining violations presumably went unpunished.
The best way to ensure adequate enforcement is to provide workers—who experience job conditions first hand—with ways to report breaches and ensure they are not repeated. The proposed Standard makes progress in this regard. It includes training on reporting violations and mandates that required safety information displays include contact information for local enforcement agencies. But workers could have more impact. Occupational health is protected best when laborers, through their own health-and-safety committees, have a significant role in developing training, carrying out inspections, and setting workplace safety priorities.
Equality for Farm Workers
The Standard alone cannot right more than seventy-five years of unequal treatment. Other labor laws must also be amended to give the men, women, and children who work in the fields of this country full rights and protections. The National Labor Relations Act still holds that “the term ‘employee’. . . . shall not include any individual employed as an agricultural laborer,” depriving even unionized farm workers of typical union and collective bargaining protections. The Fair Labor Standards Act also retains its exceptions, leaving farm workers without overtime pay and without a minimum wage on farms employing few workers. And among the estimated 50 percent of farm workers who are undocumented immigrants, fears of detention and deportation limit labor organizing, access to health care, and freedom of movement.
Under our current immigration laws, the people who grow the bulk of our food lack human rights protections. Without such protections and a clear path to citizenship for those who wish to stay in the United States, a large portion of the farm workforce will not have the stability and security fundamental to any true definition of health, no matter what the Standard says.
The proposed Standard is a step in the right direction; with changes it would be stronger. But it is only within a larger framework for worker and immigrant rights that it can succeed in exorcising the ghosts of the past.
