Trouble on the Farm
Growing Up with Pesticides in Agricultural Communities
Similarly, EPA’s federal regulation to protect farmworkers, the Worker Protection Standard, does not consider that some of those workers may be children and it does not adequately protect even those children who do remain at home from pesticide residues on parents’ skin, clothing, and shoes.
FindingsNRDC has previously shown that pesticides should be considered one of the top five environmental threats to children’s health. Multiple exposures to pesticides are not unique to farm children. The food on our tables carries residues of the same pesticides that may have poisoned farm children, and our water is increasingly contaminated from agricultural runoff. Some of the same pesticides used in the fields are used in homes, schools, and day care centers. In this report, we further explore the threats to children’s health from pesticides and identify the increased risk to farm children.
Pesticides Around Us
- All children are disproportionately exposed to pesticides compared with adults due to their greater intake of food, water, and air per unit of body weight, their greater activity levels, narrower dietary choices, crawling, and hand-to-mouth behavior.
- Fetuses, infants, and children are particularly susceptible to pesticides compared with adults because their bodies cannot efficiently detoxify and eliminate chemicals, their organs are still growing and developing, and because they have a longer lifetime to develop health complications after an exposure.
- Pesticides can have numerous serious health effects, ranging from acute poisoning to cancers, neurological effects, and effects on reproduction and development.
- Many pesticides that are never used indoors are tracked into the home and accumulate there at concentrations up to 100 times higher than outdoor levels.
- In non-agricultural urban or suburban households, an average of 12 different pesticides per home have been measured in carpet dust and an average of 11 different pesticide residues per household have been measured in indoor air in homes where pesticides are used.
- In an early 1990s nationwide survey of urinary pesticide residues in the general population, metabolites of two organophosphate pesticides, chlorpyrifos and parathion, were detected in 82 percent and 41 percent, respectively, of the people tested.
- In a rural community, all 197 children tested had urinary residues of the cancer-causing pesticide pentachlorophenol, all except six of the children had residues of the suspected carcinogen p-dichlorobenzene, and 20 percent had residues of the normally short-lived outdoor herbicide 2,4-D, which has been associated with non-Hodgkins lymphoma.
Pesticides in Agricultural Areas
- Children living in farming areas or whose parents work in agriculture are exposed to pesticides to a greater degree, and from more sources than other children.
- The outdoor herbicide atrazine was detected inside all the houses of Iowa farm families sampled in a small study during the application season, and in only 4 percent of 362 non-farm homes.
- Neurotoxic organophosphate pesticides have been detected on the hands of farm children at levels that could result in exposures above U.S. EPA designated “safe” levels.
- Metabolites of organophosphate pesticides used only in agriculture were detectable in the urine of two out of every three children of agricultural workers and in four out of every ten children who simply live in an agricultural region.
- On farms, children as young as 10 can work legally, and younger children frequently work illegally or accompany their parents to the fields due to economic necessity and a lack of child care options. These practices can result in acute poisonings and deaths.
Recommendations There are many actions we can take today to reduce the unjust exposure burden borne by farm children, and thereby protect all children from one of the five greatest environmental threats to their health. A summary of NRDC’s recommendations follows, including several actions recommended by farmworker groups over the years. (See Chapter 7 of this report for a fuller description.)
- Pesticide tolerance decisions under the FQPA should consider all the exposures faced by farm children and set food tolerances low enough to protect these children from cumulative health risks.
- U.S. EPA must use an additional safety factor of at least tenfold as required by FQPA to be sure to adequately protect farm children if there is uncertainty about their exposures, or about the toxicity of the pesticide to fetuses, infants, and children.
- The farm Worker Protection Standard should be reevaluated to better protect children who accompany their parents to work in the fields, as recommended by the federal Children’s Health Protection Advisory Committee.
- Phase out Category I acutely toxic pesticides, and phase out use of the most hazardous neurotoxic organophosphate and carbamate pesticides, endocrine disrupters, and carcinogens, while developing and promoting alternative pest management practices.
- Improved reporting systems are necessary for tracking pesticide use and pesticide-related illnesses as recommended by the American Medical Association.
- Pesticides should not be registered for use unless there is an established sensitive and accurate scientific method for measuring residues of that pesticide and its metabolites in food, water, and human blood or urine.
- Regional public laboratories capable of precisely and accurately measuring low-levels of environmental toxicants in environmental media and human tissues should be established. Such laboratories would allow improved surveillance, exposure assessment in research studies, and the ability to respond rapidly to environmental disasters.
- Research should focus on the exposures and health status of farm children, with involvement of communities and farmworker groups in the study design. More data will allow more informed decision-making.
- Subsidized day care should be provided for working families with young children. Farm workers must receive a living wage and benefits, so that their children are not forced to work in order to survive.
- Workers must be informed about the identity of chemicals they may be exposed to, and the known or potential health effects of these chemicals. Only with full knowledge can they take action to protect themselves and their families.
- Pesticide use in and around schools and day care centers should be reduced by requiring that all schools and day care centers have integrated pest management (IPM) programs and by creating buffer zones around schools located in agricultural areas. Parents and teachers must be informed about pesticide use. Hazardous pesticides should not be used in such facilities at all.
- Expanded integrated pest management (IPM) programs and organic farming will ultimately help most in reducing pesticide exposures for our children and grand children.
If farm children are not protected from pesticides, then the U.S. EPA is failing to implement the law, and our society is failing to protect its future. The food on our tables comes at a cost that remains hidden from many people. Although farm children are on the front lines, bearing the brunt of pesticide exposures, other children are not far behind. If we adequately protect farm children, the most exposed children in our society, then we will better protect all children.
