Vulnerable populations such as impoverished persons, children, and workers including migrant laborers, farmworkers, and hospitality workers are at increased risk of pesticide exposure and poisoning. These workforce groups are less likely to be aware of safety information, protective gear, and specific health risks of using pesticides. Concerns of potential retribution or loss of employment and language barriers can lead them to avoid seeking healthcare or initiating a discussion about exposures when receiving care. Additionally, workers may not recognize that their symptoms could be related to pesticide exposure or know where to find the names of specific products.
Family physicians play a critical role in assessing exposure risks. A national protection standard, the Worker Protection Standard (WPS), is a federal regulation that aims to reduce pesticide poisonings and injuries among agricultural workers and pesticide handlers (Pesticide Educational Resources Collaborative, n.d.). The WPS requires agricultural employers to comply with minimum safety precautions, but this protection is not well known amongst clinicians.
Impoverished persons have increased exposure risks for several reasons. Low-income housing is often located adjacent to areas where pesticides can be found in the water, soil, air, and building materials. These individuals often have fewer healthcare resources and face potential housing loss or other recrimination if exposures are reported. Additionally, they are more likely to experience occupational exposure if they work in the hospitality, janitorial, and food service industries.
Children are the population most profoundly impacted by pesticide poisoning. Pesticides can affect cognitive and physical development and are linked to numerous types of pediatric cancers and chronic diseases. Due to metabolic, behavioral, and physical characteristics, children are much more likely to experience serious effects from toxic exposures at lower doses than adults. Children living in homes with family members who work in high-risk industries are even more vulnerable due to secondhand exposure to chemicals on clothes and equipment. This type of exposure is often not considered in clinical settings. Additional pediatric exposures and mechanisms of injury should be on clinicians’ minds, as the following is considered: “Farm labor can be legally performed by children as young as twelve years of age under the Fair Labor Standards Act, with no minimum age for children working on small farms or family farms. Child labor in agriculture is common, with as many as 500,000 child farmworkers estimated to work in the U.S.” (Children's Health Protection Advisory Committee, 2021, p. 1).
Family medicine clinicians can be vigilant in seeking out possible pesticide exposures while taking histories and performing physicals for high-risk patients. This fact sheet lists related history-gathering tools that will be helpful in this endeavor and recommends networking with community health workers (U.S. Department of Health and Human Services, 2014) who may function as patient advocates, resource coordinators, and patient educators. Recognition and Management of Pesticide Poisoning is a comprehensive, easily digested resource detailing pesticide exposure and treatment that is easy to reference during patient visits (PERC-med, n.d.). This presentation provides clinical guidance on recognizing pesticide poisonings in ambulatory care settings.
Family physicians can help the PERC-med team advocate for increasing awareness and training of clinicians to diagnose and treat excessive and/or prolonged pesticide exposure.
Agriculture is known as one of the most dangerous industries for farm owners, workers, and their families, who live, work, and play in the same spaces. “Those working in the agricultural industry producing food, fiber, and fuel experience one of the highest risks factors among all occupations for injury, illness, and death” (Donham, 2016). The U.S. Department of Labor, Occupational Safety and Health Administration states that farmworkers are exposed to numerous safety, health, environmental, biological, and respiratory hazards (OSHA, n.d.). The United States is one of four significant producers of agriculture globally, and in 2016, a reported 1.2 billion pounds of pesticides were used in the United States, ranking America second to China in pesticide usage (Donley, 2019). Furthermore, the U.S. Environmental Protection Agency (EPA) estimates that almost 75% of U.S. households use pesticides (U.S. EPA, n.d.). Pesticides are used in agriculture to control weeds and other unwanted vegetation, insects, rodents, bacteria, fungi, and diseases.
The USDA Census of Agriculture data shows that the number of women in agriculture is increasing, with women accounting for 36% (1.2 million) of the country’s producers (USDA, 2017). Pregnancy and fertility are often not considered when women assume farm tasks. The EPA states, “Women who are pregnant or planning a pregnancy, especially those currently performing farm work, should be informed of the implications of [pesticide] exposure before, during, and after pregnancy and assisted in making appropriate decisions for their work and home situations” (U.S. EPA, 2013).
Populations at significant risk of pesticide poisonings and adverse effects include pregnant women and children who reside in agricultural communities. Incidents of pesticide poisonings often go unnoticed without proper education, including prevention, and this leads to adverse effects such as neural tube defects, neurodevelopmental harm, spontaneous abortion, and cancer.
In a published PLOS One study focused on environmental exposure screenings by OB/GYNs, fewer than half of the physicians surveyed screened for occupational exposures, including pesticide use (Grindler et al., 2018). In addition, 85% of respondents reported that they did not feel comfortable obtaining an environmental history, and 58% of respondents said that they performed no regular screening of environmental exposures. Family physicians have a critical role in serving as the first line of defense for pregnant women working and living in agricultural communities. Occupational and environmental medicine recommend routine screening for environmental and occupational exposures to identify, monitor, and reduce prenatal exposures. Considerations for routine patient screening include:
Family physicians are uniquely positioned to serve as the first line of defense for pregnant women, infants, and children exposed to pesticides. Please visit Pesticide Educational Resources Collaborative-Medical (PERC-med) for more population-specific resources.

Family medicine practitioners play a key role in preventing and mitigating the health effects of pesticide exposures. The COVID-19 pandemic has been accompanied by a sharp increase in the use of antimicrobial pesticides—disinfectants—as infection control measures surge.1,2 This upward trend highlighted the lack of consumer knowledge around common pesticide exposures and the potentially hazardous effects of such products deployed for disinfection purposes. It’s important that family medicine physicians are equipped to not only recognize signs of pesticide poisoning but also to help patients understand when and how they may be exposed to pesticides in everyday settings.
Pesticides are substances that are used to prevent, kill, and/or mitigate pests and are most often used to prevent illness in humans or damage to crops.3,4 There are hundreds of pesticide active ingredients incorporated into an enormous number of readily available products. Pesticides include insecticides, herbicides, fungicides, rodenticides, molluscicides, nematicides, and others.5 While pesticides are effective because they disrupt biological processes in the targeted pests, they can lack high selectivity, making them potentially hazardous for humans.3,4
Pesticides can pose health risks to humans through mechanisms of impairing biochemical targets. Targets include enzymes such as acetylcholinesterase (AChE) and cytochrome c reductase, ion channels, and receptors.3 For instance, organophosphorus pesticides are often neurotoxic because of their inhibition of AChE in neuromuscular junctions and other areas of the central nervous system.6,7 Similarly, organochlorine pesticides are toxic because of enzyme inhibition and effects on metabolism and transcription.8 Pesticide type; exposure amount, route, and duration; and the susceptibility of the exposed individual affect health outcomes.7
Given the non-specific symptoms associated with pesticide poisoning, it is important physicians have accurate patient information to assess relevant risk. A pesticide exposure scenario can occur at home, at work, or through hobbies. Recognition and Management of Pesticide Poisonings provides a comprehensive guide to aid clinicians. Family medicine clinicians may consider advising patients who spend time around pesticides—such as gardeners or golfers—how to reduce exposure. Similarly, clinicians in areas known to have higher pesticide usage rates may consider incorporating pesticide exposure prevention education into routine clinical care.
There are an enormous number of pesticide products on the market ranging from pet flea collars and common household disinfectant wipes to garden-ready herbicides and sprays used across agricultural lands. There are inherent health risks associated with such products. Family medicine physicians[KM1] who are knowledgeable about the vast array of products and can identify active ingredients may be able to more readily identify pesticide-related health conditions. Screening for both acute and chronic exposure provides concrete information for reducing health risks. Screenings could include questions about occupation and hobbies, as well as common household products.
With known or suspected exposure, treatment is the clear priority. While pesticide reporting requirements for physicians providers[KM2] vary across the country, reporting is mandatory in over 60% of states. Learn about requirements in your state of practice here.
Poison Control Center data shows over 35,000 calls related to pesticide exposure concerns for children ≤5 years old in 2018. Most serious acute poisonings occur after unintentional ingestion, although poisoning may also follow inhalational exposure or significant dermal exposure, such as in drift events. Misuse, such as violating label instructions, may also lead to overexposure. It is well recognized that pesticide poisonings are likely to be underreported because of difficulty with diagnosis, incomplete reporting and symptoms not being recognized as a poisoning. High-risk children may include those who:
Pesticides are toxic by design. Insecticides and rodenticides are most commonly associated with acute pediatric poisoning. Warfarin-type rodenticides are also a significant ingestion risk for young children. Many insecticide chemical classes designed to be neurotoxic for insects have been shown to be neurotoxic in humans, such as the cholinesterase-inhibiting organophosphate and carbamate insecticides and the pyrethroids. Toxicity varies by the active ingredient(s) and formulation.
Many signs and symptoms related to acute pesticide exposure are nonspecific and resemble other common childhood illnesses. Diagnosis depends on identifying an exposure and determining that the exposure scenario was likely to lead to significant uptake and the signs and symptoms experienced.
Determine if the child might have been exposed to pesticides in suspected illness events.
Determine if the pesticide of concern is associated with the signs and symptoms. The EPA’s Recognition and Management of Pesticide Poisonings offers a comprehensive online Index of Signs and Symptoms organized by pesticide class.
Linkage of signs and symptoms to pesticide exposure, further workup, and poisoning management may require specialist consultation. For poisoning management, contact the Poison Control Center (800-222-1222). The regional Pediatric Environmental Health Specialty Units (PEHSU) programs can provide consultation for subacute concerns, post-acute phase questions, or assistance in determining pesticide active ingredients and potential toxicity.
Cholinesterase testing may be useful for guiding the early treatment of suspected organophosphate and carbamate poisoning. Preserved urine or clothing samples may be useful for future analysis as evidence of exposure or to assist in public health investigations. Samples should be obtained as soon as possible as many pesticides metabolize quickly.
Clinician reporting of suspected pesticide-related illnesses is required by law in many states. Regardless, clinicians should notify the local or state public health department or state pesticide regulatory agency if the exposure source may present a hazard to others or if help is desired in identifying an environmental exposure source. State-specific reporting requirements can be found at PERC-med.

Davis, California -- A free course to train health professionals to recognize, treat and report pesticide poisoning and illnesses in California has been expanded to provide information on reporting requirements throughout the nation.
The California Office of Environmental Health Hazard Assessment (OEHHA) has joined forces with the Pesticide Educational Resources Collaborative for Medical Professionals (PERC-med) to expand the reach of the 60-minute online course. The continuing medical education (CME) program, titled Recognition, Management and Reporting of Pesticide Illness, provides medical information on the recognition and management of symptoms of pesticide poisoning. It also presents information on how to diagnose and treat pesticide illnesses, including those due to cholinesterase-inhibiting pesticides.
The original course, designed by OEHHA for health care providers in California, contained information on reporting requirements of pesticide illnesses in the state. A national module created by PERC-med has been added to the course.
With the addition of this new module, providers across the United States will find information on reporting pesticide illnesses in their specific state. The information is designed to be useful to hospitals, physicians, nurses, physician assistants, health centers, medical students, and first responders.
The course can be accessed through the PERC-med website at pesticideresources.org/med/resources/training.html or through the OEHHA website at oehha.ca.gov/pesticides/education-and-training.
"The addition of the reporting module extends the reach of this course to a national audience," said Dr. Ouahiba Laribi of OEHHA, CalEPA, and the PERC-med Advisory Board. "The national expansion ensures a comprehensive training for health-care providers, with health benefits for all US residents, especially people in agricultural areas."

A pesticide is any substance or mixture of substances intended for preventing, destroying, or mitigating any pest. Children and pregnant women are uniquely vulnerable to toxic effects from exposure to pesticides. Some of the widely used pesticides of concern in the United States include the herbicide glyphosate, organophosphate insecticides (e.g., chlorpyrifos, malathion), carbamate insecticides (e.g., carbaryl, propoxur), neonicotinoid insecticides (e.g., imidacloprid, thiamethoxam), and pyrethroid insecticides (e.g., permethrin, cypermethrin). Chronic or repeated low-dose exposures are common. There is growing evidence on the relationship between this non-acute pesticide exposure in early life and adverse neurocognitive and neurobehavioral outcomes (ADHD, autism) in children. Additional associated morbidities include cancer (brain tumors, leukemia) and adverse birth outcomes (reduced intrauterine growth, preterm birth, congenital anomalies, fetal death).

You may be surprised to learn that many infection control products commonly used in healthcare are actually pesticides.
More specifically, they are antimicrobial pesticides. Antimicrobial pesticides are essential public health tools because we use them in hospitals, schools, bathrooms and food preparation areas to prevent the spread of germs that can cause disease. So, what exactly constitutes a pesticide? A pesticide is defined as any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest. Microorganisms, bacteria and viruses are included in the definition of pests. Pesticides help protect our food, water, and health. However, there are always risks related to their use.
Given global challenges with the COVID-19 pandemic, an increasing number of antimicrobial pesticides are being used to help control the spread of the novel coronavirus, SARS-CoV-2, that causes COVID-19. Since the emergence of COVID-19, the demand for antimicrobial pesticides has risen sharply. A recent CDC Morbidity and Mortality Weekly Report, found that U.S. poison centers received an increase in calls (45,550) related to exposure to cleaners (28,158) and disinfectants (17,392) from January–March 2020, compared to January–March 2019 (37,822) and January–March 2018 (39,122). Although this data does not provide a definite link between exposures and COVID-19 related cleaning activity, a clear temporal association can be seen (Chang, 2020).
