Pesticides and environmental injustice in the USA: root causes, current regulatory reinforcement and a path forward

Many environmental pollutants are known to have disproportionate effects on Black, Indigenous and People of Color (BIPOC) as well as communities of low-income and wealth. The reasons for these disproportionate effects are complex and involve hundreds of years of systematic oppression kept in place through structural racism and classism in the USA. Here we analyze the available literature and existing datasets to determine the extent to which disparities in exposure and harm exist for one of the most widespread pollutants in the world – pesticides. Our objective was to identify and discuss not only the historical injustices that have led to these disparities, but also the current laws, policies and regulatory practices that perpetuate them to this day with the ultimate goal of proposing achievable solutions. Disparities in exposures and harms from pesticides are widespread, impacting BIPOC and low-income communities in both rural and urban settings and occurring throughout the entire lifecycle of the pesticide from production to end-use. These disparities are being perpetuated by current laws and regulations through 1) a pesticide safety double standard, 2) inadequate worker protections, and 3) export of dangerous pesticides to developing countries. Racial, ethnic and income disparities are also maintained through policies and regulatory practices that 4) fail to implement environmental justice Executive Orders, 5) fail to account for unintended pesticide use or provide adequate training and support, 6) fail to effectively monitor and follow-up with vulnerable communities post-approval, and 7) fail to implement essential protections for children. Here we’ve identified federal laws, regulations, policies, and practices that allow for disparities in pesticide exposure and harm to remain entrenched in everyday life for environmental justice communities. This is not simply a pesticides issue, but a broader public health and civil rights issue. The true fix is to shift the USA to a more just system based on the Precautionary Principle to prevent harmful pollution exposure to everyone, regardless of skin tone or income. However, there are actions that can be taken within our existing framework in the short term to make our unjust regulatory system work better for everyone.

Differences in Heat-Related Mortality by Citizenship Status: United States, 2005-2014

OBJECTIVES

To determine whether non-US citizens have a higher mortality risk of heat-related deaths than do US citizens.

METHODS

We used place of residence reported in mortality data from the National Vital Statistics System from 2005 to 2014 as a proxy for citizenship to examine differences in heat-related deaths between non-US and US citizens. Estimates from the US Census Bureau American Community Survey of self-reported citizenship status and place of birth provided the numbers for the study population. We calculated the standardized mortality ratio and relative risk for heat-related deaths between non-US and US citizens nationally.

RESULTS

Heat-related deaths accounted for 2.23% (n = 999) of deaths among non-US citizens and 0.02% (n = 4196) of deaths among US citizens. The age-adjusted standardized mortality ratio for non-US citizens compared with US citizens was 3.4 (95% confidence ratio [CI] = 3.2, 3.6). This risk was higher for Hispanic non-US citizens (risk ratio [RR] = 3.6; 95% CI = 3.2, 3.9) and non-US citizens aged 18 to 24 years (RR = 20.6; 95% CI = 16.5, 25.7).

CONCLUSIONS

We found an increased mortality risk among non-US citizens compared with US citizens for heat-related deaths, especially those younger and of Hispanic ethnicity.

Health of men, women, and children in post-trafficking services in Cambodia, Thailand, and Vietnam: an observational cross-sectional study

BACKGROUND

Trafficking is a crime of global proportions involving extreme forms of exploitation and abuse. Yet little research has been done of the health risks and morbidity patterns for men, women, and children trafficked for various forms of forced labour.

METHODS

We carried out face-to-face interviews with a consecutive sample of individuals entering 15 post-trafficking services in Cambodia, Thailand, and Vietnam. We asked participants about living and working conditions, experience of violence, and health outcomes. We measured symptoms of anxiety and depression with the Hopkins Symptoms Checklist and post-traumatic stress disorder with the Harvard Trauma Questionnaire, and used adjusted logistic regression models to estimate the effect of trafficking on these mental health outcomes, controlling for age, sector of exploitation, and time in trafficking.

FINDINGS

We interviewed 1102 people, of whom 1015 reached work destinations. Participants worked in various sectors including sex work (329 [32%]), fishing (275 [27%]), and factories (136 [13%]). 481 (48%) of 1015 experienced physical violence, sexual violence, or both, with 198 (35%) of 566 women and girls reporting sexual violence. 478 (47%) of 1015 participants were threatened and 198 (20%) were locked in a room. 685 (70%) of 985 who had data available worked 7 days per week and 296 (30%) of 989 worked at least 11 hours per day. 222 (22%) of 983 had a serious injury at work. 61·2% (95% CI 58·2-64·2) of participants reported symptom of depression, 42·8% (39·8-45·9) reported symptoms of anxiety, and 38·9% (36·0-42·0) reported symptoms of post-traumatic stress disorder. 5·2% (4·0-6·8) had attempted suicide in the past month. Participants who experienced extremely excessive overtime at work, restricted freedom, bad living conditions, threats, or severe violence were more likely to report symptoms of depression, anxiety, and post-traumatic stress disorder.

INTERPRETATION

This is the first health study of a large and diverse sample of men, women, and child survivors of trafficking for various forms of exploitation. Violence and unsafe working conditions were common and psychological morbidity was associated with severity of abuse. Survivors of trafficking need access to health care, especially mental health care.

Evaluation of a community-based participatory farmworker eye health intervention in the "black dirt" region of New York state

BACKGROUND

Eye irritation is a constant hazard for migrant and seasonal farmworkers, but there are few studies of the problem or how to address it. Researchers evaluated the effect of a community-based participatory eye health intervention on farmworker eye symptoms in the Hudson Valley, NY.

METHODS

A randomized pre-post intervention with 2, 4-week follow-up periods was implemented with a sample of 97 farmworkers. Five eye symptoms were measured, along with utilization of protective eyewear and eye drops.

RESULTS

Leading baseline eye symptoms were redness (49%), blurred vision (43%), itching (43%), and eye pain (29%). Significant reductions in eye pain (P = 0.009), and non-significant reductions in redness were observed for the intervention group while controls experienced increases in both.

CONCLUSIONS

The intervention was effective in significantly reducing eye pain, and to a lesser extent, redness. Future eyewear promotion programs should offer a range of eye wear, tailor offerings to local climate and tasks, evaluate eyewear durability, and include eye drops.

Barriers and facilitators for promotoras' success in delivering pesticide safety education to Latino farmworker families: La Familia Sana

Despite widespread use of lay health advisor (LHA) programs, factors related to success of LHAs remain largely unexamined. This study describes experiences and personal transformations of LHAs (promotoras de salud) in a pesticide safety education program targeting farmworker families in North Carolina, using postintervention in-depth interviews conducted with 17 LHAs. LHAs identified assets and barriers that affected their success. LHAs also described increases in self-efficacy and empowerment resulting in perceived improvements in ability to teach and impact their community. Such positive changes are essential benefits to the LHAs. Evaluations that address these topics are needed to better understand continuity and attrition in LHA programs.

Dermal exposure associated with occupational end use of pesticides and the role of protective measures

BACKGROUND

Occupational end users of pesticides may experience bodily absorption of the pesticide products they use, risking possible health effects. The purpose of this paper is to provide a guide for researchers, practitioners, and policy makers working in the field of agricultural health or other areas where occupational end use of pesticides and exposure issues are of interest.

METHODS

This paper characterizes the health effects of pesticide exposure, jobs associated with pesticide use, pesticide-related tasks, absorption of pesticides through the skin, and the use of personal protective equipment (PPE) for reducing exposure.

CONCLUSIONS

Although international and national efforts to reduce pesticide exposure through regulatory means should continue, it is difficult in the agricultural sector to implement engineering or system controls. It is clear that use of PPE does reduce dermal pesticide exposure but compliance among the majority of occupationally exposed pesticide end users appears to be poor. More research is needed on higher-order controls to reduce pesticide exposure and to understand the reasons for poor compliance with PPE and identify effective training methods.

Migrant and seasonal crop worker injury and illness across the northeast

BACKGROUND

Northeast farmworkers are a small, widely dispersed, and isolated population. Little is known about their occupational injury and illness risk.

METHODS

Researchers conducted chart reviews in migrant health centers across the Northeast, and calculated incidence-density for agricultural morbidity based on a new method for estimating total worker hours at risk, and adjusting for cases seen at other sources of care.

RESULTS

An estimated annual average of 1,260 cases translated to an incidence of 30.27 per 10,000 worker weeks, (12.7 per 100 FTEs). Straining/spraining events (56% cases) was the most common occurrence (16.8 per 10,000 worker weeks), and lifting (21.5% cases) was the leading contributing factor. Incidence by crop category ranged from 12.95 (ground crop) to 29.69 (bush crop) per 10,000 weeks. Only 2.8% filed for Workers' Compensation.

CONCLUSION

The predominance of straining/spraining events affecting the back, and their association with lifting suggests that Northeastern farmworker occupational health programs should focus on ergonomics, and specifically on safe lifting.

Health status of migrant farmworkers in the Shenandoah Valley

The purpose of this study is to describe the characteristics and health status of a sample of migrant farmworkers in the Shenandoah Valley. The methodology for this study is a retrospective record review and analysis of data on 390 male migrant farmworkers. The group included men from Mexico (57. 2%), Jamaica (26. 9%), and Haiti (13. 0%) with a mean age of 38.5 years. The most common health problems reported were work-related and included musculoskeletal pain, irritated eyes, and respiratory symptoms. This study identifies areas for community and public health nurses to target interventions to address health promotion/disease prevention efforts.

Informal occupational safety information exchange among Latino migrant and seasonal farmworkers

Latino farmworkers in North Carolina are a hard-to-reach population that faces diverse occupational health risks, including pesticide exposure. Health and safety education efforts often employ lay health advisor or promotor(a) de salud models in which farmworker community members are trained to provide health education. As a frequently tight-knit and isolated group, farmworkers may be well suited to serve as resident lay health advisors. This paper presents data collected from a nonrandom sample of Latino farmworkers living in North Carolina regarding the natural level of occupational safety information exchange among Latino farmworkers, specifically pesticide safety information. The data affirm that farmworkers informally exchange occupational safety information with one another, with the level of exchange increasing during the agricultural season. Consequently, if trained, the data suggest that farmworkers might be situated to provide in situ occupational health and safety education to their peers. This remains to be systematically tested and evaluated.

Risk factors for musculoskeletal disorders among farm owners and farm workers: a systematic review

BACKGROUND

A systematic review was undertaken to establish risk factors for the development of musculoskeletal disorders (MSDs) among farmers.

METHODS

Comprehensive electronic searches of Pubmed, Web of Science, CINAHL, SCOPUS, EMBASE, Agris Database, and Cochrane Library were carried out using a battery of key words for MSDs and farmers. The studies methods quality was assessed using a standardized checklist.

RESULTS

Thirty-three studies fulfilled the inclusion criteria. The median method score was 65% of the maximum attainable score, resulting in 15 studies of higher methodological. Risks were categorized into: Work characteristics (n = 11), personal characteristics (n = 5), and psychosocial factors (n = 5). Spinal MSD risk factors include exposure to working in tree crops, vibration, postural load, being an owner operator, age, education beyond high school, suffering from asthma or depression, having <8 hr nightly sleep, bad quality sleep, and geographic location. Upper extremity MSD risk factors include being an owner operator, dust with pig workers, numbness and coldness in younger milkers and numbness in milkers >43 years, age, and body height in dairy farmers. Lower extremity MSD risk factors include, duration of farming ≥10 years, working >5 hr daily in animal barns, milking >40 cows, years as a dairy farmer, farm work, age, body mass, and female gender.

CONCLUSIONS

In exploring risk factors the spine was the most researched body region, followed by lower and upper extremity. Given the variance between studies, it is recommended that future studies focus on specific types of farmers and should explore specific exposures for specific body parts using standardized case definitions.

Prevalence of musculoskeletal disorders among farmers: A systematic review

OBJECTIVE

To determine the prevalence of musculoskeletal disorders (MSDs) among farmers and to establish the most common regional MSDs reported.

METHODS

Comprehensive electronic searches of Pubmed, Web of Science, CINAHL, SCOPUS, EMBASE, Agris Database, and Cochrane Library were carried out using keywords for MSDs and farmers. Pooled estimates of prevalence with 95% confidence intervals were calculated for overall MSD prevalence and the most common regional MSDs reported.

RESULTS

Twenty-four studies fulfilled the inclusion criteria and were incorporated into this review. From these studies, life-time prevalence of any form of MSD among farmers was 90.6% while 1-year MSD prevalence was 76.9% (95% CI 69.8-82.7). The majority of studies focused on spinal MSDs with low back pain (LBP) the most frequently investigated. Life-time LBP prevalence was 75% (95% CI 67-81.5) while 1-year LBP prevalence was 47.8% (95% CI 40.2-55.5). The next most common regional MSDs reported were upper (range 3.6-71.4%) and lower extremities (range 10.4-41%).

CONCLUSIONS

The systematic review identified the prevalence of MSDs by body region in farmers and established that LBP was the most common MSD, followed by upper and then lower extremity MSDs. Reported trends suggest that the prevalence of MSDs in farmers is greater than in non-farmer populations. Case-definition uniformity among MSD researchers is warranted. More studies are needed regarding upper and lower extremity MSDs, gender, workplace, and task context of MSDs.

Overcoming language and literacy barriers in safety and health training of agricultural workers

The workforce in all areas of United States agriculture and forestry is becoming increasingly diverse in language, culture, and education. Many agricultural workers are immigrants who have limited English language skills and limited educational attainment. Providing safety and health training to this large, diverse, dispersed, and often transient population of workers is challenging. This review, prepared for the 2010 Agricultural Safety and Health Council of America/National Institute for Occupational Safety and Health conference, "Be Safe, Be Profitable: Protecting Workers in Agriculture," is divided into five sections. First, we describe the occupational and demographic characteristics of agricultural workers in the United States to highlight their safety and health training needs. Second, we summarize current research on the social and cultural attributes of agricultural workers and agricultural employers that affect the provision of safety and health training. Worker and employer attributes include language, literacy, financial limitations, work beliefs, and health beliefs. Third, we review current initiatives addressing safety and health training for agricultural workers that consider worker language and literacy. These initiatives are limited to a few specific topics (e.g., pesticides, heat stress); they do not provide general programs of safety training that would help establish a culture of workplace safety. However, several innovative approaches to health and safety training are being implemented, including the use of community-based participatory approaches and lay health promoter programs. Fourth, the limited industry response for safety training with this linguistically diverse and educationally limited workforce is summarized. Finally, gaps in knowledge and practice are summarized and recommendations to develop educationally, culturally, and linguistically appropriate safety and health training are presented.

Chronic back pain and associated work and non-work variables among farmworkers from Starr County, Texas

OBJECTIVES

This study estimated the prevalence of chronic back pain among migrant farmworker family members and identified associated work and non-work variables.

METHODS

Migrant farmworkers (n = 390 from 267 families) from Starr County, Texas were interviewed in their home once a year for 2 years. The original survey included items measuring demographics, smoking, sleep, farm work, and chronic back pain. For this cross-sectional analysis, multi-level logistic regression was used to identify associated work and other variables associated with chronic back pain while accounting for intraclass correlations due to repeated measures and multiple family members.

RESULTS

The prevalence of chronic back pain during the last migration season ranged from 9.5% among the youngest children to 33.3% among mothers. Variables significantly associated with chronic back pain were age (odds ratio [OR], 1.03, per year increase), depressive symptoms while migrating (OR, 8.72), fewer than 8 hours of sleep at home in Starr County (OR, 2.26), fairly bad/very bad quality of sleep while migrating (OR, 3.25), sorting crops at work (OR, 0.18), and working tree crops (OR, 11.72).

CONCLUSION

The role of work exposures, depressive symptoms, and sleep in chronic back pain among farmworkers warrants further examination. Refinements in outcome and exposure assessments are also needed given the lack of a standardized case definition and the variety of tasks and crops involved in farm work in the United States.

Promoting the occupational health of indigenous farmworkers

In the United States, approximately 78% of agricultural farmworkers are immigrants. In Oregon, a growing number of these farmworkers are indigenous and speak an indigenous language as their primary language. This group of farmworkers suffers from linguistic, cultural and geographic isolation and faces a unique set of challenges yet little has been done to identify their health needs. Using data from focus groups, partners from this community-based participatory research project examined indigenous farmworkers' concerns regarding occupational injury and illness, experiences of discrimination and disrespect, and language and cultural barriers. The data revealed examples of disrespect and discrimination based on the languages and cultures of indigenous farmworkers, and a lack of basic occupational health and safety information and equipment. For example, participants mentioned that occupational safety information was inaccessible because it was rarely provided in indigenous languages, and participants felt there were no legal means to protect farmworkers from occupational hazards. Community-based strategies designed to address the occupational health status of farmworkers must consider the unique circumstances of those farmworkers who do not speak Spanish or English.

Factors associated with pesticide safety practices in farmworkers

BACKGROUND

Farmworkers and their families are exposed to pesticides through multiple pathways. Few studies have examined the frequency with which farmworkers engage in pesticide safety practices and the factors associated with their adoption.

METHODS

Using a large sample of farmworkers (n = 554), we evaluated relationships between pesticide safety behaviors and farmworkers' beliefs, training history, handling of pesticides at work, perceived occupational exposure, and employers' provision of personal protective equipment.

RESULTS

Performing behaviors at work was determined largely by whether personal protective equipment was provided. For home behaviors, female gender, living in a labor camp, being trained in the last 5 years, handling pesticides directly, and not perceiving organizational barriers to protecting oneself were associated with taking more precautions.

CONCLUSIONS

These findings call for interventions that involve and engage multiple stakeholders to increase adoption of pesticide safety behaviors and reduce pesticide exposure in farmworkers.
