Assessment of personal protective equipment use among farmers in eastern North Carolina: a cross-sectional study

The association of chronic bronchitis and airflow obstruction with lifetime and current farm activities in a sample of rural adults in Iowa

OBJECTIVE

Farmers have an increased risk for chronic bronchitis and airflow obstruction. The objective of this study was to investigate the association of these health outcomes with farm activities.

METHODS

We evaluated the Keokuk County Rural Health Study (KCRHS) enrollment data for farm activities and the two health outcomes chronic bronchitis based on self-reported symptoms and airflow obstruction based on spirometry. We used logistic regression to model the health outcomes, yielding an odds ratio (OR) and 95% confidence interval (95% CI) for farm activities while adjusting for potential confounders and other risk factors.

RESULTS

Of the 1234 farmers, 104 (8.4%) had chronic bronchitis, 75 (6.1%) fulfilled the criteria for airflow obstruction, and the two outcomes overlapped by 18 participants. Chronic bronchitis without airflow obstruction (n = 86) had a statistically significant association with crop storage insecticides (OR 3.1, 95% CI 1.6, 6.1) and a low number of years (≤ 3) worked with turkeys (OR 3.3, 95% CI 1.2, 9.4). The latter result should be interpreted with caution because it is based on a small number of cases (n = 5). Airflow obstruction with or without chronic bronchitis (n = 75) was significantly associated with ever working in a hog or chicken confinement setting (OR 2.2, 95% CI 1.0, 4.5).

CONCLUSIONS

These results suggest that work with crop storage insecticides or turkeys may increase the risk for chronic bronchitis and work in hog or chicken confinement may increase the risk for airflow obstruction.

Evaluation of Personal Protective Equipment Usage Habit of Mining Employees Using Structural Equation Modeling

Background

In occupational studies, it is a known situation that technical and organizational attempts are used to prevent occupational accidents. Especially in the mining sector, if these attempts cannot prevent occupational accidents, personal protective equipment (PPE) becomes a necessity. Thus, in this study, the main objective is to examine the effects of the variables on the use of PPE and identify important factors.

Methods

A questionnaire was implemented and structural equation modeling was conducted to ascertain the significant factors affecting the PPE use of mining employees. The model includes the factors that ergonomics, the efficiency of PPE and employee training, and PPE usage habit.

Results

The results indicate that ergonomics and employee training have no significant effect (p > 0.05) on the use of PPE. The efficiency of PPE has a statistically meaningful effect (p < 0.05) on the use of PPE. Various variables have been evaluated in previous studies. However, none of them examined the variables simultaneously.

Conclusion

The developed model in the study enables to better focus on ergonomics and employee training in the PPE usage. The effectiveness of a PPE makes its use unavoidable. Emphasizing PPE effectiveness in OHS training and even showing them in practice will increase employees’ PPE usage. The fact that a PPE with high effectiveness is also ergonomic means that it will be used at high rates by the employee.

Occupational Contact Dermatitis in Employees of Large-Scale Narcotic Crop Farms of Ethiopia: Prevalence and Risk Factors. A Self-Reported Study Using the Nordic Occupational Skin Questionnaire

BACKGROUND

Occupational skin diseases are the second leading occupational disease, accounting for almost 25% of all missed workdays. Occupational contact dermatitis (OCD) accounts for 70% to 90% of all skin disorders in the workplace. Only a few occupational epidemiology studies have looked into the prevalence and risk factors of occupation-induced dermatitis among narcotic crop farm workers around the world. Related studies in Ethiopia are even fewer.

METHODS

A cross-sectional survey was conducted in the Dirashe district of Southern Ethiopia from March 23 to April 12, 2021. Data was collected using a standardized interviewer-administered questionnaire. The history of contact dermatitis was determined using the standardized Nordic Occupational Skin Questionnaire version 2002 (NOSQ-2002). A total of 578 farm laborers took part in the study, which was conducted using a systematic random sampling. Descriptive statistics and multivariable regression were used to characterize the data and identify factors associated with occupational contact dermatitis.

RESULT

The prevalence of self-reported occupational contact dermatitis in the past 12 months among workers of large-scale Khat farms was (AOR: 67.80%, 95% CI [61.00, 76.23]). In the multivariable regression, being older (AOR: 5.51, 95% CI [1.79, 7.24]), working as a bundle binder (AOR: 5.74, 95% CI [2.12, 15.55]), not wearing personal protective equipment (PPE) (AOR: 2.50, 95% CI [1.64, 3.81]), and having poor knowledge of pesticides use, storage, and disposal methods (AOR: 2.50, 95% CI [1.64, 3.81]) were associated with occupational contact dermatitis.

CONCLUSION

Contact dermatitis caused by work is very common among Khat farm laborers. Measures to promote safe practices and reduce exposure to hazards, such as removing expired and/or banned chemicals, purchasing alternative pesticides that meet legislative requirements, job rotation and routine training of staff on safe practices, increasing safety signage, and performing risk assessments, as well as improving the quantity and quality of institutional protective equipment supplies may thus contribute to the enhancement of safe work practices.

Farmers' health risk and the use of personal protective equipment (PPE) during pesticide application

Personal protective equipment (PPE) is always considered the last and sometimes the most important safety shield against pesticides' hazards health risks. The spread of pests and low-quality pesticides, especially in developing countries, has increased health hazard potential among farmers. The present study aimed to assess farmers' health risks when using PPE (composite index) by exploring its most important predictive factors. A sample of 370 farmers in Ardabil province, Iran, was selected based on the multistage sampling method. The results reveal that most farmers use three types of PPE when applying pesticides. Based on their perception of pesticides' health risk, the number of PPE used differs. The highest health hazard in using PPE and the minimum perception of health risks caused by pesticides among farmers are related to the pesticides Paraquat and Chlorpyrifos. Also, the most important predictive factors of the composite index were found to be farm size, pesticides' health risk perception, previous experiences with harmful effects of chemical pesticides on health (especially among large-scale farmers), training courses, and ability to afford PPE-related costs, respectively. Accordingly, farmers' safety and health programs in the region should focus on reducing or replacing the mentioned high-risk pesticides. Reducing government subsidies for high-risk pesticides, establishing government subsidies for farmers' PPE, providing extension training (especially for small-scale farmers), and receiving ongoing training feedback to improve farmers' health risk perception of pesticides and the need to use PPE will effectively reduce farmers' health risks.

Occupational health and safety in agriculture. A systematic review

Introduction: The prevalence of occupational diseases in the agricultural sector is higher than in other industries, since agricultural workers are at higher risk of exposure to different chemicals and pesticides, and are more prone to occupational accidents.Objective: To conduct a review of recent literature on occupational health and risk in agriculture.Materials and methods: A literature search was conducted in PubMed, SciencieDirect and Scopus using the following search strategy: type of articles: original research papers; language: English; publication period: 2006-2016; search terms: "agricultural health", "agrarian health", "risk factors", "epidemiology", "causality" and "occupational", used in different combinations ("AND" and "OR").Results: The search yielded 350 articles, of which 102 met the inclusion criteria. Moreover, 5 articles were found in grey literature sources and included in the final analysis. Most research on this topic has been conducted in the United States, which produced 91% (97/107) of the articles included.Conclusions: Most studies on health and safety in agriculture focused primarily on the harmful effects of occupational exposure to agrochemicals and pesticides, and the consequences of occupational accidents. However, since more than 90% of these studies come from the United States, a more comprehensive approach to health in agriculture is required, since what is reported here may be far from the reality of other regions, especially Latin America.

Revisiting Sustainability of Fungicide Seed Treatments for Field Crops

The use of fungicide seed treatment (FST) is a very common practice worldwide. The purported effectiveness of many fungicides in providing broad-spectrum and systemic control of important diseases and the perception that FST reduces overall pesticide use, hence lowering environmental impacts, have greatly promoted the use of FST in the last five decades. Since there have been rapid advancements in the types, formulations, and application methods for seed treatments, there is a need to re-evaluate the benefits versus the risks of FST as a practice. While the use of seeds treated with neonicotinoid insecticides has come under scrutiny due to concern over potential nontarget effects, there are knowledge gaps on potential negative impacts of FST on operators' (those who apply, handle, and use treated seeds) health and nontarget soil organisms (both macro- and microorganisms). Here we review existing knowledge on key fungicides used for seed treatments, benefits and risks related to FST, and propose recommendations to increase benefits and limit risks related to the use of FST. We found FST is applied to almost 100% of sown seeds for the most important arable crops worldwide. Fungicides belonging to 10 chemical families and with one or several types of mobility (contact, locally systemic, and xylem mobile) are used for seed treatment, although the majority are xylem mobile. Seed treatments are applied by the seed distributor, the seed company, and the farmer, although the proportion of seed lots treated by these three groups vary from one crop to another. The average quantity of fungicide active ingredient (a.i.) applied via seed treatment depends on the crop species, environment(s) into which seed is planted, and regional or local regulations. Cost-effectiveness, protection of the seed and seedlings from pathogens up to 4-5 weeks from sowing, user friendliness, and lower impact on human health and nontarget soil organisms compared with foliar spray and broadcast application techniques, are among the most claimed benefits attributed to FST. In contrast, inconsistent economic benefits, development of resistance by soilborne pathogens to many fungicides, exposure risks to operators, and negative impacts on nontarget soil organisms are the key identified risks related to FST. We propose eight recommendations to reduce risks related to FST and to increase their benefits.

Dataset on cocoa farmers' agrochemical handling practices and safety compliance in Ahafo Ano North district, Ashanti region, Ghana

Agrochemicals are essential but hazardous inputs being utilized at different stages in cocoa production. Safeguarding the health of workers handling these chemicals is therefore of utmost importance. Although Ghanaian government implemented mass spraying of cocoa with every essential occupational safety being followed, non-workability of the programme in many parts of the cocoa producing areas necessitates supplementary application of agrochemicals by many farmers. Therefore, a survey was conducted in Ahafo Ano North district of the Ashanti region in 2015 to understand the compliance of farmers to safety guidelines in handling agrochemicals. The survey was conducted with structured questionnaires that were written in English language and translated into the local language in the course of the interviews. A total of 246 cocoa farmers were interviewed using stratified sampling procedures. The questionnaire, which was divided into four sections solicited information on farmers’ socioeconomic characteristics, safeguard measures being taken by the farmers in the course of handling agrochemicals, health complaints after handling agrochemicals and stress and occupational hazards. The dataset is herewith made available and it is considered of vital usefulness given some serious policy implications of occupational health hazards among cocoa farmers.

Pesticide use, allergic rhinitis, and asthma among US farm operators

OBJECTIVE

The objective of the study is to examine associations between use of specific pesticides and lifetime allergic rhinitis and current asthma in US primary farm operators.

METHODS

The 2011 Farm and Ranch Safety Survey data from 11,210 primary farm operators were analyzed. Pesticide use on the farm was determined using an affirmative response to the question of whether the operator ever mixed, loaded, or applied pesticides on their farm in the 12 months prior to the interview. Operators who answered "yes" were further asked about the specific trade name and formulation identifiers of the product they used and personal protective equipment (PPE) used. Data were weighted to produce national estimates. Adjusted prevalence odds ratios (PORs) were calculated using logistic regression. The referent group included operators who did not use any pesticides in the 12 months prior to the interview.

RESULTS

Of an estimated 2.1 million farm operators, 40.0% used pesticides, 30.8% had lifetime allergic rhinitis, and 5.1% had current asthma. Insecticide and herbicide use were significantly associated with lifetime allergic rhinitis and current asthma. The use of 2,4-dichlorophenoxyacetic acid (POR = 1.5; 95% CI 1.2-1.9) and carbaryl (POR = 2.3; 1.4-3.7) was significantly associated with lifetime allergic rhinitis. Of operators using pesticides, 64.9% used PPE the last time they mixed, loaded, or applied pesticides.

CONCLUSIONS

Pesticide use was associated with lifetime allergic rhinitis and current asthma among farm operators. Further studies are needed to clarify the dose-response relationship between pesticide use and adverse respiratory health effects.

Perceived usefulness of personal protective equipment in pesticide use predicts farmers' willingness to use it

Personal protective equipment (PPE) can substantially reduce the risk exposure from pesticide spraying, but compliance is rather low, particularly among small-scale farmers. In this study the connection between farmers' willingness to use PPE in pesticide handling and perceptions of PPE usefulness was examined through a survey of 341 small-scale farmers in Gorgan county of Golestan Province, Iran. Farmers who were not using PPE when working with pesticides were purposively selected to better serve the objective of the study. Multinomial logit regression models were employed to examine differences in farmers' willingness to use PPE in the future. Almost four out of ten farmers (38.1%) showed willingness to use PPE. However, 36.7% of the farmers showed unwillingness and 25.2% were unsure about using PPE. The average score of farmers' perceptions of PPE disadvantages (x=0.55) was significantly higher than the corresponding score of PPE advantages (x=0.38). Low availability and high price were considered the most important constraints in PPE use by the majority of farmers (75.4% and 74.8% of the farmers, respectively). Farmers who perceived usefulness of PPE, such as effectiveness, safety, and ease of use, were more willing to use PPE in the future. Those who perceived non-usefulness of PPE, driven by unavailability, high price, lack of use by neighbors or colleagues, and ignorance of PPE in extension trainings, were less likely to use PPE in the future. Findings revealed that willingness to use PPE among small-scale farmers when working with pesticides is strongly linked to their perception of PPE usefulness. Findings raise our understanding of the important role of farmers' knowledge in PPE acceptance and use and can motivate policy-makers to pay more attention to the role of farmers' perceptions and awareness in the success or failure of health and safety programs. It is necessary to incorporate farmers' preferences in extension programs to promote safety measures during working with pesticides.

Knowledge, Attitudes, and Practices for Respiratory and Hearing Health among Midwestern Farmers

OBJECTIVE

The purpose of this study was to assess knowledge, attitudes, and practices for hearing and respiratory health/safety among farmers in seven Midwestern states served by a federally funded Agricultural Center. Findings provided a baseline to longitudinally track the Agricultural Center's program outcomes and to design community education to improve safety and health among farmers.

DESIGN AND SAMPLE

This was a cross-sectional study using a 30 item mailed survey to describe farmers' operations, demographics, health conditions, related information sources, and knowledge/attitude/practices for personal protective equipment (PPE) (i.e., ear plugs/muffs and dust masks/respirators).

MEASURES

Frequencies and percentages were calculated for each item and according to responses from younger versus older farmers. The unit of study was farm operators (N = 280) randomly selected from a publicly available database of corn/soybean and hog farmers in seven Midwestern states.

RESULTS

Findings revealed important knowledge gaps among respondents regarding (1) hazardous exposure sources; (2) long-term health consequences of noise/dust exposure; (3) proper selection/fitting of PPE.

CONCLUSIONS

Public health nurses and primary care providers in rural communities should address specific knowledge gaps in order to enhance farmers' perceived understanding of their susceptibility to hazardous exposures. Increasing farmers' knowledge through preferred venues may help to improve PPE effectiveness.

Pesticide knowledge and practice among horticultural workers in the Lâm Đồng region, Vietnam: A case study of chrysanthemum and strawberries

BACKGROUND

In Vietnam, large amounts of pesticides are being used in agriculture. Next to benefits for agriculture, pesticides impose a huge threat to the environment when they are used in the wrong way. The objective of this work was to determine the level of knowledge and awareness of the smallholder farmers towards the use of pesticides in Vietnam, Dà Lat region. Based on the collected data, an occupational and environmental risk assessment was performed.

RESULTS

The results indicate that the majority of the pesticide operators in the strawberry and chrysanthemum crops have a rather high education. Pesticide knowledge, on the other hand, is usually gained through experience with pests and diseases. Only 30% of the farmers consulted a pesticide specialist or government stewardship for information on (new) pesticide products. Pesticide usage is rather high with application frequencies up to once every three days during the wet season. Pesticide packages are stored to be incinerated (51%) or to be thrown away with the garbage/taken to the landfill (37%). Only a small percentage disposes the packages into the local river (2%). The use of personal protection equipment is well established. Occupational risk assessment showed that the re-entry worker is exposed to a high risk.

CONCLUSION

While a general awareness of the hazard of pesticides to human health and the environment is present, practical implementation of this awareness, however, is still limited in strawberry and chrysanthemum crop. The environmental risk evaluation indicated plant protection products of which the use should be limited.
