Agriculture and musculoskeletal disorders in low- and middle-income countries.

OBJECTIVES: To systematically explore and summarize the risk factors of work-related musculoskeletal disorders (WMSDs) among the agricultural workers in low- and middle-income countries (LMIC). In addition, to identify and analyze the methodological flaws in the reviewed studies. METHODS: A comprehensive electronic literature search was conducted using PubMed, Medline, SCOPUS, CINAHL, Science Direct, Embase, Wiley Online Library, Google Scholar, and Web of Science databases. Three-phased screening process was undertaken to eliminate irrelevant publications. Assessment of methodological quality was done using a standardized assessment tool. RESULTS: Eighteen cross-sectional studies were included in the narrative synthesis. Based on the median score of 38%, nine publications were classified as having higher methodological quality. Eight countries were represented in this review, mainly the South East Asia countries. Majority of the participants were rice farmers. Most common risk factors associated with WMSDs were physical factors (n = 10), followed by individual (n = 6) and psychosocial (n = 5) risk factors. A majority of the studies investigated the risk factors for spinal region. Several methodological weaknesses were noticed in the studies concerning outcome definition, assessment of potential confounders, generalizability, selection bias, information bias, and statistical analysis. Extensive heterogeneity across the studies prevented statistical pooling. CONCLUSIONS: The common anatomical region evaluated was the spine and the most reported risk factors were physical risk factors. Future researches in the LMIC should focus on conducting longitudinal studies that could infer temporality. Researchers should give more attention in defining the study population, evaluating the exposure and outcome in an unbiased way, and in executing reliable statistical analysis.

Farm operators' experiences of advanced technology and automation in Swedish agriculture: a pilot study.

This pilot study investigated how farm operators use and experience working with advanced farm technology and automated systems. The study participants included 10 farm operators at 4 modern and technically well-equipped arable and dairy farms. The informants reported that the technology allowed for more accuracy and efficiency in daily work, made the work less physically strenuous, and gave more time for leisure. The challenges lay in systems and programs not being compatible and difficulties in interpreting generated data. At times, the technology was considered complex or difficult to handle and operate. It was also considered mentally stressful when it did not work as expected. Nightly alarms causing disturbed sleep and work time, and tasks losing some of their clear and natural starts and ends were the most challenging issues on dairy farms. Malfunctions disturbed the daily work, especially when spare parts or service technicians were unavailable. The informants concluded that advanced farm technology and automated systems had both positive and negative sides. They reported no consistent mental strain caused by the technology and considered it a necessity for their future work. However, technology and automated systems must be functional, user-friendly, and reliable to avoid imposing potential mental strain.

Job Resources and Work Engagement among Finnish Dairy Farmers.

OBJECTIVES: The aims of this study were to examine job resources, work engagement and Finnish dairy farmers' preferences concerning methods to enhance overall well-being while working on farms. METHODS: A postal survey yielded 265 completed questionnaires from 188 dairy farms. The sample was assessed as representative of Finnish dairy farmers. Exploratory factor analysis and a linear mixed model were utilized during the data analyzing process. RESULTS: The variables lowering work engagement were stressors related to the workload and problems with health. Elevated work engagement was associated with the factors work with farm animals and family. The most important resource variables were "child or children," "own family," and "animal health." Female dairy farmers considered resource variables related to the family, love, and work with cattle as significantly more important than male dairy farmers. Male dairy farmers experienced higher work engagement and, concerning the dimensions, especially higher dedication and absorption than male respondents in a reference sample of workers in difference occupations. A sustainable farm economy and the possibility to have a holiday period were the most important methods to improve overall well-being on dairy farms. CONCLUSION: The results indicate that the family, working with cattle, healthy farm animals, a reasonable workload, and a sustainable farm economy have the capacity to create positive impacts on well-being among dairy farmers. Well-being on farms is a part of sustainable food production.

Awareness and Need for Knowledge of Health and Safety among Dairy Farmers Interviewed in Uganda.

INTRODUCTION: Safe working conditions are essential for healthy living and for ensuring food security among farmers and farm communities in developing countries. There is limited research on this topic, and documentation is essential to understand and change patterns of human health and safety. METHODS: In May 2014, six male and female farmers on four dairy farms in Uganda and a female veterinarian were interviewed about their awareness and attitudes to agricultural risk factors, health, and safety. In addition, transect walks were conducted on the four dairy farms. RESULTS: The dairy farmers reported health and safety concerns, e.g., diarrhea, coughs, fever, cuts while using machetes in plantations, bruises when handling animals, and dizziness and poisoning symptoms from using different agrochemicals, and considered these an occupational hazard. The most important topic mentioned was the use of agrochemicals and drugs on livestock. The farmers spray their animals with insecticides to prevent ticks, lice, tsetse flies, and other biting nuisance flies, using a backpack or hand sprayer. Spraying is conducted without personal protection equipment, which is considered too expensive and difficult to obtain. The farmers reported that they usually feel dizzy, vomit, and have pain and a burning feeling in their face and eyes after spraying. The symptoms are sometimes so severe that they require treatment. In such cases, the farmers buy medication without a prescription at the local drugstore, where the storekeeper often has limited or no knowledge of agrochemicals or drugs except for dosage. Agricultural health and safety training in the region is non-existent, and the farmers expressed a need and desire for improvements in this area. CONCLUSION: The level of knowledge and awareness of agricultural health and safety risks, disease, and injury prevention among the Ugandan dairy farmers interviewed was low. The farmers mentioned few agriculture-related complaints, injuries, or diseases except poisoning from using agrochemicals. Training on health and safety in Ugandan agriculture is urgently needed.

Occupational Health and Safety of Finnish Dairy Farmers Using Automatic Milking Systems.

INTRODUCTION: Conventional pipeline and parlor milking expose dairy farmers and workers to adverse health outcomes. In recent years, automatic milking systems (AMS) have gained much popularity in Finland, but the changes in working conditions when changing to AMS are not well known. The aim of this study was to investigate the occupational health and safety risks in using AMS, compared to conventional milking systems (CMS). METHODS: An anonymous online survey was sent to each Finnish dairy farm with an AMS in 2014. Only those dairy farmers with prior work experience in CMS were included in the final analysis consisting of frequency distributions and descriptive statistics. RESULTS: We received 228 usable responses (131 male and 97 female; 25.2% response rate). The majority of the participants found that AMS had brought flexibility to the organization of farm work, and it had increased leisure time, quality of life, productivity of dairy work, and the attractiveness of dairy farming among the younger generation. In addition, AMS reduced the perceived physical strain on the musculoskeletal system as well as the risk of occupational injuries and diseases, compared to CMS. However, working in close proximity to the cattle, particularly training of heifers to use the AMS, was regarded as a high-risk work task. In addition, the daily cleaning of the AMS and manual handling of rejected milk were regarded as physically demanding. The majority of the participants stated that mental stress caused by the monotonous, repetitive, paced, and hurried work had declined after changing to AMS. However, many indicated increased mental stress because of the demanding management of the AMS. Nightly alarms caused by the AMS, lack of adequately skilled hired labor or farm relief workers, and the 24/7 standby for the AMS were issues that also caused mental stress. CONCLUSION: Based on this study, AMS may have significant potential in the prevention of adverse health outcomes in milking of dairy cows. In addition, AMS may improve the productivity of dairy work and sustainability of dairy production. However, certain characteristics of the AMS require further attention with regard to occupational health and safety risks.

Epidemiology of Musculoskeletal Symptoms Among Milkers and Dairy Farm Characteristics in Sweden and Germany.

International studies have shown that musculoskeletal symptoms (MSS) and disorders (MSD) are common among dairy farm milkers. Although dairy production is diverse, it has so far not been possible to explain the high risk by production parameters. Two national studies carried out under similar conditions were the incentive to merge the data and increase the sample size. The Standardized Nordic Questionnaire was used to assess MSS prevalence among 92 Swedish and 116 German male and female milkers. Eighty-four percent and 85% of the Swedish and German milkers reported MSS in at least one body part. Highest prevalence was reported in the lower back, shoulder, and neck. Females showed a significantly higher risk of MSS. Apart from that, small significant influence of MSS was found for other risk factors. These findings indicate that technical and organizational modifications of the work place design in milking parlors are needed.

The dairy industry: a brief description of production practices, trends, and farm characteristics around the world.

The global dairy industry is composed of a multitude of countries with unique production practices and consumer markets. The global average number of cows per farm is about 1-2 cows; however, as a farm business model transitions from sustenance to market production, the average herd size, and subsequent labor force increases. Dairy production is unique as an agricultural commodity because milk is produced daily, for 365 days per year. With the introduction of new technology such as the milking parlor, the global industry trend is one of increasing farm sizes. The farm sizes are the largest in the United States; however, the European Union produces the most milk compared with other global producers. Dairy production is essential for economic development and sustainable communities in rural areas. However, the required capital investment and availability of local markets and labor are continued challenges. Due to farm expansion, international producers are faced with new challenges related to assuring food safety and a safe working environment for their workforce. These challenges exist in addition to the cultural and language barriers related to an increasing dependence on immigrant labor in many regions of the world. Continued success of the global dairy industry is vital. Therefore, research should continue to address the identification of occupational risk factors associated with injuries and illnesses, as well as develop cost-effective interventions and practices that lead to the minimization or elimination of these injuries and illnesses on a global scale, among our valuable population of dairy producers and workers.

Ergonomics in modern dairy practice: a review of current issues and research needs.

Dairy farming is an ancient occupation. Traditionally, cows have been manually milked while tethered in stalls or stanchions. In the latter half of the 20th century as machine milking emerged, the parlor milking system has become more popular, especially among larger dairy farms. The transition from manual milking to automatic milking systems as well as the transition from stanchion to parlor milking systems involved a dramatic change in milking tasks. These transitions have resulted in changing patterns of occupational exposure to risk factors for work-related musculoskeletal disorders among dairy workers. However, aspects of the milking task such as sanitization of teats, stripping milk from teats, and attachment and detachment of milking equipment have remained relatively the same. Work-related musculoskeletal symptoms have been reported in the low back, shoulders, hands/wrists, and knees. Research that has measured exposures to risk factors for work-related musculoskeletal disorders among dairy farm workers has been limited, especially when using ergonomic tools to directly measure exposure, such as electrogoniometry or electromyography. Self-reported exposure measures have been most commonly used. The interventions that have been tested to reduce exposure to risk factors for work-related musculoskeletal disorders include assisted lift-hold devices, use of lighter-weight equipment, adjustable flooring, and use of rubber mats. However, research evaluating potential solutions to reduce dairy farm worker exposure to risk factors for musculoskeletal disorders is scarce. Future research efforts should further characterize hazards while simultaneously testing viable solutions that fit within the business model of the dairy farm industry.

Work-related injuries and fatalities on dairy farm operations-a global perspective.

Agriculture is among the most hazardous sectors for workers globally, and dairy farming has been associated with a high risk of injury among workers in several countries. The purpose of this paper is to provide an update on what is known about modern dairy farms and related injuries and fatalities in different regions of the world. As in other sectors of agriculture, fatalities appear to be associated with heavy equipment usage, whereas injuries occur at higher rates with animal production, specifically cattle and milk production. Dairy farming is associated with higher rates of injury as compared with other industrial sectors, but a lack of work-related injury reporting continues to be an issue in several countries. Worker fatality associated with heavy equipment use is not a new observation (e.g., tractors); however, manure-handling systems, livestock handling, and quad bike operation continue to be associated with worker injuries and fatalities on modern farms. Opportunities exist for improvement of safety-related equipment to reduce injury and fatality risk during worker interactions with large animals and farm equipment.

International perspectives on psychosocial working conditions, mental health, and stress of dairy farm operators.

Dairy farm operators-farmers, workers, and family members-are faced with many demands and stressors in their daily work and these appear to be shared across countries and cultures. Dairy operators experience high psychosocial demands with respect to a hard work and production ethos, economic influences, and social and environmental responsibility. Furthermore, both traditional and industrial farms are highly dependent on external conditions, such as weather, fluctuating markets, and regulations from government authorities. Possible external stressors include disease outbreaks, taxes related to dairy production, and recent negative societal attitudes to farming in general. Dairy farm operators may have very few or no opportunities to influence and control these external conditions, demands, and expectations. High work demands and expectations coupled with low control and lack of social support can lead to a poor psychosocial work environment, with increased stress levels, ill mental health, depression, and, in the worst cases, suicide. Internationally, farmers with ill mental health have different health service options depending on their location. Regardless of location, it is initially the responsibility of the individual farmer and farm family to handle mental health and stress, which can be of short- or long-term duration. This paper reviews the literature on the topics of psychosocial working conditions, mental health, stress, depression, and suicide among dairy farm operators, farm workers, and farm family members in an international perspective.

Occupational health and safety aspects of animal handling in dairy production.

Livestock handling in dairy production is associated with a number of health and safety issues. A large number of fatal and nonfatal injuries still occur when handling livestock. The many animal handling tasks on a dairy farm include moving cattle between different locations, vaccination, administration of medication, hoof care, artificial insemination, ear tagging, milking, and loading onto trucks. There are particular problems with bulls, which continue to cause considerable numbers of injuries and fatalities in dairy production. In order to reduce the number of injuries during animal handling on dairy farms, it is important to understand the key factors in human-animal interactions. These include handler attitudes and behavior, animal behavior, and fear in cows. Care when in close proximity to the animal is the key for safe handling, including knowledge of the flight zone, and use of the right types of tools and suitable restraint equipment. Thus, in order to create safe working conditions during livestock handling, it is important to provide handlers with adequate training and to establish sound safety management procedures on the farm.
