Occupational Health and Safety Aspects of Animal Handling in Dairy Production

Human–Animal Interactions with Bos taurus Cattle and Their Impacts on On-Farm Safety: A Systematic Review

Cattle production necessitates potentially dangerous human–animal interactions. Cattle are physically strong, large animals that can inflict injuries on humans accidentally or through aggressive behaviour. This study provides a systematic review of literature relating to farm management practices (including humans involved, facilities, and the individual animal) associated with cattle temperament and human’s on-farm safety. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) was used to frame the review. Population, Exposure, and Outcomes (PEO) components of the research question are defined as “Bovine” (population), “Handling” (exposure), and outcomes of “Behaviour”, and “Safety”. The review included 17 papers and identified six main themes: actions of humans; human demographics, attitude, and experience; facilities and the environment; the animal involved; under-reporting and poor records; and mitigation of dangerous interactions. Cattle-related incidents were found to be underreported, with contradictory advice to prevent injury. The introduction of standardised reporting and recording of incidents to clearly identify the behaviours and facilities which increase injuries could inform policy to reduce injuries. Global differences in management systems and animal types mean that it would be impractical to impose global methods of best practice to reduce the chance of injury. Thus, any recommendations should be regionally specific, easily accessible, and practicable.

Promoting farming sustainability: The effects of age, training, history of accidents and social-psychological variables on the adoption of on-farm safety behaviors

INTRODUCTION

Occupational safety and health (OSH) have a remarkable impact on the sustainability of firms and organizations. However, the sustainability perspective has often focused primarily on environmental and economic concerns, leaving key social and workplace aspects, such as OSH, underemphasized. The link between all these aspects is particularly relevant in agriculture.

METHOD

In the present study we analyzed the paths by which the worker's age, participation in safety training, and previous history of accidents and near misses can influence the adoption of safety behaviors in agriculture through the mediation of attitudes towards safety and perceived behavioral control. Three hundred and ten Italian agricultural operators were administered an ad-hoc questionnaire.

RESULTS

Having attended safety training courses, having been exposed to previous accidents and near misses, and age showed a positive association with the adoption of on-farm safety behaviors, through the mediation of perceived behavioral control. In more detail, participation in training courses and age showed a positive association with perceived behavioral control, while the previous history of accidents and near misses showed a negative association with behavioral control. In turn, perceived behavioral control was positively associated with the adoption of safety behaviors.

CONCLUSIONS

The present study focused on the chain of events leading to the adoption of on-farm safety behaviors, which can prevent an accidents, pointing out the more critical variables and the level at which they intervene, identifying possible areas of targeted interventions. Practical applications: Implications for the development of targeted interventions may deal with: (a) training activities increasing farm operators' sense of control over their safety, (b) older farmers involvement in mentoring initiatives, and (c) systematic recording and use of previous history of accidents and near misses as inputs for training activities to discuss their implications for on-farm safety.

Review: From human-animal relation practice research to the development of the livestock farmer's activity: an ergonomics-applied ethology interaction

Animal husbandry and working conditions for livestock farmers have changed significantly in recent years as agriculture has been exposed to economic as well as health, environmental and ethical challenges. The idea of interdependent welfare between humans and animals is more relevant now than ever. Here, we innovatively bridge two disciplines-ergonomics and applied ethology-to achieve an in-depth observational understanding of real husbandry practice (by farmers, inseminators, vets) at work. Ergonomics aims to gain a detailed understanding of human activity in its physical, sensitive and cognitive dimensions in relation to a task. It also aims to transform work situations through a systemic approach drawing on multiple levers for change. Here, we examine how this analysis holds up to the inclusion of animals as an integral component of the livestock farmer's work situation. Applied ethology studies behaviours in animals managed by humans. It aims to understand how these animals perceive their environment, including how they construct their relationship with the livestock farmer. This paper proposes an original conception of the human-animal relationship in animal husbandry that employs core structural concepts from both disciplines. From an ergonomic point of view, we address the human-animal relations by examining the relationship between 'prescribed' and real work practices, between work and personal life situation, between professional task and human activity. On the applied ethology side of the equation, the human-animal relationship is a process built through communication and regular interactions between two 'partners' who know each other. The goal is to understand how each partner perceives the other according to their multimodal sensory world and their cognitive and emotional capacities, and to predict the outcome of future interactions. We cross-analyse these scientific views to show, based on examples, how and in what way they can intersect to bring better analysis of these human-animal relationships. We reflect on common working hypotheses and situated observational approaches based on indicators (behaviour and animal and human welfare/health). This analysis prompts us to clarify what human-animal relational practice means in animal husbandry work, i.e. a strategy employed by the livestock farmer to work safely and efficiently in a healthy environment, where the animal is treated as a partner in the relationship. In this perspective, the challenge is for the livestock farmer's activity to co-build a positive relationship and avoid being subject to this one.

Transnational health protection strategies and other health-seeking behavior among undocumented and indigenous dairy workers in a rural new immigrant destination

Latin American immigrants in new immigrant destinations (NIDs) experience numerous barriers that negatively impact their access to healthcare. Yet the wide range of health-seeking behaviors deployed in response to these barriers-particularly among those who are undocumented and indigenous-are not well understood. Further, studies of immigrant health in NIDs tend to take place in those locations, rather than using a multi-sited design. Building on NID scholarship, the transnational social protection literature, and work on structural vulnerability, this study uses a multi-sited research design to examine the health-seeking behaviors that undocumented and indigenous immigrant workers exhibit in a rural NID. Data consist of interviews conducted intermittently from 2010 to 2017 in Mexico and the U.S. with 56 individuals from indigenous villages in Veracruz who worked on dairy farms in Wisconsin and Minnesota, as well as expert interviews. We found numerous barriers to healthcare that together constituted a limited resource environment for undocumented dairy workers. This accentuated their structural vulnerability and influenced responses to health problems. Strategies among undocumented and indigenous immigrant dairy workers in a rural NID included: self-care, delaying care, relying on local ties, cross-border health consultation, cross-border health packages, and returning home for health. Furthermore, we found that women in the family or community often facilitated cross-border health activity, and that traditional folk medicine was common. We argue that these workers' health protection strategies not only serve to secure their individual status as productive workers, but on a larger scale, they play an important part in preserving the migrant labor regime in this rural NID. Further, we argue that the indigenous knowledge that is transmitted largely by women via immigrants' informal social networks is an important yet often invisible part of the carework that maintains this relatively new labor force.

Precarious Essential Work, Immigrant Dairy Farmworkers, and Occupational Health Experiences in Vermont

Migrant dairy workers in Vermont face a wide range of occupational and health hazards at work. This research examines the environmental risks, occupational health hazards, and health outcomes experienced by migrant dairy farm workers in Vermont. This research draws on a triangulation of sources including analysis of data—surveys and interviews with migrant dairy farmworkers gathered by the organization Migrant Justice since 2015 as well as relevant key informant interviews with community organizations across the state to characterize the occupational health experiences of migrant dairy workers in Vermont. Our results show that Vermont migrant dairy farmworkers received poor health and safety training and lacked sufficient protective gear. Over three quarters of the respondents reported experiencing harm from chemical and biological risks. Close to half the survey respondents reported headaches, itchy eyes and cough; a quarter reported breathing difficulties; three fourths reported being hurt by animal-related risks. These exposures and existing health concerns are avoidable. Migrant workers require better social representation and advocates to negotiate better work-related protection and training, access to health services, and social welfare to ensure their health and safety.

Preliminary Study Exploring Caretaker Perspectives of Euthanasia on Swine Operations

The purpose of this study was to gain a better understanding of euthanasia training, caretaker perceptions of euthanasia, and available resources for individuals who perform euthanasia as part of their job on swine operations in the United States. An online survey was distributed via an e-newsletter and in-person recruitment at swine industry events. Survey questions were related to training, attitudes towards performing euthanasia, work environment, and communication. Forty-five responses (17 workers, 21 managers, 7 owners) were recorded and summarized. The majority of workers (n = 14, 82%) agreed that they had "received enough training to euthanize pigs correctly" and that training had made them "confident about performing euthanasia", yet 35% (6) also indicated they would like more euthanasia training. Less than one-third of workers indicated that strategies for dealing with "personal stress" (4, 24%) and "emotional wellness" 29% (5) were included in training programs but the majority (14, 82%) agreed that "trainings included human safety while performing euthanasia". Most caretakers (37, 82%) agreed that they felt they could "communicate with my supervisors" if they felt uncomfortable performing euthanasia. Opportunities for the future include enhancing euthanasia training opportunities and content to include more awareness of strategies to deal with stress related to euthanasia.

A Scoping Review of Safety and Health Interventions in the High-Risk Dairy Industry: Gaps in Evidence Point to Future Directions in Research

The occupational injury rate of the dairy industry (6.6 per 100 full-time workers) is twice that of the national average across all industries (3.3 per 100 full-time workers). While dairy farms are becoming larger in size and fewer in number, this rate has not changed. A scoping review was conducted to identify published reports of occupational safety interventions in the dairy industry. An additional criterion was that the study included an evaluation of the intervention. Out of 22 articles that met the first criterion (discussion of interventions specific to the dairy industry), 19 met the second of having an evaluative component. These 19 articles corresponded to 16 unique studies, because 4 articles corresponded to the same study. Of the 16 unique studies, only 3 had a comparison of treatment vs. control effects, and none measured the impact of the intervention on injuries and fatalities. Of the 16 interventions, 6 were focused on training or informational campaigns in which the evaluations primarily measured knowledge acquisition. Additionally, none of these studies had a sufficient sample size to compare injury rates as an outcome. Our study demonstrates that the literature lacks any rigorous evaluation of whether dairy safety interventions are making an impact on injury prevention. Given this, it is not possible to determine how work-related injuries and deaths can be prevented in the dairy industry. Recommendations for future research include incorporating rigorous evaluation into research designs and attempting to develop low-cost, unobtrusive methods for collecting data on intermediate and final outcomes.

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.

An overview and impact assessment of OSHA large dairy local emphasis programs in New York and Wisconsin

BACKGROUND

Farming has been exempted from most labor regulations and shielded from regulatory scrutiny by the Occupational Safety and Health Administration (OSHA). Yet, agriculture and dairy in particular, has relatively high injury and fatality rates.

METHODS

A recent shift in OSHA's approach to agricultural worker safety and health includes two dairy-focused Local Emphasis Programs (LEPs), one launched in Wisconsin in 2011 and the other in New York in 2014. We examine data from LEP-related, OSHA consultations and inspections as well as non-governmental audit programs, and review farmer perceptions about the LEP.

RESULTS

Inspections conducted by OSHA and private consultation programs highlight the presence and variety of hazards on dairy farms in Wisconsin and New York.

CONCLUSION

The LEPs helped raise dairy producers' awareness of inherent hazards and methods to correct them. Farmers cited the LEP as beneficial, identifying it as a catalyst to reduce hazards on their farms.

It does not occur by chance: a mediation model of the influence of workers' characteristics, work environment factors, and near misses on agricultural machinery-related accidents

Agriculture is among the most hazardous productive sectors, and farm machinery is a major source of injury. In the present study, a mediated model was used to test the role played by workers' characteristics, work environment factors, and near misses in predicting agricultural machinery-related accidents in a sample of Italian users (n = 290). Hours worked per week (via the mediation of an adverse work environment) showed a positive association and years of work experience (via the mediation of risk perception) showed a negative association with the probability of being involved in a near miss, which in turn showed a positive association with the probability of being involved in a machinery-related accident. Implications for tailored preventive interventions are discussed.

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.

Willingness to Consult a Veterinarian on Physician's Advice for Zoonotic Diseases: A Formal Role for Veterinarians in Medicine?

Physicians appear to find zoonotic diseases a challenge and consider that this topic belongs more to the veterinary profession. However, veterinarians have no formal role in clinical medicine. Data were collected as part of the Queensland Social Survey 2014 to determine the willingness of the public, if diagnosed with a zoonotic disease, to consult a veterinarian on the advice of a physician. Self-reported willingness to consult with a veterinarian at the respondent’s own expense was 79.8% (95% CI: 81.96%-77.46%) (976/1223). If the cost was funded by Medicare, the Australian public health insurance scheme, 90.7% (95% CI: 92.18%-88.92%) (1109/1223) would be willing to consult a veterinarian. Therefore, a large majority of Australian residents would be willing to consult with a veterinarian on the advice of their physician if they had a zoonotic disease. Does this indicate a possible new role for veterinarians under Clinical One Health?

Dairy cow handling facilities and the perception of Beef Quality Assurance on Colorado dairies

A survey was conducted on Colorado dairies to assess attitudes and practices regarding Dairy Beef Quality Assurance (DBQA). The objectives were to (1) assess the need for a new handling facility that would allow all injections to be administered via DBQA standards; (2) establish if Colorado dairy producers are concerned with DBQA; and (3) assess differences in responses between dairy owners and herdsmen. Of the 95 dairies contacted, 20 (21%) agreed to participate, with a median herd size of 1,178. When asked to rank the following 7 traits--efficiency, animal safety, human safety, ease of animal handling, ease of operation, inject per Beef Quality Assurance (BQA) procedures, and cost--in order of priority when designing a new handling facility, human and animal safety were ranked highest in priority (first or second) by the majority of participants, with ease of animal handling and efficiency ranked next. Interestingly, the administration of injections per BQA standards was ranked sixth or seventh by most participants. Respondents estimated the average annual income from the sale of cull cows to be 4.6% of all dairy income, with 50% receiving at least one carcass discount or condemnation in the past 12 mo. Although almost all of the participating dairy farmers stated that the preferred injection site for medications was the neck region, a significant number admitted to using alternate injection sites. In contrast, no difference was found between responses regarding the preferred and actual location for intravenous injections. Although most participating producers are aware of BQA injection guidelines, they perceive efficiency as more important, which could result in injections being administered in locations not promoted by BQA. Dairy owners and herdsmen disagreed in whether or not workers had been injured in the animal handling area in the last 12 mo. Handling facilities that allow for an efficient and safe way to administer drugs according to BQA guidelines and educational opportunities that highlight the effect of improved DBQA on profitability could prove useful. Dairy producers play a key role in ensuring that dairy beef is safe and high quality, and just as they are committed to producing safe and nutritious milk for their customers, they should be committed to producing the best quality beef.
