Moral distress measurement in animal care workers: a systematic review

ObjectivesThe mental health of veterinary and other animal health professionals is significantly impacted by the psychological stressors they encounter, such as euthanasia, witnessing animal suffering and moral distress. Moral distress,...

Zoonotic and Zooanthroponotic Potential of Monkeypox.

The current multicounty outbreak of monkeypox virus (MPXV) posed an emerging and continued challenge to already strained public healthcare sector, around the globe. Since its first identification, monkeypox disease (mpox) remained enzootic in Central and West African countries where reports of human cases are sporadically described. Recent trends in mpox spread outside the Africa have highlighted increased incidence of spillover of the MPXV from animal to humans. While nature of established animal reservoirs remained undefined, several small mammals including rodents, carnivores, lagomorphs, insectivores, non-human primates, domestic/farm animals, and several species of wildlife are proposed to be carrier of the MPXV infection. There are established records of animal-to-human (zoonotic) spread of MPXV through close interaction of humans with animals by eating bushmeat, contracting bodily fluids or trading possibly infected animals. In contrast, there are reports and increasing possibilities of human-to-animal (zooanthroponotic) spread of the MPXV through petting and close interaction with pet owners and animal care workers. We describe here the rationales and molecular factors which predispose the spread of MPXV not only amongst humans but also from animals to humans. A range of continuing opportunities for the spread and evolution of MPXV are discussed to consider risks beyond the currently identified groups. With the possibility of MPXV establishing itself in animal reservoirs, continued and broad surveillance, investigation into unconventional transmissions, and exploration of spillover events are warranted.

“A Love–Hate Relationship with What I Do”: Protecting the Mental Health of Animal Care Workers

ABSTRACT Mental ill-health associated with animal care work, coupled with a current shortage of animal care workers (ACWs), highlights the need to support this population’s wellbeing. Guided by the Job Demands-Resources model of burnout and the principles of positive occupational health psychology, we aimed to explore mental ill-health in ACWs and identify potential risks and protective factors for their wellbeing. ACWs (n = 217) completed an anonymous online questionnaire with measures of post-traumatic stress disorder (PTSD) symptoms, psychological distress, burnout, grief, social support, organizational support, and empathy for animals. We also asked an open question about what participants liked about their work. Our sample had a higher incidence of mental ill-health than the Australian general population. Multiple regression analyses suggested grief may be a job demand for ACWs, significantly accounting for 2.8–4.3% of the variance in burnout. Likewise, organizational support may be a job resource for ACWs, significantly accounting for 17.3–25.5% of the variance in burnout. Finally, qualitative content analysis indicated that ACWs enjoyed professional accomplishments, interpersonal interactions, and contact with animals as part of their work. We discuss our results and how they may be used to inform the implementation of workplace changes that support ACWs’ wellbeing.

A Preliminary Assessment of Compassion Fatigue in Chimpanzee Caregivers.

Compassion fatigue is defined as "traumatization of helpers through their efforts at helping others". It has negative effects on clinicians including reduced satisfaction with work, fatigue, irritability, dread of going to work, and lack of joy in life. It is correlated with patients' decreased satisfaction with care. Compassion fatigue occurs in a variety of helping professions including educators, social workers, mental health clinicians, and it also appears in nonhuman animal care workers. This study surveyed caregivers of chimpanzees using the ProQOL-V to assess the prevalence of compassion fatigue among this group. Compassion satisfaction is higher than many other types of animal care workers. Conversely, this group shows moderate levels of burnout and secondary traumatic stress; higher levels than other types of animal care workers and many medical professions. While compassion fatigue has an effect on the caregiver's experience, it has potential to affect animal welfare. Caregivers are an integral part of the chimpanzee social network. Compassion fatigue affects the caregiver's attitude, this could in turn affect the relationship and degrade the experience of care for captive chimpanzees. Compassion fatigue can be mitigated with professional development, mindfulness training, interrelationships among staff, and specialized training. This preliminary assessment indicates the work ahead is educating caregivers about compassion fatigue and implementing procedures in sanctuaries to mitigate burnout and secondary traumatic stress.

COVID-19 Pandemic Response Preparedness and Risk Perceptions Among Peruvian Veterinarians and Animal Care Workers.

Peruvian veterinarians and animal care workers (VACW) are primary responders in the event of disasters or emergencies, yet they face unique concerns that could impede or block their essential functions in public health preparedness in comparison with VACWs in other countries. In this study, we used the Ready, Willing, and Able model via electronic survey to evaluate the perception of risks and barriers that Peruvian VACWs faced when deciding whether to continue working during the COVID-19 pandemic between July and December 2020. We used logistic regression models to evaluate associations between demographic characteristics, perceived role, and contact scores with 8 outcomes: knowledge of COVID-19; confidence in safety protocols; perceived threat; perceived job efficacy; perceived barriers; and readiness, willingness, and ability to respond to the COVID-19 pandemic. Less than 50% of respondents reported barriers to report to work during the pandemic. Respondents who reported higher contact with coworkers had an increased confidence in safety protocols (OR 5.16; 95% CI, 1.36 to 19.61) and willingness (OR 3.76; 95% CI, 1.14 to 12.47) to respond to the pandemic. Close contacts with essential workers and higher economic income were associated with higher reported knowledge of COVID-19. Respondents with higher perceived job efficacy had higher odds of reporting being ready, willing, and able to respond to COVID-19, while those who identified more barriers to report to work had lower odds of being ready, willing, and able to respond. The findings from this study, which showed differences from VACWs in the United States, can be used by individuals designing programs to improve pandemic and disaster preparedness in this essential, yet understudied and vulnerable, workforce.

Identification and Control of an Ornithonyssus Bacoti Infestation in a Rodent Vivarium by Using Molecular Diagnostic Techniques.

Ornithonyssus bacoti, commonly known as the tropical rat mite, is a zoonotic ectoparasite that occasionally infests research rodent colonies. Most infestations have been attributed to wild rodents that harbor the mite and spread it to research animals, often during building construction or other activity that disrupts wild rodent populations. Although infestation may be clinically silent, severe outbreaks have been reported to cause pruritis, dermatitis, decreased reproductive performance, and anemia in rodents. In mid-2020, our institution experienced increased activity of wild mice, which were found to be infested with O. bacoti, diagnosed by microscopic exam and confirmed by fur swab PCR analysis. We elected to add O. bacoti to our quarterly health monitoring exhaust air dust (EAD) testing PCR panel, increase wild mouse control measures, and treat the environment with a sustained-release synthetic pyrethroid spray in an attempt to prevent colony animal infestation. Initial quarterly EAD health monitoring results in September of 2020 were negative for O. bacoti. However, in early 2021, multiple IVC racks tested positive for O. bacoti at quarterly testing. Treatment consisted of providing permethrin-soaked nesting material and surface spray treatment of the room and hallway with a sustained-release synthetic pyrethroid. Historically in the literature, O. bacoti outbreaks of research mice were not identified until mite burden was high enough to cause dermatitis on animal care workers. Due to modern molecular diagnostics and proactive PCR-based health monitoring surveillance, we were able to identify the outbreak earlier than would have otherwise been possible. To the best of our knowledge, this is the first report to successfully identify O. bacoti using environmental health monitoring PCR techniques. This outbreak demonstrates the importance of screening for O. bacoti in facilities with the potential for wild rodent infestation and highlights unique considerations when managing O. bacoti infestations. In addition, a novel permethrin-soaked enrichment item was developed for cage-level treatment.

Assessing COVID-19 Pandemic Risk Perception and Response Preparedness in Veterinary and Animal Care Workers.

Veterinary and animal care workers perform critical functions in biosecurity and public health, yet little has been done to understand the unique needs and barriers these workers face when responding during a pandemic crisis. In this article, we evaluated the perceived risks and roles of veterinary and animal care workers during the COVID-19 pandemic and explored barriers and facilitators in their readiness, ability, and willingness to respond during a pandemic. We deployed a survey targeting US veterinary medical personnel, animal shelter and control workers, zoo and wildlife workers, and other animal care workers. Data were collected on respondents' self-reported job and demographic factors, perceptions of risk and job efficacy, and readiness, ability, and willingness to respond during the pandemic. We found that leadership roles and older age had the strongest association with decreased perceived risk and improved job efficacy and confidence, and that increased reported contact level with others (both coworkers and the public) was associated with increased perceived risk. We determined that older age and serving in leadership positions were associated with improved readiness, willingness, and ability to respond. Veterinary and animal care workers' dedication to public health response, reflected in our findings, will be imperative if more zoonotic vectors of SARS-CoV-2 arise. Response preparedness in veterinary and animal care workers can be improved by targeting younger workers not in leadership roles through support programs that focus on improving job efficacy and confidence in safety protocols. These findings can be used to target intervention and training efforts to support the most vulnerable within this critical, yet often overlooked, workforce.

Investigating the presence of human anti-mouse antibodies (HAMA) in the blood of laboratory animal care workers

Abstract Background In the present study, the researchers evaluated the presence of human anti-mouse antibodies (HAMA) in a normal population and laboratory animal care providers for the first time in the world. Also, the cause of HAMA incidence in the human body through a close contact with mice was identified. Methods The study population consisted of 40 laboratory animal care providers aged between 24 and 57 years with a close contact with mice (e.g. taking care of mice, feeding mice, etc.) and 40 individuals of the same age as the above group with no contact with mice. HAMA was measured in both the case and control groups using sandwich enzyme-linked immunosorbent assay (ELISA) method. Data were analyzed using SPSS 18. Univariate and multivariate linear regression and independent t-test were used. The significance of results was measured based on p < 0.05. Results The present study revealed that the animal care providers had (p = 000) a higher titer of HAMA (4.95 ng/mL) in their blood than the control group (1.67 ng/mL). Also, the individuals in the case group (exposed to mice) were more allergic (43.6%) than those in the control group (15%) (p = 0.003). Conclusions The results of this study revealed that exposure to mice in laboratory care centers can cause production of HAMA in the human body but its titer is possibly lower in Iranian working staff than those in the other parts of the world.

Exploring the loss and disenfranchised grief of animal care workers

This article explores the psychological distress of Animal Care Workers (ACWs), and the disenfranchisement of this distress through mixed methods study conducted as an online survey. In all, 139 participants responded about their experiences as an ACW, related psychological distress, and the systemic disenfranchisement of distress. Findings indicate that nearly half of ACWs experienced symptoms of depression in the previous month. Over 66% indicated it was difficult to cope. Limited support often resulted in a disenfranchized loss. Implications suggest ACW distress and disenfranchisement related to animals they serve is similar to that of individuals who lose animal companions.

Rabies exposures and pre-exposure vaccination practices among individuals with an increased risk of rabies exposure in the United States.

OBJECTIVE To identify knowledge and practices related to rabies vaccination and serologic monitoring among animal care workers in the United States. DESIGN Cross-sectional survey. SAMPLE 2,334 animal care workers (ie, veterinarians, veterinary technicians, animal control workers, and wildlife rehabilitators). PROCEDURES Participants were contacted through relevant professional organizations to participate in an anonymous web-based survey. The survey collected demographic and occupational information, animal handling and potential rabies exposure information, and individual rabies vaccination and serologic monitoring practices. Comparisons of animal bite and rabies exposure rates were made between occupational groups. Multiple logistic regression was used to evaluate factors associated with rabies vaccination status and adherence to serologic monitoring recommendations. RESULTS Respondents reported 0.77 animal bites/person-year or 0.10 bites/1,000 animals handled. The overall rate of postexposure prophylaxis due to an occupational rabies exposure was 1.07/100 person-years. Veterinarians reported the highest rabies vaccination rate (98.7% [367/372]), followed by animal control workers (78.5% [344/438]), wildlife rehabilitators (78.2% [122/156]), and veterinary technicians (69.3% [937/1,352]). Respondents working for employers requiring rabies vaccination and serologic monitoring were 32.16 and 6.14 times, respectively, as likely to be vaccinated or have a current serologic monitoring status as were respondents working for employers without such policies. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that, given the high reported rates of animal bites and potential rabies exposures among animal care workers, improvements in rabies vaccination and serologic monitoring practices are needed.

Biomarkers of respiratory allergy in laboratory animal care workers: an observational study.

Laboratory animal allergy is a highly prevalent occupational disease among exposed workers. The aim of the study was to validate the biomarkers of airway inflammation in laboratory animal (LA) care workers. All of the participants in this observational study (63 LA care workers and 64 controls) were administered a clinical questionnaire, underwent spirometry and a skin prick or radioallergosorbent test for common and occupational aeroallergens, and the fraction of exhaled nitric oxide (FeNO50), exhaled breath condensate hydrogen peroxide (EBC H2O2) and serum pneumoprotein levels were measured. Multivariate analysis (ANCOVA) was used to assess the interactions of the variables. FeNO50 levels correlated with exposure (p = 0.002), sensitisation (p = 0.000) and age (p = 0.001), but there was no interaction between exposure and sensitisation when age was considered in the model (p = 0.146). EBC-H2O2 levels were higher in the sensitised workers than in the sensitised controls [0.14 (0.08-0.29) µM vs 0.07 (0.05-0.12) µM; p < 0.05]. Serum surfactant protein A (SP-A) levels were unaffected by exposure, sensitisation or age, although higher levels were observed in symptomatic workers; however, SP-D levels were influenced by exposure (p = 0.024) and age (p = 0.022), and club cell 16 levels were influenced by sensitisation (p = 0.027) and age (p = 0.019). The presence of the clinical symptoms associated with LA exposure and high FeNO levels should prompt further medical assessments in LA workers. Although EBC-H2O2 levels do not seem to reflect eosinophilic inflammation, serum SP-A levels could be used to monitor progression from rhinitis to asthma.

BIOAEROSOL INVESTIGATION IN THREE VETERINARY TEACHING HOSPITALS IN TAIWAN

Veterinary staff could be in frequent exposure to a variety of physical, chemical and biological hazards. Epidemiologic studies have showed that veterinarians are at increased risk of many occupational illnesses such as dermatoses, respiratory tract illnesses, zoonotic infections, acute pesticide-associated toxicity, fetal loss and site-specific cancers. Most biological hazards are distributed in the form of aerosols in the workplaces. This study intended to investigate the potential occupational hazards faced by veterinarians in small-animal practices through field sampling for microbial pathogens in their working environment. Sampling of bacterial and fungal bioaerosols was carried out using an SKCⓇstandard biostage impactor at an air-flow rate of 28.3[Formula: see text]L[Formula: see text]min[Formula: see text] by a vacuum pump through 400 (0.25-mm) holes for 30[Formula: see text]s. Identification of microbial organisms was carried out by DNA extraction and sequencing for 16S and 18S ribosomal DNA of bacteria and fungi. The results showed the bacteria that occurred most frequently in the sampled hospitals were Micrococcus spp. and Staphylococcus spp., and the fungi were Coriolopsis spp. and Microporus spp. Although some of these microbiota were zoonotic, there were no virulent pathogens identified. Our results revealed the possible biological risks for the veterinary workers in small animal hospitals in Taiwan. Proper disinfection and sterilization procedures in workplaces with health education to the animal care workers shall protect them from the occupational injuries.

Olfaction variation in mouse husbandry and its implications for refinement and standardization: UK survey of animal scents.

Olfaction plays a crucial role in mouse communication, providing information about genetic identity, physiological status of conspecifics and alerting mice to potential predators. Scents of animal origin can trigger physiological and behavioural responses that could affect experimental responses and impact positively or negatively on mouse welfare. Additionally, differing olfactory profiles could help explain variation in results between laboratories. A survey was sent to animal research units in the UK to investigate potential transfer of scents of animal origin during routine husbandry procedures, and responses were obtained from animal care workers and researchers using mice in 51 institutions. The results reveal great diversity between animal units regarding the relevant husbandry routines covered. Most [71%] reported housing non-breeding male and female mice in the same room, with 76% reporting that hands were not washed and gloves not changed between handling male and female mice. The most commonly reported species housed in the same facility as mice was the rat (91%), and 41% of respondents were aware that scents from rats could affect mice. Changing of gloves between handling mice and other species was reported by 79% of respondents. Depending on the aspect considered, between 18 and 33% of respondents believed human and non-human animal odours would strongly affect mouse physiology, behaviour or standardization, while approximately 32-54% believed these effects would be weak. This indicates uncertainty regarding the significance of these factors. Understanding and controlling these practices could reduce unwanted variability in experimental results and maximize welfare.

Work-related injuries to animal care workers, Washington 2007-2011.

For workers engaged in animal care, workplace hazards are common and may outnumber those experienced by human healthcare workers. We used accepted Washington State workers' compensation claims for the period from January 1, 2007 and December 31, 2011 to compare injury rates and types of injuries across animal care occupations. Work-related injuries frequently affect veterinary support staff and those working in pet stores, shelters, grooming facilities and kennels. Animal-related injuries were the most commonly reported injury type experienced by all groups, though the animal source of injury appears to differ by work setting. Workplace related injuries among animal care workers are common and most often caused by physical insults resulting from worker-animal interaction.

Normal Blood Parameters, Common Diseases and Parasites Affecting Captive Non-human Primates

Non-human primates are kept in captivity as zoological exhibits as well as being used for research purposes and as breeding colonies of endangered species with the aim of eventual release back into the wild. The aim of this review is to collate data obtained for blood parameters for healthy animals as well as common diseases and parasites encountered in captive non-human primates. This information can be used as a reference for veterinarians, researchers and animal care workers working with primates. Comparisons to wild primates are made where appropriate.

Bilingual, Digital, Audio-Visual Training Modules Improve Technical Knowledge of Feedlot and Dairy Workers

Two studies were conducted to determine the effectiveness of digital multimedia modules as training tools for animal care workers. Employees at a commercial feedlot (n = 17) and a commercial dairy (n = 10) were asked to independently complete a 10-question quiz prior to and following viewing of training modules. Module topics in the feedlot were proper handling of non-ambulatory animals and humane methods of euthanasia; modules were administered to the workers, as a group, in either English (n = 7) or Spanish (N = 10), depending on previously indicated worker preference. Modules addressing dairy cattle health practices and dairy cattle handling were presented to the dairy care workers who had a preference for learning in either English (n = 7) or Spanish (n = 3). For feedlot workers, post-test scores were improved by 28% after viewing the modules compared to pre-test scores (74% vs. 58%; P < 0.01), across language and topic. There were no interactions (P > 0.30) between language, topic, and between-test variation, indicating that the modules were equally effective at information delivery to both audiences in both languages. For the dairy workers, test scores improved by 27% from pre-viewing to post-viewing (73% vs. 92%; P < 0.01); there was an interaction between the effect of module and language preference (P < 0.01) indicating that although scores increased for both of the topic areas for the English-speaking workers, only the score for the animal health topic increased for the Spanish-speaking workers. Regardless of nationality, level of formal education, topic, or preferred language, digital media are effective at improving knowledge transfer to animal care professionals.

Inactivation of bacteria and viruses in water: passage of germicidal ultraviolet light through Teflon.

Teflon pipe as used in a water purification system transmitted germicidal ultraviolet (UV) light to inactivate Pseudomonas aeruginosa and poliovirus. The information is useful for animal care workers and others concerned with the prevention of microbial growth in water systems such as deionizers and distilled water. Of special significance is that there is a plastic that transmits UV light.
