Survey of veterinarians who use pentobarbital for euthanasia suggests knowledge gaps regarding animal disposal.

OBJECTIVE: To assess (1) veterinarians' knowledge and practices regarding disposal of euthanized animals, (2) the extent to which veterinarians communicate with their clients about potential risks of rendering pentobarbital-euthanized animals, and (3) the extent to which veterinarians communicate potential relay toxicosis and environmental risks of pentobarbital-euthanized animals to clients. SAMPLE: A stratified random sample of AVMA members. METHODS: Over a 3-week period in early 2021, 16,831 of the AVMA's 99,500 members were surveyed, with 2,093 responses (a 12% response rate). Respondents were assigned to 1 of 3 categories on the basis of their answers: veterinarians euthanizing only food-producing species, veterinarians euthanizing only non-food-producing species, and veterinarians euthanizing both food-producing and non-food-producing species (ie, veterinarians euthanizing mixed species). RESULTS: Veterinarians responding to this survey appeared to be aware of the major methods of animal disposal, and about 89% reported communicating the method of euthanasia with clients to help ensure appropriate animal disposal. However, the need for additional education on local, state, and federal laws and rendering, as well as on risks of relay toxicosis including wildlife predation and environmental impacts, was reported. CLINICAL RELEVANCE: Survey results identified gaps in veterinarians' knowledge regarding animal disposal following pentobarbital euthanasia. Further education on this topic may be beneficial, particularly for early- and midcareer veterinarians who euthanize non-food-producing species and for veterinarians who euthanize mixed species in urban and suburban communities.

A literature review on current practices, knowledge, and viewpoints on pentobarbital euthanasia performed by veterinarians and animal remains disposal in the United States.

Sodium pentobarbital and pentobarbital combination products are commonly used by veterinarians throughout the US for euthanasia of their animal patients. The AVMA Guidelines for the Euthanasia of Animals: 2020 Edition lists barbiturate acid derivatives (pentobarbital) and pentobarbital combination products as an acceptable method of euthanasia for all species when circumstances permit their use. When using pentobarbital products, a veterinarian must consider appropriate handling and disposal of animal remains to avoid the potential for environmental contamination, relay toxicosis in wildlife or domestic animals, and contamination of the animal food supply. Failure to appropriately consider these facets of pentobarbital euthanasia can result in legal and ethical consequences. Despite these concerns, to the authors' knowledge no comprehensive literature review has been published concerning pentobarbital euthanasia or handling and disposal of animal remains following pentobarbital euthanasia. The literature review that follows aims to give a descriptive narrative of the most recent information available on the knowledge, use, challenges, and issues surrounding pentobarbital euthanasia and disposal of animal remains within the US.

Effects of participating in the annual Animal Welfare Assessment Contest on veterinary students' self-perceived knowledge of and attitudes toward animal welfare science and their career choices.

OBJECTIVE: To evaluate the impact of participating in the annual Animal Welfare Assessment Contest (AWJAC) on veterinary students' self-perceived knowledge of and attitudes toward animal welfare science and on participants' career choices. SAMPLE: 46 veterinary students who participated in the AWJAC from 2014 through 2017. PROCEDURES: The study consisted of 2 parts. In part 1, a survey regarding participation in the AWJAC was emailed to all 138 veterinary students who participated in the contest from 2014 through 2017. In part 2, a self-selected subset of 4 survey respondents were interviewed by telephone regarding their AWJAC experience. RESULTS: Forty-six of 138 (33%) AWJAC participants responded to the online survey. When respondents were asked to rate the attitudes they held before and after participating in the AWJAC, significant increases were identified for engaging with animal welfare topics in their professional decision-making, making career choices based on their interest in animal welfare, and having their interest in animal welfare shape their professional career choices. Analysis of telephone interview transcripts revealed 3 major themes regarding AWJAC participation: defining animal welfare, the value of networking, and professional preparedness. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that participation in the AWJAC heightened veterinary students' self-perceived awareness of animal welfare science, provided participants an opportunity to expand their professional networks, and prepared participants for entrance into the veterinary profession by enhancing communication and critical thinking skills.
