For which of the following animals must health records be maintained?

Health records are essential for animals covered under the USDA regulations, which primarily focus on animals used in research, exhibition, and commercial purposes. Maintaining health records for USDA-covered species ensures compliance with the Animal Welfare Act, which mandates that facilities adhere to specific animal care and use protocols. These records are crucial for monitoring the health and well-being of these animals, assessing their needs, and ensuring proper veterinary care is provided.

In addition, keeping accurate and up-to-date health records is vital for research integrity, allowing for informed decisions regarding animal welfare and the continuation of experiments. This practice not only supports ethical treatment but also aligns with regulatory requirements, which emphasize accountability in the care of animals used in various capacities within research and industry.

While health records for domestic pets, only research animals, or animals in experimental studies alone might be important in certain contexts, the USDA specifically encompasses a broader range of animals within its mandate, making it imperative to maintain health records for all animals covered under its framework.
