Final answer:
The statement that animals should not be disposed of until death is confirmed is true. This confirmation of death is essential due to legal and ethical responsibilities and to prevent the spread of zoonotic diseases.
Step-by-step explanation:
The statement "Animals may not be disposed of until death is confirmed" is true. It is a primary ethical and legal requirement to ensure that an animal has indeed died before it is disposed of. This is in line with guidelines provided by organizations such as the AVMA, which dictate that confirmation of death is necessary to prevent inhumane treatment and unnecessary suffering of animals. These guidelines are critical especially in contexts such as veterinary medicine where euthanasia is performed. It is also important from an environmental health standpoint, as the premature disposal of animals that are not dead can contribute to the spread of zoonotic diseases. Therefore, it is not only a matter of legal concern but also a question of ensuring the welfare of the animals and public health.
