What must an animal crematory's storage facility do with animal remains?

The correct practice for an animal crematory's storage facility is to chill animal remains to at least 40°F. This temperature helps to reduce the growth of bacteria and slows down the decomposition process of the remains, ensuring that they remain in a condition suitable for later cremation. Maintaining a temperature below 40°F is crucial for public health and safety, as it prevents the spread of odors and potential pathogens that could arise from decomposing animal matter.

In contrast, the other options do not effectively safeguard the remains. Storing remains at room temperature or leaving them open to the environment would lead to rapid deterioration and could pose health risks. Furthermore, chilling to at least 50°F is insufficient regarding industry standards and best practices for storage of animal remains. Thus, the requirement to keep remains at or below 40°F is pivotal for the proper handling within a crematory setting.
