Final answer:
Feed mills that are part of a farm are indeed exempt from registering as a food facility and are not subject to the FSMA animal foods rule, under specific compliance conditions.
Step-by-step explanation:
The statement that feed mills that are part of a farm are exempt from registering as a food facility and are not subject to the Food Safety Modernization Act (FSMA) animal foods rule is true. This exemption is specified under regulations pertaining to the FSMA, which focuses on preventing food contamination rather than responding to it. Farms that have their own feed mills to produce feed exclusively for animals on that farm typically meet the criteria for this exemption. However, it is essential for farms to be aware of and comply with all other applicable laws and regulations regarding the handling and production of animal feeds to ensure safety and quality.
