Final answer:
The manufacturing of chicken noodle soup is regulated by the FDA, with the FSIS also playing a role if the soup contains chicken.
Step-by-step explanation:
The agency responsible for regulating the manufacturing of chicken noodle soup is the Food and Drug Administration (FDA). This federal agency is tasked with ensuring public health by regulating and supervising food safety, which includes the oversight of the quality of substances sold as food in the United States. The FDA also monitors claims made in the labeling of foods regarding their composition and health benefits.
The Food Safety and Inspection Service (FSIS), part of the U.S. Department of Agriculture, is responsible for regulating meat, poultry, and egg products, so if the soup contains chicken, the FSIS would also have a regulatory role.
