Final answer:
The Food and Drug Administration (FDA) is the agency that creates the voluntary "Food Code" to provide guidance on food safety practices.
Step-by-step explanation:
The federal agency that creates a voluntary, science-based "Food Code" with recommendations about food safety is the Food and Drug Administration (FDA). The FDA, part of the United States Department of Health and Human Services, is responsible for ensuring public health by regulating food safety, among other duties. They work in collaboration with other government agencies, including local health departments and the United States Department of Agriculture (USDA), to set and enforce strict hygiene standards in food handling. These regulations ensure that food can be traced back to its point of origin, which is crucial for tracking and managing foodborne disease outbreaks.
