What organizations conduct research and investigate foodborne illness outbreaks?

The correct answer highlights the role of organizations that specialize in the investigation of foodborne illness outbreaks. The Centers for Disease Control and Prevention (CDC) plays a crucial role in monitoring health trends, including foodborne illnesses, across the United States. They collect and analyze data to identify outbreaks and provide guidance on prevention and control measures.

Alongside the CDC, the Public Health Service (PHS) collaborates on these matters, focusing on the overall health of the population and providing resources for public health initiatives. By working together, these agencies ensure a comprehensive approach to tracking, researching, and responding to foodborne illnesses, providing valuable insights that help to minimize risks to public health.

In contrast, while the FDA, USDA, state and local health departments, and international organizations such as the World Health Organization (WHO) and Environmental Protection Agency (EPA) contribute to food safety and health in various ways, their primary functions and focus differ from the specific investigative role of the CDC and PHS in the context of foodborne illness outbreaks.
