Who provides the risk identification in an outbreak?

• A. FDA
• B. CDC (non-regulatory)
• C. EPA
• D. USDA

Answer: (B)

When an outbreak happens, identifying the risk and its source is driven by public health investigation led by the CDC. They gather and analyze case data, use descriptive epidemiology to see patterns by person, place, and time, and conduct analytic studies to link illnesses to a common exposure, such as a specific food or setting. They coordinate with state and local health departments, laboratories, and other partners, then translate those findings into risk communication to protect the public. The CDC operates in a non-regulatory role, focusing on surveillance, outbreak investigation, and risk messaging, while regulatory agencies like the FDA, USDA, and EPA carry out safety enforcement and actions such as recalls based on outbreak findings. This combination means the critical step of pinpointing the risk during an outbreak is primarily the CDC’s epidemiologic work.
