Which agency is responsible for investigating food-borne illnesses?

The agency responsible for investigating food-borne illnesses is Public Health (PH). This agency focuses on the health of the community at large and has a critical role in monitoring and protecting public health, which includes managing outbreaks associated with food safety. Public health officials conduct investigations to track the sources of foodborne illnesses, analyze patterns, and implement preventive measures to reduce future incidences.

Other options like Bioenvironmental Engineering may deal with broader environmental health issues, and while Environmental Health could relate to food safety, it is often more concerned with the interactions between the environment and human health rather than direct investigations of illnesses. Installation ground safety focuses more on the safety of personnel within a specific installation, rather than the public health implications of foodborne diseases.
