What is the California Department of Public Health (CDPH) doing about foodborne illnesses and outbreaks?
Healthcare providers tell their local (county) health department about cases of foodborne illness, and in turn, local health departments tell CDPH so that public health officials can find and control outbreaks to prevent more people from getting sick. Health departments also gather lab test results from people who are sick. These tests are important because they help determine which people are getting sick by the same type of germ.
When CDPH learns of people who are getting sick by the same type of germ, they work with local, state, and federal health agencies to find out if the illnesses were caused by a common source, such as a contaminated food. CDPH and local health department officials may interview you over the phone to find out what you ate and did before you got sick. To help prevent more people from getting sick, public health officials may sometimes temporarily close a restaurant involved in an outbreak or remove contaminated food products from stores.
