× The federal government has shut down due to the failures of the President and Congress to continue government funding. Millions of Californians receiving benefits from state programs may be impacted. For now, California’s Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) will continue to provide services and enroll eligible families as long as funding is available. No new federal funding to California WIC will be provided until the President and Congress take action. Families should continue to use their WIC benefits and attend their WIC appointments. This information is subject to change, so please monitor the California WIC website for updates.

Please be wary of potential highly partisan political messaging while visiting federal government websites for information related to the federal government shutdown.

Public Health Laboratory Program

Public health laboratory services are essential to the core functions of public health. These services include disease surveillance, diagnosis of new and recurring infectious and zoonotic diseases, environmental and vector testing, toxicology, and monitoring the safety of drinking water, recreational water, and food supplies. Public health laboratories serve as reference laboratories for private, commercial laboratories in their respective service areas. The laboratory response to bioterrorism surveillance programs such as Biowatch and Biosense is the responsibility of the public health Laboratory Response Network (LRN). This Network also responds to any bioterrorism threats or public health emergencies.

LFS manages two programs: Public Health Laboratories and Certified Public Health Microbiologists.
