× 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.

Cal/OSHA Aerosol Transmissible Disease Standards

California passed the first two occupational standards in the nation to prevent worker illness from infectious diseases that can be transmitted by inhaling air that contains viruses, bacteria, or other disease organisms: 1) the Aerosol Transmissible Diseases (ATD) standard, which applies to workplaces at high risk for infectious diseases such as hospitals, clinics, emergency medical services, laboratories, prisons, and homeless shelters; and 2) the ATD Standard – Zoonotic, which protects workers from diseases spread to humans by animals.
