The Mission of the California Department of Food and Agriculture (CDFA) is to safeguard a resilient food system and promote an equitable marketplace, cultivating a California grown food supply that is globally recognized for innovation, quality, and sustainability.
The Center for Analytical Chemistry (CAC) provides analytical expertise in environmental, food, and fertilizer safety, and in issues concerning crop protection, farm worker safety, data gathering activities, and emergency response. The Center is comprised of two main programs: Environmental Safety and Food Safety. The Environmental Safety laboratories (ESL) provide vital analytical support to the California Department of Pesticide Regulation (DPR) and California Environmental Protection Agency (CalEPA) by performing soil, water, and air analyses mandated by various environmental laws; monitoring pesticide exposure of field workers; and by performing regulatory testing of pesticides for label compliance. ESL also assists the Feed, Fertilizer, and Livestock Drugs Regulatory Services branch (FFLDRS) through the provision of label compliance testing of commercial fertilizers. The Food Safety laboratories (FSL) support DPR, US Department of Agriculture (USDA), and US Environmental Protection Agency (US-EPA) in their legislative tasks as well as the California County Agricultural Commissioners in their enforcement activities by conducting chemical analyses on environmental and food samples to monitor for and collect data on hazardous agrochemicals such as pesticides and their metabolites. The independent Quality Assurance (QA) section provides support to the CAC in the implementation and management of International Standards Organization (ISO) 17025 accreditation program, quality assurance of its testing activities, method reviews and validation and compliance audits.
