In California, Agricultural Commissioners and Sealers of Weights and Measures are appointed in each of California's 58 counties by respective County Board of Supervisors. County Agricultural Commissioners and Sealers work cooperatively with the California Department of Food and Agriculture, California Environmental Protection Agency (CalEPA) and the Department of Pesticide Regulation (DPR) to provide protections to consumers, the environment, the agricultural industry, and to the marketplace.

Our role as County Sealers is to enforce the California Business and Professions Code and the California Code of Regulations pertaining to issues of equity in the marketplace and involving weights and measures matters, including the testing of packaged commodities for content and labeling accuracy.

Our mission as Sealers is to ensure that consumers have adequate and accurate information from package labels to facilitate meaningful and reliable value comparison.
