Cal. Food and Agricultural Code § 58749

The director may issue and make effective a marketing order or marketing agreement which applies to two or more commodities. The producers or handlers of each commodity encompassed by such marketing order or agreement shall have all rights and privileges contained in this chapter as though such producers or handlers were directly affected by a marketing order or agreement regulating only a single commodity. If the producers or handlers of one commodity who are directly affected by a marketing order or agreement which applies to two or more commodities act to enjoin, amend, suspend or terminate the provisions thereof to such commodity, the order or agreement shall not be enjoined, amended, suspended or terminated with respect to any other commodity regulated by such order or agreement unless the director finds such injunction, amendment, suspension, or termination respecting one commodity makes continuance of the order or agreement no longer feasible or it fails to attain the objectives of this chapter. Unless the director makes findings to the contrary, a marketing order or agreement applicable to more than one commodity is deemed to be severable with respect to each commodity encompassed by it and also severable as to each sentence, clause, or part as it applies to each commodity. There shall be a clear and concise definition or identification of each commodity regulated by such multiple commodity marketing order or agreement.
