In February 2017, the Nutrition Policy Institute and the Public Health Alliance of Southern California initiated a multisector collaboration among California state agencies to raise awareness about food waste. After development and distribution of a Communications Guide, Food Waste Prevention Week was launched successfully in March 2018, with official support from California's Governor, Secretary of Agriculture, Superintendent of Public Instruction, and other leaders. The multiagency shared messaging campaign was estimated to reach millions, based on unique page views via social and traditional media. In a follow-up survey, partners expressed satisfaction with Food Waste Prevention Week and interest in participating in future efforts. Organizing leaders across multiple sectors to raise awareness about food waste is possible; such efforts can contribute to driving behavioral and structural changes to reduce food waste. © 2019 Wolters Kluwer Health, Inc.
