Wasted Food Pilots Raise Consumer Awareness
King County, Washington’s display at a farmers market, which included information on how to keep the produce being purchased fresh, was popular and effective to recruit participants for its Food: Too Good To Waste (FTGTW) Challenge.

Pilot testing of the Food: Too Good To Waste toolkit in 15 communities illustrated that measuring household food waste activated participants’ natural tendency to avoid wasting.
