Big, red #4 protects consumers from bad leftovers

4-day throw away

Food leftovers quickly can become unsafe and cause foodborne illnesses. That’s why a giant, red #4 has arrived with the message “after four days, throw it away!”

The “4-Day Throw Away” campaign, with #4 as its mascot, is informing consumers about the dangers of foodborne illnesses and the four-day guideline for eating, freezing or throwing away leftovers. Funded by a U.S. Department of Agriculture grant, it’s a partnership between ISU Extension and University of Nebraska-Lincoln Extension. Learn more on Facebook, Twitter and YouTube.
