In Zambia, where hygiene and safety are critical issues in food processing, researchers are using a new tool to get their message across: a coloring book for kids. “Protect Yourself With Handwashing” features three smiling youngsters in a cartoon car of citrus, melons, and vegetables in vibrant hues. Though its target audience is children of employees at food processing and distribution centers in Lundazi and Mfuwe, the book also reminds parents that good hygiene begins at home.
