Mr. Yuk

Mr. Yuk is a trademarked graphic image, created by the Children's Hospital of Pittsburgh, and widely employed in the United States in labeling of substances that are poisonous if ingested.

History

To help children learn to avoid ingesting poisons, Mr. Yuk was conceived by Richard Moriarty, a pediatrician and clinical professor of pediatrics at the University of Pittsburgh School of Medicine who founded the Pittsburgh Poison Center and the National Poison Center Network. Moriarty felt that the traditional skull and crossbones representing poison was no longer appropriate for children.

Design

Mr. Yuk and his graphic rendering are registered trademarks and service marks of the Children's Hospital of Pittsburgh of UPMC, and the rendering itself is additionally protected by copyright. The design of Mr. Yuk was made to be a distinctive symbol that children would recognize and associate with a verbal "No."

Usage

Mr. Yuk stickers featuring the symbol are attached to poisonous substances, and Mr. Yuk's distinctive, grimacing face warns children about the potential dangers of ingesting chemicals or medicines.
