On a July afternoon in 2006, Patrick Hale microwaved a bag of popcorn for his two young children and sat down with them to watch television. When he got up to change the channel, he heard a strange noise behind him, and turned to see his 23-month-old daughter, Allison, turning purple and unable to breathe.

As a Marine, he was certified in CPR, but he could not dislodge the popcorn with blows to her back and finger swipes down her throat. He called 911, but it was too late: by the time Allison arrived at the hospital, her heart had stopped beating. An autopsy found that she had inhaled pieces of popcorn into her vocal cords, her bronchial tubes and a lung.

“Neither one of us knew that popcorn was unsafe,” said her mother, Christie Hale of Keller, Tex.

Now, the American Academy of Pediatrics, the nation’s leading pediatricians’ group, wants that to change. Saying that food should be subject to as much scrutiny as toys, it is calling on the Food and Drug Administration to require warning labels on foods that are known choking hazards, and to evaluate and monitor food for safety.

“You have a SuperBall that by government regulation has to carry warnings telling people it’s a risk to young children and you can’t market it to them, yet you can have the same identical shape and size gumball and there are no restrictions or requirements,” said Dr. Gary Smith, director of the Center for Injury Research and Policy at Nationwide Children’s Hospital in Columbus, Ohio, the lead author of the pediatricians’ policy statement on food hazards.
