CHICAGO – When 4-year-old Eric Stavros Adler choked to death on a piece of hot dog, his anguished mother never dreamed that the popular kids’ food could be so dangerous.

Some food makers including Oscar Mayer have warning labels about choking, but not nearly enough, says Joan Stavros Adler, Eric’s mom.

The American Academy of Pediatrics agrees. The nation’s largest pediatricians group is calling for sweeping changes in the way food is designed and labeled to minimize children’s chances for choking.

Choking kills more than 100 U.S. children 14 years old or younger each year and thousands more — 15,000 in 2001 — are treated in emergency rooms. Food is among the leading culprits, along with items such as coins and balloons. Of the 141 choking deaths in kids in 2006, 61 were food-related.

Surveillance systems lack detailed information about food choking incidents, which are thought to be underreported but remain a significant and under-appreciated problem, said Dr. Gary Smith, director of the Center for Injury Research and Policy at Nationwide Children’s Hospital in Columbus, Ohio.

Smith is lead author of a new policy report from the pediatrics academy that seeks to make choking prevention a priority for government and food makers. The report was released today in the journal Pediatrics.

Doctors say high-risk foods — including hot dogs, raw carrots, grapes and apples — should be cut into pea-sized pieces for small children to reduce chances of choking. Some say other risky foods, including hard candies, popcorn, peanuts and marshmallows, shouldn’t be given to young children at all.

Federal law requires choking warning labels on certain toys including small balls, balloons and games with small parts. Unless food makers voluntarily put more warning labels on high-risk foods, there should be a similar mandate for food, the pediatrics academy says.

The group also urges the Food and Drug Administration to work with other government agencies to establish a nationwide food-related choking reporting system, and to recall foods linked with choking.

Adler, a Warren, N.J., lawyer who pushed for more warning labels after her son died in 2001, considered herself educated about children’s safety. Her son had eaten hot dogs before without any problem.

Hot dogs are ”almost as American as apple pie,” she said. ”You really don’t know how horrible it can be.”
