It's important for parents to check Halloween candy before their children eat it, but the biggest risk Oct. 31 for little ghosts and goblins is being hit by a car. Physician Michael Palchak, director of the Pediatric Emergency Room at UC Davis Medical Center, says parents are usually more concerned about candy safety. "But by far the biggest concern for us is pediatric trauma from being hit by a car," he says. Dr. Palchak offers these suggestions for a safe Halloween: • Children should be escorted and supervised by an adult at all times. • Children should carry a flashlight so they're easily spotted as they cross the street. • Masks should have holes large enough so children can see out them. • Make sure Halloween costumes are bright or reflective and easily seen in the headlights. • Before children go out trick-or-treating, parents should talk to them about traffic safety and go over the rules again.
