"It's really important after attending one of these petting zoos to wash your hands thoroughly with soap and water. Sanitizer is as good as soap and water if there's no visible dirt or debris but if you see dirt, you must use soap. Ideally you should try to use both if you can," said Dr. Johanna Goldfarb, director of the Cleveland Clinic's Center for Pediatric Infectious Disease.
Goldfarb also said that careful handwashing rules should apply whether children are visiting the petting zoo or the mall, especially before eating.
"You don't know where their hands have been and you don't know what's on everything they've touched," she said.
The LeFevers initially are seeking a minimum of $10,000 in damages for negligence, and medical and funeral expenses. Pritzker said he expected to ask the court for a substantially greater sum.
