Enrique M. Ostrea, Wayne State University professor of pediatrics, commented about the possibility that researchers have discovered certain fatty acid ethyl esters (FAEEs) in meconium that may provide a biomarker for fetal alcohol exposure. "There are only a few biomarkers that indicate if an infant has been exposed to alcohol during pregnancy, and most of them are not strictly associated with alcohol use," Ostrea said. "In this study, we have found a direct association between the presence of certain FAEEs and alcohol use."
