Herbicide exposure may cause rare birth defect

The most common herbicide used in the U.S., atrazine, may be linked to the development of a rare birth defect called choanal atresia.

According to researchers at the Baylor College of Medicine, the herbicide, which is typically used on corn crops, may disrupt a woman’s endocrine system while she is pregnant, causing the defect.

This chemical is thought to be an ‘endocrine disruptor’ and may lead to the development of choanal atresia or stenosis, which is the less severe version of the defect. Choanal atresia is a congenital disorder that causes tissue to block the nasal passageway in one or both airways, resulting in difficulty breathing. Doctors may have to resuscitate a baby with choanal atresia upon delivery if the condition is severe. Additionally, surgery is usually required to remove the obstruction.

“One exposure that tipped in the direction [of atrazine] was maternal use of thyroid medications during pregnancy – there’s a hypothesis that hormones, and in particular, thyroid dysfunction, are related to choanal atresia risk,” Dr. Philip Lupo, an assistant professor in the department of pediatrics at Baylor College of Medicine, told
