Prenatal Exposure to Certain Pesticides Linked to Infant Neuroblastoma

A new study published in Environmental Research finds that prenatal exposure to specific pesticides increases the risk of neuroblastoma, a rare but deadly cancer in infants. Researchers at the University of North Texas analyzed data from over 200,000 children born in California between 1998 and 2016, including 199 cases of neuroblastoma.

The study identified four pesticides—flonicamid, cypermethrin, permethrin, and benomyl—associated with higher cancer risk, increasing the likelihood of neuroblastoma by 33%, 53%, 24%, and 20%, respectively. Flonicamid and cypermethrin are commonly used on cotton and other crops, while permethrin is also used in mosquito control. Benomyl was banned in 2001 due to toxicity concerns.

The research underscores the challenges of tracking pesticide-related health risks, as compounds evolve and usage patterns change. Authors hope the findings inform regulatory agencies, including the EPA and the World Health Organization, to better protect public health and reduce exposure for pregnant women.
