Newborns May Feel the Effects of Pesticides Even Before Conception

Pesticide Exposure Near Farms Linked to Lower Newborn Health Scores

Researchers have found that women who live near farms where pesticides are used can give birth to babies with poorer health scores, even if the exposure happened before they become pregnant.

The study examined more than 1.1 million births in Arizona from 2006 to 2020, using the Apgar score—a quick check of a baby’s heart rate, breathing, muscle tone, reflexes and skin color—to gauge early health.

A higher chance of low scores was linked to several common chemicals, such as carbaryl and formetanate hydrochloride.

Because pesticides are meant to be harmful, their chemicals can also affect humans, the scientists warned. The research only shows a link, not proof that pesticides directly cause these health issues.

Future work will look at long‑term outcomes using Medicaid data to see if early exposure leads to developmental problems later.

Farmers are urged to consider less toxic options, but a complete ban on all pesticides is not suggested.

Women who suspect they’ve been exposed should discuss this with their doctor, the study team said. Those living near agricultural areas can reduce exposure by:

• cleaning regularly,
• using doormats and removing shoes indoors,
• installing water filters if they use well water, and
• changing air filters often during spraying seasons.

It’s also wise to avoid household insecticides containing ingredients like beta‑cyfluthrin or cypermethrin, especially during pregnancy.

The main takeaway: lower pesticide use and better indoor practices may help protect the newest members of a family.
