Can PFAS exposure from food packaging and nonstick pans affect your child's birth outcomes in Japan?

What's actually in it

PFAS from nonstick cookware, food packaging, and waterproof fabrics build up in every pregnant woman's blood. In Japan, where fish consumption is high, additional PFAS exposure comes from seafood. The Japan Environment and Children's Study (JECS) is one of the world's largest birth cohorts tracking these effects.

What the research says

A 2026 study in Environ Pollut from the JECS cohort examined PFAS exposure and birth outcomes. The researchers found associations between PFAS levels and adverse obstetric and birth outcomes. Interestingly, maternal endometriosis history modified the effects, suggesting some women are more vulnerable.

The findings add to the global evidence that PFAS affect pregnancy health across diverse populations and dietary patterns.

Reduce PFAS by filtering water, choosing PFAS-free cookware, and varying your fish sources. Pregnant women with endometriosis may want to be especially careful about PFAS exposure.
