Is BPA From Plastic Food Containers a Miscarriage Concern?
BPA can migrate from some plastic containers. Human case-control research links higher urinary BPA with recurrent miscarriage, but it does not prove one container causes miscarriage.
What is the concern?
BPA is an endocrine-disrupting compound used in some plastic and food-contact materials. It can move from plastic into food, especially when plastic is heated, scratched, old, or used with oily foods.
Pregnancy loss is serious and never something to blame on one household item. The honest question is smaller: does BPA exposure belong on the list of exposures worth reducing while trying to conceive or during pregnancy?
What the research says
A 2025 Journal of Xenobiotics review found that compounds can migrate from plastic containers used for food and medicine. The review named phthalates and endocrine-disrupting compounds such as BPA among the most studied substances.
A 2015 PLoS One case-control study in eastern China measured urinary BPA in women with unexplained recurrent miscarriage and controls. Women with higher urinary BPA had higher odds of recurrent miscarriage, including adjusted odds ratios of 3.91 and 9.34 in higher exposure groups compared with the lowest group.
What this means at home
This does not prove that BPA from one food container causes miscarriage. It does support reducing avoidable BPA exposure from food contact, especially for people trying to conceive or already pregnant.
Use glass containers for leftovers, baby snacks, and warm meals. Avoid microwaving food in plastic. Replace scratched plastic food containers first.

What to use instead
Glass storage helps lower the amount of plastic touching food, especially for leftovers, snacks, and foods that may be warmed later.
