Perfluorooctanoic Acid (PFOA)
What is it?
Perfluorooctanoic acid (PFOA) is a manufactured chemical that is part of a larger group of chemicals called perfluoroalkyls.
PFOA has been used in stain-resistant carpets and fabrics, nonstick cookware, and other products that resist heat, oil, stains, grease, and water.
Where is Perfluorooctanoic Acid (PFOA) found?
- Consumer products – production of nonstick cookware and products that resist heat, oil, stains, grease, and water
- Water – contaminated with PFOA
- Food – grown in soil or water contaminated with PFOA
How can I be exposed to Perfluorooctanoic Acid (PFOA)?
Perfluorooctanoic Acid (PFOA) commonly enter(s) the body through:
- Swallowing water or food that contains PFOA
- Touching products made with PFOA
What happens when I am exposed to Perfluorooctanoic Acid (PFOA)?
PFOA can remain in the body for long periods of time.
Exposure to PFOA can cause:
- Increased cholesterol
- Harmful effects to a developing fetus or breastfeeding infant
- Low infant birth weights
- Effects on the immune system, liver, and thyroid
Who is at risk for exposure to Perfluorooctanoic Acid (PFOA)?
- Some consumer products, foods, and water contain PFOA.
- Pregnant women and infants
- PFOA can harm a developing fetus or breastfeeding infant.
Reduce your risk
If you think your health has been affected by exposure to PFOA, contact your health care professional.
Always wash your hands thoroughly after handling chemicals. For poisoning emergencies or questions about possible poisons, please contact your local poison control center at 1-800-222-1222.
- Is your drinking water contaminated?
- Have your carpets or household fabrics been treated with PFOA?
- Do you use nonstick cookware?
- Use consumer products that do not contain PFOA.
- Routinely test your well water for PFOA.
- If your well water has high levels of PFOA, contact your local or state health agency or the Centers for Disease Control and Prevention (CDC) for information on how to reduce your exposure.
- If your well water contains PFOA above EPA’s drinking water advisory levels, choose bottled water for drinking and cooking or install an activated carbon water filters or reverse osmosis system.
- Use proper ventilation when buying or installing new carpets.
Keep children away from food, water, and products that may contain PFOA.
