Bisphenol A (BPA) is used to make a hard plastic called polycarbonate. Until recently, BPA was also widely used to make the protective coatings inside food and drink cans, but US manufacturers have been phasing it out in response to consumer demand and scientific findings of serious health concerns. BPA may be in adhesives used to bond fabrics, such as for “no-stitch” clothing. It is also still used in some types of paper receipts.
Fact Sheet
BPA is found in
- Hard polycarbonate plastic in a variety of items, such as:
- Some kitchenware, like plates, mugs, and storage bottles.
- Eyeglass lenses, and screens for cell phones and laptop computers.
- Safety equipment, like helmets and protective visors.
- Parts for cars, light fixtures, and medical devices.
- Some protective coatings inside food cans; on household appliances; inside metal drinking water pipes; and on laminate flooring and concrete.
- Some clothing, including baby socks, blankets, and onesies.
- Some dental sealants.
- Some receipts printed on smooth shiny paper, such as from cash registers or gas pumps.
- Building materials, like sealants, adhesives, and grout.
Possible health concerns
- May harm the reproductive system in women.
- May interfere with the body’s natural hormones.
- May affect the fetus and infant, including possible changes in development and behavior.
- Might increase cancer risk.
Possible ways to reduce exposure
- Eat more fresh food and less canned food.
- Use glass or stainless steel containers for food and drinks.
- Request an electronic receipt, or no receipt, when possible. If you work as a cashier or otherwise frequently handle receipts, wear nitrile gloves.
- Because BPA can come out of products and collect in dust:
- Wash your and your child’s hands often, especially before preparing or eating food.
- Clean your floors regularly, using a wet mop or HEPA vacuum if possible, and use a damp cloth to dust.

Triclosan is used to kill bacteria. It was previously a common ingredient in liquid soaps labeled as “antibacterial” or “antimicrobial,” but this use was banned by the US Food and Drug Administration (FDA) as of September 2017. This is because there are no extra health benefits of using soap with triclosan compared to ordinary soap, and the wide use of antibacterials poses health concerns. Triclosan is still used in other personal care products, such as some toothpaste and cosmetics, although certain companies are phasing it out. It is also added to many household products and building materials.
Fact Sheet
Triclosan is found in
- Consumer products, including:
- Housewares, such as cutting boards, serving utensils, storage containers, humidifiers, and vacuum cleaners.
- Home furnishings, such as mattress and pillow covers, shower curtains, and rugs.
- Children’s toys and sporting goods, such as exercise, playground, camping, and boating equipment.
- Some personal care products, including some toothpaste and cosmetics like blush and eyeshadow; and combs, brushes, and razors.
- Building materials, such as some countertops, caulking, concrete, tiles, flooring, and bathroom fixtures.
Possible health concerns of triclosan
- May interfere with the body’s natural hormones.
- May make it harder for antibiotics to fight infections. This is because overuse of triclosan and other antibacterials may cause changes in bacteria that make them harder to kill.
Possible ways to reduce exposure to triclosan
- Avoid personal care products that list triclosan on the label, unless you have a medical reason for using them. For example, toothpaste with triclosan may help prevent gingivitis (inflammation of the gums).
- Avoid products labeled “antibacterial” or “antimicrobial.”
- For housewares and other consumer products, look for untreated materials, which could include wood, glass, stainless steel, and natural fabrics like wool. If you can’t tell whether a product has been treated with triclosan or other antibacterials, contact the manufacturer.

PCBs were once used in a wide variety of industrial applications, including as insulating fluid in electrical equipment and as plasticizers. PCBs were banned in the late 1970s but are still in some old equipment and products. They can also be unintentionally formed during the production of certain pigments and dyes. PCBs have spread through the environment and take a long time to break down.
Also see Hydroxy-PCBs.
Fact Sheet
PCBs are found in
- Some foods, including:
- Some fatty fish, like salmon and canned sardines. (Fatty fish are still good to eat. These fish are an excellent source of healthy fats [like "omega-3" fatty acids] and protein.)
- Some meat, such as high-fat ground beef.
- Some dairy products, such as milk.
- Some eggs.
- Some products and building materials made before 1980, such as:
- Caulk in older buildings, including schools.
- Some old fluorescent light fixtures.
- Some paint, wood floor finishes, plastics, and foam or fiberglass insulation.
- Certain pigments and dyes used in paints, paper products, plastics, and other items.
Possible health concerns of PCBs
PCBs:
- Can harm the developing fetus and infant, which can include effects on growth and learning.
- Can interfere with the body’s natural hormones and affect the immune system.
- May decrease fertility.
- Can increase cancer risk.
Possible ways to reduce exposure to PCBs
- Include plenty of variety in your diet.
- Trim off skin from fish and fat from meat, and cook these foods on a rack to let fat drain off.
- Because PCBs may be in dust:
- Wash your and your child’s hands often, especially before preparing or eating food.
- Clean your floors regularly, using a wet mop or HEPA vacuum if possible, and use a damp cloth to dust.
