Medically reviewed by Andrea Chisholm, MD FACOG
If you're currently expecting, you are likely thinking about certain ingredients and substances you might come into contact with, like cat litter or certain kinds of foods. One substance that raises questions is black mold, and whether or not it might harm you or your fetus.
The good news is that black mold is not likely to hurt you or your pregnancy, but that doesn't mean it is safe in your home. Read on to learn more about what black mold is, how it impacts pregnancy, and what you should do if you happen to discover it in your home.
What Is Black Mold?
Black mold, or Stachybotrys chartarum, is a slow-growing mold that appears black or greenish and grows on cellulose materials where there is a moisture or water problem. If you have black mold in your home, you'll likely encounter it in your kitchen, bathroom, or basement, where there is the highest risk of water damage. Black mold is covered in slime, which prevents it from drying out and becoming airborne, so the risk of breathing it in is low.
If you have black mold in your home, you'll likely find it on these types of surfaces several months after water damage has occurred:
Carpets
Sheetrock
Wallpaper
Insulation
Wood
Cotton or paper

Will Exposure to Black Mold During Pregnancy Harm a Fetus?
No scientific studies show a direct link between exposure to black mold and negative health impacts on a growing fetus or the pregnant parent. However, that does not mean that exposure to black mold is free of health risks. Many people think that black mold causes health problems, but according to research data, mold or fungi are unlikely to make people sick. Instead, some molds can create toxins that may trigger specific allergies in people, particularly those with asthma issues.
One reason there is a lack of research on how black mold can affect pregnancy is that it is unethical to expose a pregnant person to anything that poses a danger to their pregnancy. Instead, researchers can—and have—conducted rigorous studies on how mold affects people who are not pregnant. What they found is that black molds, like other forms of mold and fungi, can create toxins, and those toxins can potentially make people sick.
How sick a person gets largely depends on how they react to allergens. The worst reactions to molds tend to be hayfever-like symptoms. These symptoms can include:
Runny nose
Watery eyes
Asthma-like symptoms
Skin rash such as hives
Coughing
Post-nasal drip
Itching in the eyes, nose, and throat
Dry, itchy, scaly skin
Animal studies have shown that when pregnant mice are exposed to black mold, there is an increased rate of miscarriage. However, it is not known that a human response would be the same. For that reason, it is advised that pregnant people avoid exposure to any mold, including black mold.

What To Do if You Find Black Mold in Your Home

Black mold can be frustrating to get rid of. And because of the risk of getting sick, it is important to get rid of all of it to prevent it from growing back. Therefore, it is wise to throw away as much as possible, especially if the mold is on carpets, clothing, toys, books, furniture, and other things you are likely to touch.

Call a professional cleaner
Cleaning black mold may not be something you can do easily or safely, especially if you are pregnant. In that case, it might be best to call a professional cleaner who can remove the mold problem once and for all. Since molds can be toxic and cause illness, it is best to choose a professional cleaning company that has been certified by the Institute of Inspection Cleaning and Restoration Certification (IICRC). Companies that are certified by IICRC have the proper training and equipment to clean your home thoroughly.

Make a DIY mold cleaner
For some patches, like on bathroom tiles or other isolated areas, you can clean the mold by making your own spray or using household cleaners. Although it's best to avoid using harsh chemical cleaners while pregnant, here are a few to consider:
Chemical mold and mildew removers
All-purpose cleaners
Vinegar (not bleach)
Dish detergent
If you're concerned about using harsh chemicals to clean mold in your home, you can effectively kill black mold by mixing a solution of water and baking soda. For more information on how to handle mold in your home, you can read up on safety and clean-up efforts at the Environmental Protection Agency.
The Bottom Line
Black mold is not likely to adversely affect your pregnancy; however, it can make you and your family sick. Mold is not considered safe and should be removed from your home. That said, if you have been exposed to mold, you can put your mind at ease by calling your doctor and bringing up any concerns.
To prevent black mold from forming in your home, do an inspection to check for high moisture areas, leaky pipes and faucets, or any other water damage and don't be afraid to call a professional cleaner for help. If you find yourself with further questions about mold exposure and pregnancy, be sure to reach out to an OB-GYN or health care provider.
