Mold is a type of fungus that can grow both indoors and outdoors and often thrive in damp or humid environments. While most mold is not harmful, some types can produce toxins (called mycotoxins) that can cause health problems in humans and animals.

So, what happens if you drink water that contains mold? In short, it depends on the type of mold and the amount of toxins present. Ingesting a few sips of moldy water is usually not harmful, but consuming large amounts can cause nausea, vomiting, and diarrhea. Sometimes, mold exposure can also lead to allergic reactions or respiratory problems.

While it’s unlikely that you’ll get sick from drinking moldy water, it’s still not advisable to do so. If you suspect that your water may be contaminated with mold, it’s best to contact your local water supplier or a qualified professional to have it tested.

For example, the fungus Aspergillus fumigatus can cause a serious respiratory infection known as aspergillosis. However, not all water molds are harmful to humans. In fact, some types of water mold are used to produce antibiotics and other medications.

Water mold is also an important food source for many aquatic animals, such as fish and crustaceans. Consequently, water mold plays a critical role in the food chain and the ecosystem’s overall health. So, it’s not always bad.

Likewise, the resulting moisture can also lead to mold spores to reproduce rapidly if you have a leaky roof or another source of water leakage.
