Water molds, also known as oomycetes, are primarily known for affecting plants and aquatic ecosystems. While they are not typically harmful to humans, some species can produce toxins that may pose health risks, particularly in cases of exposure to contaminated water or environments. Generally, the risk to human health is low, but individuals with compromised immune systems or allergies may experience adverse effects. Overall, maintaining good hygiene and avoiding contaminated water sources can minimize any potential risks.
