The Science Behind Orange Mold

There are over 100,000+ species of mold fungi worldwide, and over 1,000+ living in the U.S; Some are harmless, some beneficial, and others can be dangerous. In this article, we’re talking about Orange Mold. Unlike most molds, which are usually fuzzy, orange mold often appears slimy and spongy.

Like any mold, orange mold or orange-colored mold needs a food source, as a result, it grows on foods, wood, and other materials, starting as small dark spots before turning its characteristic orange color.

Oftentimes, orange mold is a combination of multiple species of mold co-existing with each other; making individuals who are more susceptible to mold constantly sick and aggravating old symptoms and illnesses.

So, Why Are Orange Mold…Orange?

The orange color of orange mold is due to the pigments produced by certain mold species, influenced by their environment and nutrient sources. Different mold strains, such as Aspergillus, Acremonium, and Fuligo septica, can produce orange spores. 

The substrate the mold grows on can also impact its color, as specific nutrients and organic materials can cause molds to generate particular pigments. Environmental conditions like humidity, temperature, and light play a role as well, with some molds developing more intense colors under certain circumstances. 

These pigments serve various functions, including protection from UV light and oxidative stress, and inhibiting the growth of competing microorganisms. Thus, the vibrant orange hue results from a complex interplay of species, environment, and nutrition.

Is Orange Mold Dangerous?

The danger of mold is really about who is vulnerable to that specific species of mold by inhaling their toxins, which means all mold in a way is dangerous, but some mold produce more mycotoxins than others. Inhaling the mycotoxin spores from toxic molds is especially dangerous for individuals with weakened immune systems, leading to symptoms such as constant respiratory irritations, runny eyes, and coughing.

Contacting a mold expert is one of the best ways to know, the severity of the infestation, the length of exposure, spores counts, and how dangerous it actually is for the health of the occupants. 

Common Types of Orange Mold:

Orange mold can be categorized into four subtypes, each with distinct appearances and varying levels of toxicity.

Acremonium:

This mold generally has minimal impact on healthy individuals but can pose a risk to those with weakened immune systems. It grows slowly, taking approximately five days to develop. As it matures, it takes on a leathery appearance and can be orange, gray, or pinkish in color.

Fuligo Septica:

This mold is often revolting in appearance, earning it the nickname “dog vomit slime” due to its resemblance. Primarily found outdoors, it typically displays hues of orange or yellow. As its nutrients diminish, it adapts its appearance to mimic other molds. While generally harmless to humans, its dusty spores can cause irritation when inhaled by those with sensitivities.

Orange Slime:

Take a guess at the appearance of this mold based on its name – “sludge mold.” It’s also known for its presence on trees. Generally regarded as more of a nuisance, it’s essentially harmless to humans.

Aleuria Aurantia:

This fungus stands out with its resemblance to orange peel, often dubbed “orange peel fungus” for this reason. It’s widespread and boasts a vibrant orange hue, typically taking on a cup or saucer shape akin to a discarded orange peel. In terms of toxicity, Aleuria mold is entirely safe to consume without any adverse effects.

Common Areas for Orange Mold to Grow

Like all molds, orange mold thrives in moist environments. However, unlike other molds, it particularly favors wood surfaces. You’ll typically find it in:

Attics: Poor ventilation and potential roof leaks create a damp environment ideal for mold growth, especially on wooden beams and rafters.

On The Wall: Orange mold on walls often happens after long exposure of water damage of the wall, where you might see light orange moldy stains starts to grow.

Bathrooms: orange mold in bathroom are common, especially at the corner of ceiling near the showers, at the base of the toilet or around baseboards.

Kitchens: Frequent water use, steam from cooking, and occasional spills provide the moisture needed for the mold to develop on wooden cabinets, countertops, and behind appliances.

Wooden Window Sills: Condensation from temperature differences between indoors and outdoors can create a moist surface, making these areas susceptible to mold growth.

Mulch: Organic material like mulch retains moisture, creating a perfect breeding ground for mold, including orange mold.

Gardens: Outdoor wooden structures, such as fences, garden beds, and decks, can develop orange mold due to exposure to rain and humidity.

How Can Mold Impact Your health?

Discovering mold in your home or workplace might not automatically lead to illness for you or others present. However, contact or inhalation of mold can trigger various allergy-like symptoms, including:

  • Irritation of the eyes
  • Sneezing
  • Sore throat
  • Headaches
  • Skin rashes
  • Irritation of the lungs
  • Runny nose
  • Congestion
  • Wheezing

Individuals with conditions like asthma, cystic fibrosis, or weakened immune systems are at a higher risk of experiencing complications such as infections or severe allergic reactions like Hypersensitivity Pneumonitis. The severity of the reaction often correlates with the amount of mold present.

Mold is dangerous as it can cause allergic reaction to those who are susceptible to it.
