Allergenic mold is not normally dangerous in small quantities, but can be a problem for people who are particularly allergic to mold or who have asthma. In large quantities it is more likely to be a problem for these individuals.
People who are particularly mold sensitive should avoid working with or disturbing moldy materials which might cause a reaction or increase their sensitivity.
The symptoms are like those of other allergies. Mold allergy symptoms include sneezing; runny or stuffy nose; itchy throat or inside of ears; hives; swollen eyelids and itchy eyes; and coughing, wheezing (a whistling sound when a person breathes), and trouble breathing.
More severe allergic reactions include:
Steps to help treat mold allergy
Several molds commonly found indoors may be a factor in triggering an asthma attack, including the most common genera, Cladosporium, Alternaria, Penicillium and Aspergillus.
It is a well known trigger for asthmatic attacks, and one of the most widespread molds.
Cladosporium growths appear green, brown or black. Outdoors, they grow on plant matter and release reproductive spores into the wind. Indoors, moist surfaces feed colonies, which infest indoor air currents with spores. Inhaling these particles causes allergic reactions in people with mold allergies. When colonies grow large enough, they will be visible as dark dots in wet areas, such as windows with condensation or bathroom shower stalls.
Alternaria sensitivity can lead to hay fever, and even severe and potentially fatal asthma. Studies have shown that up to 70 % of mold-allergic patients have skin test reactivity to Alternaria. Although most exposure is likely to occur outside, it can also be found in indoor environments. It can be commonly found from plants, soil, food and indoor air. It can also be noticed in damp situations, including textiles, electric cables, stored food, and cardboard and paper. The club-shaped spores are single or form long chains. They can grow thick colonies which are usually green, black, or gray.
Allergic symptoms can be as mild as dark circles or red rims under the eyes, sneezing, runny nose, watery eyes, and nose rubbing, to more moderate symptoms such as skin rash, blocked nose, itchy throat, conjunctivitis, swollen and crusted eyelids, chronic sinusitis, and post nasal drip. It can be found in soil, decaying vegetation, air and various substances. It can spoil food, colonize leather objects, and is an indicator organism for dampness indoors. The spores can trigger allergic reactions in individuals sensitive to mold. They are commonly called the blue or green molds because they produce enormous quantities of greenish, bluish or yellowish spores which give them their characteristic colors.
Frequently found in air and soil, it flourishes in decaying vegetation, foods, dusts, and water. In humid conditions, Aspergillus grow on leather and cloth fabrics. Some people with asthma or cystic fibrosis have an allergic reaction to aspergillus mold. Signs and symptoms of this condition, known as allergic bronchopulmonary aspergillosis include:
