As the academic year begins, college students face a potential health hazard in their dormitories: mold. Experts are warning that mold poisoning, often overlooked and difficult to detect, can lead to a range of health problems, from minor irritations to severe long-term damage.
Multiple lawsuits have been filed against universities in the past year, alleging that students were housed in dormitories contaminated with mold. These legal actions include a $35 million suit against Sewanee University of the South, with students claiming mold exposure caused asthma and nosebleeds, and a suit against Dallas Baptist University where 48 students alleged knowing exposure to mold-contaminated residences. Similar cases have also been reported at Lipscomb University and Spring Hill College.
Contributing Factors to Mold Growth
Dr. Alan W. Gruning, President and Medical Director of the International Center for Health and Wellness, described the issue as an epidemic on college campuses. He cited high humidity, inadequate maintenance, contaminated air conditioning systems, hygiene problems, and frequent leaks as ideal conditions for mold proliferation. Gruning noted that older campuses are particularly susceptible as buildings age and are affected by increased instances of hurricanes and flooding.
Symptoms and Health Impacts
Mold is ubiquitous, and for most people, exposure poses no significant health risk. However, for sensitive individuals, certain types of mold can trigger adverse reactions. Dr. Racheal Onah, a consulting physician at RealTime Labs, explained that initial symptoms can include irritated eyes, skin, or nasal passages, sinus pressure, and headaches. Over time, these can escalate to debilitating fatigue, brain fog, joint pain, heart palpitations, and gastrointestinal distress.
In severe cases, high levels of mold exposure can lead to neuroinflammation, cognitive dysfunction, neurodegenerative patterns, significant immune suppression, and even liver and kidney damage. The severity and onset of symptoms depend on the individual, the type of mold, and the extent of exposure. Some individuals may develop symptoms within days, while for others, it may take months.
Gruning highlighted that individuals with conditions like "Biotoxin Illness" or "Chronic Inflammatory Response Syndrome (CIRS)" are genetically predisposed to mold sensitivity, leading to chronic inflammation and a constellation of symptoms that can be misdiagnosed. The Centers for Disease Control and Prevention (CDC) refers to severe, life-threatening reactions as "invasive mold infections" (IMIs), noting they are rare but serious.
Detecting and Addressing Mold Issues
Experts advise a proactive approach to identifying potential mold problems. Gruning recommends an initial inspection upon arrival in a dorm room: smelling for musty or stale odors, which he states are almost always indicative of mold or bacteria, and looking for signs of water damage such as ceiling stains, peeling paint near windows, or warped flooring. He advises against occupying spaces with these indicators.
For students already moved in, Onah suggests documenting the onset and location of symptoms and inquiring with fellow residents about similar issues. Documenting any visible mold growth, water damage, or condensation with photographs is also recommended. Seeking medical evaluation, particularly for persistent or severe symptoms, is advised. Diagnostic tests, such as a urinary mycotoxin test, can indicate current exposure.
Gruning and Onah both recommend specialized environmental testing for mold, suggesting the ERMI test from EnviroBiomics or the EMMA (Environmental Mold and Mycotoxin Assessment) test. They acknowledge that mold can be hidden behind walls, under floors, or within air conditioning units, making visual inspection insufficient.
Remediation and Prevention
Experts caution against common DIY mold removal methods. Onah warns that using bleach can be counterproductive, as it removes surface stains without eradicating the mold's root system, which can then release more spores when moisture is present. Steam cleaning hardwood floors or shampooing carpets without proper ventilation and drying can also worsen the problem by driving moisture deeper into materials.
While HEPA air filtration can offer some relief, it does not address the source of the mold. Professional mold remediation is recommended for thorough cleaning of concealed areas such as within drywall, ceiling tiles, carpets, and upholstery. Gruning emphasizes the importance of acting proactively and vacating a space if any issues are detected.
