Dangerous Fungi Found In Common Garden Soil
Recent research from the University of Georgia has identified a concerning presence of drug-resistant fungal infections in commonly used gardening products available at retail stores. Led by Professor Marin Brewer from UGA’s College of Agricultural and Environmental Sciences, the study focused on detecting Aspergillus fumigatus, a fungus found in soil, compost, and flower bulbs sold commercially.
Brewer emphasized the potential health risks associated with gardening activities involving these products, cautioning that while gardening is a popular hobby for stress relief, many individuals may be unaware of the fungal hazards present in their supplies. Aspergillus fumigatus, naturally occurring in soil, poses significant health risks when inhaled, particularly for those with compromised immune systems due to conditions like COPD, cystic fibrosis, diabetes, HIV/AIDS, or undergoing immunosuppressive therapies.
Between 2019 and 2021, the study sampled various gardening items and food products from major retailers, revealing more than 500 strains of A. fumigatus. Alarmingly, a substantial portion of these strains exhibited resistance to multiple antifungal medications. The resistant strains were notably prevalent in compost derived from manure, soil, and on flower bulbs such as daffodils, dahlias, gladioli, and tulips.
The study underscores global health concerns as Aspergillus fumigatus has been identified by the World Health Organization as a significant threat, affecting millions worldwide. Even healthy individuals can develop respiratory issues if exposed to this fungus, including the formation of lung clumps called aspergillomas, which may require antifungal treatment.
To mitigate the inhalation risk posed by fungal spores, Brewer recommends that individuals with compromised immune systems take precautions such as wearing N-95 masks while gardening. The study also highlights agricultural practices as contributing factors to fungal drug resistance, emphasizing the need for responsible use of antifungal agents in agriculture to reduce these risks.
Overall, the research calls for heightened awareness among gardeners, particularly those susceptible to fungal infections, and advocates for careful handling of gardening products to minimize health risks associated with drug-resistant fungi.
