A MOULDY ISSUE

By  Dr.Yaron Atzmon*

Now that the rainy season has started and winter is fast approaching, homeowners will have to continually deal with the presence of mould and mildew in the house. These microscopic fungal organisms thrive specifically in areas with temperatures between 10-32 degrees Celsius and high humidity (>60%), like that of Hà Nội.

Certain species of mould, like Aspergillus or Penicillium, are greatly beneficial to mankind. They are industrially used for the production of cheese and antibiotics. But these moulds produce mycotoxins, or poisonous substances which causes health problems.

Stachybotrys, or ‘black mould’, is usually found in water-damaged houses due to flooding or roof leaks. They thrive in material with high cellulose content, like wood, paper, tiles, and carpets. Their toxins can cause fever, headaches, fatigue, allergic symptoms, and irritation of the respiratory tract.

Penicillium spp. are widespread and found in air, decaying vegetation, and soil. The production of which commonly occurs in cereal grains and cold climates. Infection is called penicillosis, affecting the respiratory and urinary tracts.

Aspergillus causes aspergillosis in individuals with weakened immune systems. It can also cause skin lesions and ulcers. This mould usually contaminates starchy foods such as bread and potatoes. It produces aflatoxin, which is found in nuts.

Here are some tips to minimise mould growth in the home:

  • Use dehumidifiers to keep humidity below 60%
  • Seal all air leaks on the exterior of the building/house
  • Use exhaust fans in the shower and in the kitchen
  • Thoroughly clean floors and furniture with a  HEPA (high efficiency particulate air) vacuum cleaner like Electrolux
  • Scrub mould on walls using a plastic scrubber dipped in a bleach solution (1/2 cup of chlorine bleach + 1/3 cup of  laundry detergent + 1 gallon of hot water)

In a Mayo Clinic study (1999), mould was implicated as a major cause behind chronic sinusitis.

At Family Medical Practice, we have seen a rise in  cases  of allergic reactions and asthma attacks during winter. It would be wise to consult your doctor if you notice symptoms which might be related to mould exposure.—Family Medical Practice Hanoi
