THUNDER BAY – In the aftermath of any flood, there will be issues of mold and mildew that will come up. Drywall, wood, and furniture that was soaked is very vulnerable to mold and mildew. This is a serious problem, as it can impact the health of all persons in the affected homes.

This video from Health Canada is more geared toward prevention, but offers some information.


The Thunder Bay District Health Unit offers advise:

Observe these precautions when cleaning up

  • Keep children and pets out of the affected area until cleanup has been completed.
  • Wear rubber boots, rubber gloves, and goggles during cleanup of affected area.
  • Remove and discard items that cannot be washed and disinfected (such as, mattresses, carpeting, carpet padding, rugs, upholstered furniture, cosmetics, stuffed animals, baby toys, pillows, foam-rubber items, books, wall coverings, and most paper products).
  • Remove and discard drywall and insulation that has been contaminated with sewage or flood waters.
  • Thoroughly clean all hard surfaces (such as flooring, concrete, molding, wood and metal furniture, countertops, appliances, sinks, and other plumbing fixtures) with hot water and laundry or dish detergent, then disinfect with a solution of 1 cup of household bleach to 5 gallons of water. (Note: this solution should not be used for drinking, cooking, or personal hygiene.)
  • Help the drying process by using fans, air conditioning units, and dehumidifiers.
  • After completing the cleanup, wash your hands with soap and water. Use water that has been boiled for 1 minute (allow the water to cool before washing your hands).
  • Or you may use water that has been disinfected for personal hygiene use (solution of one eighth of a teaspoon of household bleach per 1 gallon of water). Let it stand for 30 minutes. If the water is cloudy, use a solution of ¼ teaspoon of household bleach per 1 gallon of water.
  • Wash all clothes worn during the cleanup in hot water and detergent. These clothes should be washed separately from uncontaminated clothes and linens.
  • Wash clothes contaminated with flood or sewage water in hot water and detergent. It is recommended that a laundromat be used for washing large quantities of clothes and linens until your onsite waste-water system has been professionally inspected and serviced.
  • Seek immediate medical attention if you become injured or ill.

The document attached at the bottom of this article covers recommendations from the Federal Emergency Management Agency in the United States.

FEMA states, “Exercise caution in cleaning and disinfecting molds because they release mold spores when disturbed.”
