This page was reviewed or revised on Thursday, September 22, 2011 2:50 PM


If a Boil Water Advisory is issued follow these steps to safely clean and disinfect your dishes, tableware, cutting boards and countertops.


What is Disinfection?

You can wash dishes by hand in 1 of 3 ways:

  1. Wash dishes in soap and water that has been brought to a rolling boil for 1 minute and allowed to cool so it is not too hot to touch.
     
  2. Wash dishes in soap and hot tap water then rinse in water that has been brought to a rolling boil for 1 minute and allowed to cool so it is not too hot to touch
     
  3. Wash dishes in soap and hot tap water and then rinse in the following disinfection solution. Mix about 30 ml (6 teaspoons) of bleach in 13.5 litres (3.5 gallons) of water and let stand for at least 10 minutes. Soak dishes in the solution for at least 1minutes. Let the dishes air dry.


Washing Dishes Using a Dishwasher

Wash dishes using a dishwasher in 1 of 2 ways:

  1. Use your dishwasher’s “hot” setting. It safely disinfects dishes.
     
  2. For dishwashers without a “hot” setting, finish the cycle then rinse them in a “disinfection” solution.


Cleaning Chopping Boards, Countertops and Cooking Utensils

First, clean with warm, soapy water. Then wipe with the following solution:

  • Mix about 30 ml of bleach in 4.5 litres (1 gallon) of water and let stand for at least 10 minutes. Keep in a tightly sealed container.

This solution is stronger than the one used for rinsing dishes. Do not reuse or store this solution. Make it fresh. Keep out of reach of children.

If you have any questions, contact the County of Lambton Lambton Public Health 519 383-8331 or toll-free 1-800-667-1839.
