Pesticides and Human Health

Before a pesticide can be sold or used in Canada, a thorough science-based risk assessment is done.

Health Canada scientists look at people who apply pesticides and anyone else that can be exposed following its use.

This risk assessment pays special attention to more sensitive populations, including:

• pregnant woman
• infants
• the elderly

Health Canada scientists evaluate hundreds of studies on the potential human health effects and exposure routes a pesticide could take, including through diet, contact with the skin and inhalation.

Directions for use and warnings on approved pesticide labels can include:

• wearing gloves
• only using the product in well-ventilated areas and
• keeping pesticides out of reach of children and pets.

Before using a pesticide, always read the label and check for the registration number to make sure the product is authorized for use by Health Canada.
