Cancer Society 
Cosmetic Pesticide Use

The Canadian Cancer Society has taken a position on cosmetic pesticide use. Speaking for the society, CEO Julie White wrote in the Guelph Mercury, "We accept convincing evidence that some commonly-used pesticides cause cancer. We have called for a ban on the ornamental use of chemicals that have been identified by the International Agency for Research on Cancer as known, probable or possible carcinogens. Ornamental use means using carcinogenic chemical pesticides in the home, on gardens and lawns, and on recreational facilities such as parks and golf courses.

"The Canadian Cancer Society uses both the precautionary principle and the best available, high quality science to develop our cancer prevention and risk reduction messages. In the absence of definitive research, and without countervailing health benefits, the precautionary principle prevails. 

And so, if an activity such as the ornamental use of pesticides raises even the threat of harm to human health or the environment, precautionary measures should be taken, even if some cause and effect relationships are not fully established scientifically."
