We based our Safety Code 6 on all available information. That's peer-reviewed scientific literature, expert reports, information. We do not conduct a lot of the research. Some of the published results are by Health Canada science. They are peer-reviewed and done by Health Canada scientists. The bulk of the data are done by international experts around the world. We followed the procedure--the World Health Organization has a guideline--on how to develop our Safety Code 6; we used the WHO's guideline on how to develop it.
