I will try. I am not a risk assessor; I manage risk assessors in Health Canada. I would like to give the message that anybody I've encountered at Health Canada doing risk assessment for human health takes a very protective and conservative approach. The basic policy undertaken is that we would rather over-protect than under-protect. So our decisions are geared to try to make sure we're protecting.
There are a couple of mechanisms that might give you some assurances about testing carried out by industry. There is data that an industry laboratory may submit, but the risk assessment process in Health Canada in my area doesn't usually benefit from a practice called “good laboratory practice”, which builds on what Mr. Moffet talked about, using methodology that's been well-validated and accepted. During the carrying out of the generation of the data, there are also inspections by outside auditors to determine whether the process you're supposed to be following--the test method you're using--has been followed.
