Thank you, Mr. Chairman. There is testing that is done on various animals. The safe levels are different and are recorded by the various scientists who actually do the testing. I would not be able to quote the exact detail, but I can commit to having the safe levels communicated. It also involves how it is digested and whether the nutritious effect of the food that is being digested is often weighed by the potential for contamination. There has to be a weighing of the benefits versus the risk.

A lot of that information has been published through the Department of Health and Social Services with the federal government in various research documents that we have produced over the years. Thank you.
