The word "suspected" does not appear on the report you linked. Rather it says it is a "possible" carcinogenic. Moreover

> The committee therefore reaffirmed that it is safe for a person to consume within this limit per day. For example, with a can of diet soft drink containing 200 or 300 mg of aspartame, an adult weighing 70kg would need to consume more than 9–14 cans per day to exceed the acceptable daily intake, assuming no other intake from other food sources.

This is a category that includes pickles and cell phones. The standards for this category is if some study exists somewhere suggested that, in some quantity, an item might be carcinogenic, possibly only with certain animals. The studies do not require follow-ups or repeatability. It's the lowest standard that the IARC uses.

But you just threw that in with Agent Orange. I declare this a canonical example of someone with an axe to grind.
