I assumed you'd use the correct language for qualitatively describing the poison, follows is a direct C+P from U.s. EPA
Group B - Probable human carcinogen. This group includes agents for which the weight of evidence of human carcinogenicity based on epidemiologic studies is "limited" and also includes agents for which the weight of evidence of carcinogenicity based on animal studies is "sufficient." The group is divided into two subgroups.
Group B1 is reserved for agents for which there is limited evidence of carcinogenicity from epidemiologic studies.
Group B2 is used for Agents for which there is "sufficient: evidence from animal studies and for which there is "inadequate evidence" or "no data" from epidemiologic studies.
However the International Agency for Research on Cancer is controverisially accused of "
susceptible to industry influence and suffers from a lack of transparency" quote WIKI.
If you think using a source that is a supporting stink tank of the organisation you propose (in this particular instance WHO) has some authority on this issue is gonna fly, then I think you'd better reassess how you present your information.
What you've done in this particular little foray is say something like "free economy policies are good for the world" and then support that by saying "the liberal party tells me so" and then further to that you declare "it must be so because The Wall St Journal and The Economist tells me so"
The fact is "vector disease control" use is being phased out - as you would well know - and it is not surprising as it is a poisonous substance that harms human health. It's use is as a last resort measure. Sort of like Hitler in WWII when he burnt and destroyed everything his troops had left as they retreated.
And nothing you can write can change those facts. No matter how hard you close your eyes and wish otherwise.
Oh and just for arguments sake - it may be cheap to manufacture, as is the case for most of the deadly crap that is manufactured by all of the chemical companies. However it's cost to human health and the wider enviroment is well known, documented, studied, expounded upon, deliberated upon and has been determined as one of the most far reaching toxilogical poisons known to humans. Hence quite logically, it is banned in nearly every country in the world. Except India and NORTH KOREA - for crissakes.
What was it you were supporting we do again with this poison???
As for the poison 1-(2,5-Dimethoxy-phenylazo)-naphthalen-2-ol that you charmingly refer to as "citrus red" it has as part of it's makeup napthalen. Look it up and see how inert that is will ya? Anyway I'll leave you to your own devices - you never know if you repeat this to yourself often enough........
