Napthol and Azo dyes for certain have carcinogenic ingredients -

"As early as 1895 increased rates in bladder cancer were observed in  
workers involved in dye manufacturing"

"Is it safe to eat or breathe fiber reactive dyes?

No!  While the toxicity of the Procion MX dyes is low enough that  
they are generally considered 'non-toxic', they have not been tested  
for human consumption. It is likely that consuming significant  
amounts of some of the Procion MX dyes would increase one's risk of  
cancer, just as with a number of colorings that were formerly allowed  
to be used in foods, but later found to be mildly carcinogenic and  
thus banned for this use."
   very informative site if you are working with dyes or thinking  
about doing so.

Better safe than sorry.
