Food grade silver solder is certified free of toxic metals. Typically cadmium is used to improve silver solder's properties, and it is toxic. Look for a NSF approval rather than just "Cadmium Free". One product is Harris Safety-Silv 56. However, I don't think that the 3A standards allow for it's use in food contact applications (gold solders only?).
Flux should have been completely cleaned off before the machinery is put in a food processing environment, so I doubt it matters. I don't think there's such a thing as a NSF approved brazing flux.
