Is your product irradiated at any point?

Yeah, when the garlic is in the sun it is irradiated. As for whether the product is irradiated (with something like ultraviolet light) to disinfect it... I do not know. However, it does not matter. It is not like the "radiation" stays in it and makes it somehow harmful. It would be much better than chemical disinfectants. The question is as irrelevant as asking whether it was ever harvested on a Tuesday.... because that's the unlucky day.

Are there any fillers, anti caking ingredients, and other ingredients in it that are not required by law to be disclosed?

It’s a single source pure turmeric powder.
