Well, worst case scenario is the (very rare) chance of getting contaminated product through international spice adulteration and counterfeiting - and that contamination giving you some unpleasant food poisoning that gives you kidney disease leading you to either need a transplant or to live on dialysis for years.
I just did a web search for contaminated spoces and there are some recent US cases of imported turmeric that was high in lead. So worst case is that you very slowly give yourself lead poisoning.

True enough. Though as far as contamination goes...I'm far more worried about other products. The spices are all a local brand - one in which I've got reasonable trust. Things like olive oil though...fake olive oil seems to be par for the course. That freaks me out 100x more than "fake" parsley.
Or you can buy turmeric + BioPerine from a reputable US based company with extensive metal testing to make sure there's no contamination, like DrVita (where I happen to be employed and can confirm an obsession with testing for heavy metals)
