That looks like a FUD article, but still "Can" doesn't mean "will"!
Also, at least in Indian cooking, most spices are cooked very well, which will kill any trace of Salmonella. So, unlike the spinach and lettuce that get recalled regularly from the grocery stores, if you are using these spices for Indian recipes, you are totally fine (w.r.t salmonella).
I'd be more worried of spices that are laced with pesticides.
