I've never picked up a packet of infant formula and wondered so much if it's going to kill my child that I purchase a different brand that had to be smuggled to me across the HK border.

I expect that something picked off a field and delivered to you unprocessed is probably relatively safe (although those fields are, by and large, unregulated and uninspected). Anything that has gone through an unregulated, uninspected factory? Significantly less safe.
