Even food being mfg in the US is using raw materials from China.
When a company chooses to save a penny by buying from China, they better make sure these are untainted. I have my doubts with the volume of trade and distributors not clearly indicating the country of origin that these issues will spread.
Another excellent point that's often overlooked. Hence the need for a website that says where everything originates, though I don't know who would embark on such a massive undertaking, or how they would make money at it. It's sorely needed.
