I don't think regulation is the answer. We need very heavy penalties for those who do not test their ingredients/products purchased. Ignorance is no plea when it comes to our food supply. The fine needs to be so high the incentive is to police themselves if they want to sell their products in or to the U.S.
Industry here in the US is heavily weighed down by regulation by agencies like the FDA. It stifles US competitiveness and costs jobs. The way they shake down US companies and then give the Chinese a pass just boils me
