I honestly think the best thing to go with is a company-based regulation system.

Start with a strict set of standards for how a product must be labeled. The government checks and ensures only that the label is correct, and that the label is deserved.

Then set standards. "A product meets this level if X"

Then a company must go through another company who gets government money on two bases. A) The number of products tested. B) The quality of the testings.

So, I as a manufacturer have a choice. A) deliver my product with no seal of quality. B) deliver my product to one of many companies who will test a batch, for a price, and will then hand off a sheet of data to the government.

Now, the company ships off it's product, and one of three things happen.

a) if the products tested show signs of failure, the company which produced the product will be fined. That fine will pay the original testing company to then re-test products that are on sale for consumers. If the two do not match, the company gets a VERY high fine.

b) the product is fine.

c) the company produced a fake label. Any citizen who turns in one of these products for sale to the government gets a small tax deduction and the company must reimburse them. The deduction is only once per year.
