The Farm & Ranch guide links the tainted pet food scandal with country of origin labeling:

Country of Origin Labeling passed several years ago but USDA’s Agricultural Marketing Service has yet to implement the law.

Now, it looks like the United States may accept this legislation. Unfortunately, that acceptance may come about because of what happened to some family pets.

Country of Origin Labeling, or COOL, is an initiative of the 2002 farm bill. It requires country of origin labeling for beef, lamb, pork, fish, perishable ag products and peanuts.

President Bush signed a public law on Jan. 27, 2004, that called for a delay in implementing COOL for all commodities except wild and farm-raised fish and shellfish until Sept. 30, 2006.

Then on Nov. 10, 2005, the President signed another public law delaying the implementation until Sept. 30, 2008.
