Statistical errors in modern rapid BSE testing is lower than aging by dentition and has been the contention of the Japs during these long winded negotiations.
It would only make sense that Fielding would not guarantee beef to be BSE free because the USDA would be overseeing the testing.
I know that "I" would never guarantee anything done under the auspices of the USDA.
But it's what the Japs asked for. Oversight.
Think.................. the "Texas" and "Washington" cow.
