Agman, 'Is it not the postion of R- Calf members that imported beef is unsafe. If so, why less tracking on "UNKNOWN"? Would they not have a price advantage through less tracking cost?"

Feel free to post a quote from R-CALF about the safety of imported beef if you have one.

There would be less tracking on "unknown", for obvious reasons - if you traced it, it would then be known!  I'm not too worried about their pricing advantage.  A good checkoff-funded campaign on buying US BEEF could very well negate that.
