Making claims for differences between "residues" in organic vs conventionally grown products of any kind should have to be documented, IMO.
Re. the "excessive" use of antibiotics......what is definition of "excessive"?
How much antibiotic gets into streams, groundwater, etc. due to soaps and other consumer products? How much goes through patients taking them (unnecessarily or not) and ends up in the water? How does all that compare with antibiotics fed to animals to prevent diseases? Until we have answers to these questions and more, how can we know what actions need to be taken.
Re. hormones.....same deal.
It just seems to me that with tests able to detect infinitesimal levels of possible residues, it should be possible to take the emotion and hype of the anti-meat people out of this equation and use sound science as the basis for decisions.
