Despite the alarmist ending, this post does make a good point.  Removal
of antibiotic resistance markers from engineered crops is a big item on
the agenda of the agri-biotech companies.  Such products (which have the
resistance gene removed after the gene of interest is transferred in)
are becoming available.
