Re: GM DNA in the human digestive tract

Hi Steve,
Essentially all of the GM crops presently being  sold contain  an
antibiotic resistance  gene (called a selectable marker). Efforts have
been made to create selectable markers that can be deleted from the
original plant selected but these are still on the drawing board or in
some cases a herbicide tolerance gene  has been used as a selectable
marker but  those stains are not yet commonly  used in commercial
crops.The removable selectable markers depend on  genetic technology
related to terminator. Your information  on  antibiotic selectable
markers  making up less than 20% of commercial GM crops  is easily
refuted by information on regulation documents  from USDA,EPA and the
Canadian food inspection agency. Sincerely, Joe
