Some scientists have speculated that the antibiotic resistant genes ued as markers in some transgenic plants plants could spread to disease-causing bacteria in humans. It has raised concerns about whether transgenic foods will play a part in our loss of ability to treat illnesses with antibiotic drugs. At several stages of the laboratory process, developers of transgenic crops use DNA that codes for resistance to certain antibiotics, and this DNA becomes a permanent feature of the final product although it serves no purpose beyond the laboratory stage. However, fortunately, bacteria do not regularly scavenge genes from our food.  According to a recent report in the journal Science, there is only a ‘minuscule’ chance that an antibiotic-resistant gene could ever pass from a plant to bacteria. Furthermore, many bacteria have already evolved antibiotic resistant genes.
