We have no idea what these effects may be, or what form the disruptions may take. We don't know because no one has studied these questions in depth, and biotech corporations are not required to conduct thorough health analyses as a precondition for putting genetically engineered products on the market. Finally, there is the question of antibiotic-resistance genes. If the sample resists an antibiotic, the gene has invaded the new organism. Manufacturers use this technique purely for convenience, cavalierly ignoring the potential health risks from breeding more virulent antibiotic-resistance germs.
Scientists know that in nature antibiotic resistance genes can pass from one organism to another.
If such genes take up residence in our bodies, many of the currently available drugs such as ampicillin, an often-used antibiotic, could become useless. Before we produce and market untested genetically altered foods, we need to conduct a complete, thorough, long-term, and independent evaluation of all of these novel organisms. And we need to label foods containing altered genes.
