Potential risks include:

Modified plants or animals may have genetic changes that are unexpected and harmful.

Modified organisms may interbreed with natural organisms and out-compete them, leading to extinction of the original organism or to other unpredictable environmental effects.

Plants may be less resistant to some pests and more susceptible to others.

What are the Health Effects?

Short-term: EPA has found glyphosate to potentially cause the following health effects when people are exposed to it at levels above the MCL for relatively short periods of time: congestion of the lungs; increased breathing rate.

Long-term: Glyphosate has the potential to cause the following effects from a lifetime exposure at levels above the MCL: kidney damage, reproductive effects.

Resistance by the USDA seems especially inconsistent, given that one branch of the agency enforces the organic rule, including the GMO prohibition, while down the hall, another rejects labels submitted by organic companies.
