*Potential Allergens

When a trait from an allergenic source is introduced to a nonallergenic environment, there is a potential for allergen transfer. No allergic effects have been found for current GE crops on the market.

*Potential Outcrossing

Occurs when conventional crops and GE crops are mixed unintentionally. Outcrossing may present challenges to effectively monitoring the use of biotechnology.

*Potential Gene Transfer

Possibility for the transfer of genes that could harm consumer health (i.e antibiotic resistance). Use of technology that reduces the use of antibiotic resistant genes is encouraged. 

*"GMO" Labeling

Concerns stem from arguments over a consumer's "right to know" and the effects that increased regulations will have on producers.

*Potential Threat to Biodiversity

Evidence shows that GE crops have little to no direct effect  on ecosystems...However, some reports suggest that GE crops may be indirectly linked to a decline in certain species' populations.

*Ethical Matters

Experts continue to debate the scientific morals behind preserving the environment, saving millions of lives, and "unnaturally altering nature." Many ethical concerns are evaluated on a case by case basis.

*"Super Pests"

Some reports indicate that certain pests (insects, weeds, parasites, etc) have developed resistance to current control methods. Which in turn, promotes the increased use of the same or different control methods.
