While the FDA is responsible for protecting and promoting public health through the control and supervision of food safety, the agency holds the position that "the use of genetic engineering in the production of food does not present any safety concerns for such foods as a class", and , as there is "an absence of reliable data indicating safety concerns" with GMO foods as a class, voiced no opposition for USDA having the responsibility of regulating GMO food labeling.[12] The agency commented that the bill has language that may allow GMO material to escape labeling: the bill requires labeling if the food contains "genetic material", but that may exempt secondary products like oil, starches, sweeteners, or proteins derived from GMO substrates.[12] The agency questioned the specificity of the definition of bioengineered food when it would not apply to GMOs that could also be achieved by "conventional breeding".[12] The FDA has also voiced some concerns about food information being presented in electronic codes.[12]
