Considering that the corn (Zea mays) GA21 belongs to  a  well characterized  species with a solid background of safety for human consumption and that the mepsps  gene introduced in this  variety codifies a protein that is ubiquitous in nature, present in plants, fungi and microorganisms participating in the alimentary diet of humans and animals.
Considering that the genic construct used to insert the gene in corn resulted from the stable  insertion of  a functional copy of mepsps, which granted tolerance to the  glyphosate herbicide.
Considering that centesimal composition data failed to  identify significant differences between the genetically modified and conventional varieties, suggesting nutritional equivalence between them.
Considering, in addition, that:
1. Corn is the species that reached  the highest domestication level among cultivated plants, and is  unable to survive  in nature with no human intervention.
2. In Brazil, there are no wild species  with which corn may intercross, since  the closest wild corn species is teosinte, found only in Mexico and in some Central America locations, where it may cross  with corn cultivated in production fields.
3. The mEPSPS protein was detected in low  levels in tissues analyzed  and displayed great susceptibility to digestion in simulated gastric fluids, lacking acute toxicity in mammals and similarity with known allergens.
4. The genetic modification introduced in GA21 event did not result in important differences  of chemical composition regarding nutrients, which are  within the normal variation range found between conventional varieties.
5 The DNA molecule is a natural  food component and there is no evidence that this molecule may have adverse effect to humans when ingested in food in acceptable amounts (no direct toxic  effect).
6. There is no evidence that  intact plant genes may be transferred and functionally integrated to the genome of human or other mammals exposed  to this DNA or to food produced with such elements(15).
7. The applicant  answered all questions stipulated by CTNBio Regulatory Instruction no. 20 and that no topic  indicated that this corn may have adverse effect in human and animal food.
8. The likelihood of a transgenic plant to change into a  weed species, as well as the crossing  of GA21 corn with other corn plants originating a pest is negligible.
9. The mEPSPS protein is common  to plants, fungi and microorganisms and  the  exposure of living organisms and the environment to this protein is an event that occurs  abundantly in nature without resulting significant risk to soil microbiota.
10. The coexistence between cultivars of conventional corn (either  cultivated or creole) and transgenic corn cultivars is possible from the agronomic viewpoint, under the provisions of CTNBio Regulatory Resolution no. 4.
11. Annex III  of the Cartagena Protocol on Biosafety (Decree  no. 5,705, of February 16, 2006) provides that risks associated to modified living organisms or to products derived therefrom, to  wit, improved materials  originated from a modified living  organism containing new detectable combinations of replicable genetic material obtained by modern biotechnology shall  be considered in the  context of  the risks posed by  the unmodified receptors in kindred organisms in the probable receiving environment.
