GE foods remove consumer choice- because products differ depending upon people’s level of many GE crops are not separate from non-GE foods education and interpretations of what each of these in the food system and consumers have been denied terms mean.

Biopiracy- use of intellectual property system to over our right to “play God” (meaning his creations), legitimize the exclusive ownership and control over as well as the introduction of foreign material into biological resources, products and processes that foods that are abstained from for religious reasons. have been used over centuries in non-industrialized culture. ❖ These issues are increasingly important to consider 3. Loss of Farmers rights- GMO agriculture has led to as the number of GMOs continues to increase due to superweeds and superpest that are difficult for improved laboratory techniques and tools for farmers to manage.

Among the topics being the field. debated is the language to be used on the labels and what percentage of GMO ingredients a product must contain for a label to be mandatory. ❖ Last February 2019, in its “Draft Guidelines on Labeling of Prepackaged Foods Derived from or Containing Ingredients from Modern Biotechnology,” the Philippine Food and Drug Administration (PFDA) indicated that it would not require labeling for GE packaged foods because it has no difference with conventional foods, not carcinogenic and has been proven safe for human health under numerous test. There are at least 34 gene insertion processes involving genetically modified food that have been approved for commercial release in the philippines. Corns Soybeans MT2-B | 2
