One of the most serious issues confronting the global food system is the wastage of approximately one-third of food at various points throughout the supply chain due to environmental and economic factors. Declines in production and food quality deterioration are concerns due to less awareness of the farming community and end users about the advanced technologies. Therefore, scientists face to develop cutting-edge technology to solve these problems and feed the bulging population to prevent starvation. Genetic engineering (GE) techniques can aid in several contexts to boost crop yields and quality. Biotechnology, genetic modification, and recombinant (r) deoxyribonucleic acid (DNA) technologies are significantly beneficial in pursuing chief progress in food production and supply. This latest literature review illustrates the recent advances in GE, their sources, current trends, and future. GE foods from animals, microbes, and crop plants have altered DNA and introduced modified genetic characteristics. Genetically modified organisms (GMOs) are vital parts of the industrial food system, and most packaged foods contain GMO ingredients that received engineering for resistance to pesticides and herbicides. Several issues raise red flags concerning GMOs, including safety, effects on the environment, and ineffective usage of pesticides. Many people are anxious about GMOs; however, most do not understand the problems. [ABSTRACT FROM AUTHOR]
