Many Americans consume thousands of pounds of genetically modified foods every day. Throughout the 21st century, genetic engineering has had a significant impact on new research in pharmaceutical and forensic sciences. During this period, he also revolutionized diet in America and many other countries around the world. The use of recombinant DNA biotechnology on crops and farm animals helps improve nutrition and quantity of food. However, hybrid gene-edited crops can also contain chemicals harmful to humans. Using developed biotechnology, scientists are able to inject viruses and bacteria into plant embryos to produce genetically modified crops (). The same is applied to transgenic farm animals to increase the size of the animal, thereby producing more meat. Hormones injected into the genes of farm animals accelerate their growth in preparation for marketing. People who eat genetically modified meats are susceptible to infections. Genetically modified foods affect human health by causing disease, obesity, and genetic mutations in human fetuses. Many people in the United States are dying from diseases spread by genetically modified (GMO) foods. Additionally, 5,200 people are killed by foodborne illnesses in the United States each year (Frenzen). Another 3,400 people are killed by unknown pathogens such as bacteria, toxins, viruses and prions transmitted by genetically modified foods (Frenzen). Prions are infectious protein particles, unlike a virus, contain no nucleic acid, do not trigger an immune response, and are not destroyed by extreme heat or cold(). Prions that enter the human body can impair the immune system, killing thousands of cells, triggering diseases in tissues. Many deaths caused by unknown pathogens go unrecognized... middle of paper ...... the human body experiences intercellular inflammation causing arterial damage. Finally, genetically modified foods can alter and mutate fetuses during pregnancy, particularly in the first and second trimesters. According to the Sherbrooke University Hospital Center in Quebec, the insecticide Bacillus Thuringiensis (Bt) used in corn production is a toxin that affects unborn humans. In total, 93% of the 30 pregnant women and 80% of each baby's blood contained Bt toxins (Jeffrey). Bt is a soil bacteria genetically placed in corn crop cells to help plants fight deadly pests. Monsanto and the Environmental Protection Agency (EPA) stated: “Once the toxic product is ingested, it is destroyed by the human digestive system and cannot harm the human immune system (Jeffery). » Unfortunately, traces of the toxin have been found in many fetuses whose mothers ingested Bt corns..
