Edible vaccines, as GMO foods, are in the future as well. Meat and Poultry, a business journal for meat and poultry processors, reports in a May 5, 2009 article , by Bryan Salvage, that researchers at Iowa State University are working on creating a method to install vaccines into corn crops.
"We're trying to figure out which genes from the swine influenza virus to incorporate into corn", stated Hank Harris, a researcher on the project. "If a swine flu virus breaks out, the corn could be shipped to the location to try to vaccinate animals and humans in the area quickly. . . . there is no need for extensive vaccine purification, which can be an expensive process."
This way even corn products, including corn chips and corn syrup, which is ubiquitous in processed foods, can serve as vaccination vehicles for humans while the corn itself is fed to hogs. Starting in 1996, bananas have been considered as a vaccination vehicle for developing countries. Keep in mind that this will be genetically engineered, or GMO (genetically modified organisms), so you won't know where and when it will show up on the food shelves.
Surely I'm reading this wrong? I know that it's already impossible to find corn seed that is 100% free of genetic modification (GMO) but come on!
