I’m at the Giant supermarket on York Road in Baltimore and I’m shopping with McKay Jenkins, a professor at the University of Delaware and author of a fascinating new book called Food Fight, about the battle over genetically modified organisms in the American farming and food system.
We wheel a cart down the store aisles, hunting for these organisms – called GMO’s for short. They are usually plants that have a gene from one species artificially inserted into another species. For example, scientists working for biotech companies take a type of bacteria commonly found in the dirt called Bacillus thuringiensis, remove some of its genetic material and inject it into corn. The resulting crossbreed (called Bt corn) manufactures a protein that acts as an insecticide to kill a crop-eating pest, the European corn borer.
Jenkins suddenly grabs and holds up a two liter bottle of Coke.
