Twelve years ago, the same restaurant chain was the first to clearly indicate which items contained genetically modified organisms. Even this is a positive and appreciated movement, a fact to consider is that the increased demand for such products has made them more expensive and difficult to obtain in the amounts that big businesses need. This could limit the possibility of a large mimic reaction in the public food industry, at least for a large time amount.
Eliminating genetically engineered ingredients is easier for Chipotle, where the entire menu uses just 68 ingredients, including salt and pepper, while one of its competitors uses 81 just to make a burrito. Previously, Chipotle even found a farmer willing to increase his production of sunflower, but the company needed more oil than he could produce. They use now canola oil, which costs more.
