Due to some of the environmental changes that have occurred our food supply may be severely threatened. Over the past several decades "bioengineered foods" have been developed.

Good luck. Here are responses to your questions.

What are bioengineered foods?

Genetically modified (GM) foods are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering, using a process of either Cisgenesis or Transgenesis. These techniques are much more precise than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms include selective breeding (plant breeding and animal breeding), and somaclonal variation.
GM foods were first put on the market in the early 1990s. Typically, genetically modified foods are transgenic plant products: soybean, corn, canola, and cotton seed oil. But animal products have also been developed. In 2006 a pig was controversially engineered to produce omega-3 fatty acids through the expression of a roundworm gene produced. Researchers have also developed a genetically-modified breed of pigs that are able to absorb plant phosphorus more efficiently, and as a consequence the phosphorus content of their manure is reduced by as much as 60%.
Critics have objected to GM foods on several grounds, including perceived safety issues, ecological concerns, and economic concerns raised by the fact that these organisms are subject to intellectual property law

Food is traded between states as well as globally. Global food trade is extremely important to all countries. But how many of you know where the food on your tables comes from? Many scientists wonder if we will be able to continue to grow enough food for a growing population. One of the most widely debated issues right now is genetically modified organisms (GMO's). Genetic engineering allows for desired traits to be put into plants. Genetically modified foods have been available in this country for more than a decade. Most of you are probably eating GMOs without even knowing it. More than 75% of the products on the super market shelves contain a component that is a GMO.
