Meats and sausages.
Cattle, Swine, Sheep, Poultry; the livestock we use to produce meat, eggs, and milk are not genetically modified and won’t be any time soon. Genetic engineering, however, can still play a role in animal feed and in the processing of meat products like ham and sausage. To date, there are no genetically modified livestock. In the 90s, some scientists attempted to "optimize" some traits in swine and cattle by genetic engineering. They hoped to augment growth or achieve certain improvements like lowering susceptibility to disease or making milk less fattening. These projects have since died off because methods for producing transgenic animals are still in need of improvement. These projects resulted in transgenic animals that were susceptible to disease or unable to reproduce. There are also societal reservations and ethical concerns about GM livestock. The cattle, swine, sheep and poultry that we use for food are not genetically modified, and this is not expected to change any time soon.
