Are there long-term studies on the consumption of food from clones?
Cloning doesnt put any new substances into an animal, so theres no new substance to test. Feeding milk or meat from clones to lab animals as part of a regular diet wouldnt let us tell whether any negative outcomes observed were due to the food from clones or from something else the lab animals came across. It isnt possible to have someone (or even lab animals) eat only meat or drink only milk. Doing so would not provide a healthful diet and would likely cause illness. Food scientists, toxicologists, and regulators have faced this problem before and decided that long term feeding trials of whole foods dont give meaningful results.
