The Controversial World of Animal Cloning

To some people, "cloning" might as well be a four-letter word. But in less than a year, it could become routine in some families—families of livestock animals, that is. Last year, the U.S. Food and Drug Administration released a preliminary report on the safety of cloned meat products, concluding that they are just as safe as regular meat. Although the agency has not yet approved the sale of meat from cloned animals or their offspring, the A-OK is likely to come sometime next year.

Clones can be thought of as identical twins, albeit with the second twin born later and only after some serious laboratory work. In other words, cloning is not the same thing as genetic modification, as it does not introduce artificial genetic changes into the animals. But for many farmers, it's still an exciting technology, because it allows them to make copies of their prized animals and then use them for breeding. Instead of having your prized cow produce, say, 5 calves in its lifetime, it can essentially produce 10, because its clone is reproducing, too.  Indeed, the general idea is not for these clones to be used for food, but rather for reproduction—you'll be far more likely to see  meat from the offspring of cloned animals on supermarket shelves than the cloned animals themselves. It's possible, however, that some meat from cloned animals will end up being sold to consumers when they can no longer reproduce, and chances are you won't know it when you eat it, as the FDA is unlikely to require special labeling for these products.

Join Wired Science as it explores the controversial world of animal cloning from various perspectives—that of farmers, scientists, and even lawyers. Learn why cloning is such an exciting new tool to some, but why others are worried that the technology—and the FDA's handling of it—could affect more than just our taste buds.

Name the cloned beef..."cleef" or "cleeph."

Your piece on cloned cows sounded like an ad for the dairy and beef industry. Suppose all milk came from one genetic type of cow and that type had an undetected genetic defect that allowed a higher level of carcinogenic pesticide to be passed in the milk. Then every drop of milk drunk by every person during his or her entire life would contribute to cancer. Besides, wasn’t it the all-knowing “scientists” of the FDA that allowed trans-fats to be added to our diet?

All milk coming from one genetic type is not going to happy. If it was, it is far more likely to happen through traditional breeding than cloning. All variation that we see (beef versus dairy cows, chihuahuas vs. german shepherds) arises from 'mutations'. The DNA in a cloned animal is not changed any more than the DNA in a traditionally bred animal. Finally, the FDA put limits on the trans-fat that was ALREADY in food. Trans-fat was not an additive that went through the FDA approval process.

Have there ever been found differences in how the biody functions in a clone as related to non cloned animals and if so what? there has been problems with cretin types of cannibalism

I found the segment to be one sided in favor of the cloning industry. Also, it neglected to address several important issues.

First, it did not address the issue of labeling. Why is the FDA, USDA and cloning industries so afraid of labeling products made from cloned animals and their progeny? If the technology is so great, shouldn't the proponents be able to convince the public that buying a steak labeled "from a clone" or from a "cutting" is OK?

Second, how does the milk production from the clones of Blackrose the champion cow compare to Blackrose? Like a champion? Or about average?

Third, have the cloning proponents held blind tastings comparing the meat from the clones of supposedly great animals with meat produced using standard fertilization techniques?
