Cloned Meat: Is Dolly for Dinner?
Company That Tracks Cloned Meat Wants to Pull the Wool From Your Eyes

Feb. 14, 2008 (Boston) -- Many consumers want meat produced by cloning to be easily identified as such. Now a company
based in Ireland is promoting its system for tracing the meat of any cloned
animal wherever it may go in the food supply. For this tracing system to work,
however, the unique DNA profiles of clones must be publicly available.
Patrick Cunningham, PhD, chief science adviser to the Irish government and a
founding executive of the company IdentiGEN, advocated for open access to
cloned animal DNA at this week's annual meeting of the American Association for
the Advancement of Science in Boston. Major chain stores and meat packers in
the United States, he says, want to offer discerning shoppers certifiably
"clone free" meat products. "They should have a right to do
that," he says.
Cunningham says companies that clone animals should keep a library of
"snips" of their DNA. That way, anyone wishing to screen for traces of
cloned meat in food could ask a company like his to compare product samples
with the genetic profiles of clones on file. Big retailers and food producers
in Ireland and the U.K. now use IdentiGEN to certify other qualities of meat
products, as well as to assist in safety recalls.
In the United States, Kroger, Safeway, Dean Foods, and Whole Foods have
considered marketing "no clone" meat.
Mark Walton, PhD, president of ViaGen, a company that clones animals for use
in agriculture, says he doesn't think a DNA tracing system is justified.
"It's hard to imagine a scientific reason or a health reason that you would
need to follow animals at all," he says.
FDA: Cloned Meat Safe
The FDA has repeatedly assured American consumers that meat produced by
cloning is safe to eat, and the agency says it will not require special
labeling on food containing products of cloned animals or their offspring sold
in the United States. Europe's food safety agency has reached the same

The use of cloning for producing food is often misunderstood. For one thing,
it probably won't be used to make thousands of copies of an animal expressly
for slaughter. A cloned cow now costs about $13,500, compared with the market
price of about $1,000 for a normal steer.
"Cloning technology is in fact a breeding technology," Walton
The process is called "somatic cell nuclear transfer," which is how
the famous sheep "Dolly" was cloned in 1996. Producers use this process
to clone highly desirable breeding animals. For decades, farmers have routinely
ordered semen from choice male animals to artificially inseminate their herds,
but one prize stud can only produce so much semen. In theory, 10, 20, 100, or
more clones of him increase the yield of his genetic material that many
