News, views and tidbits plucked from the web.

An Attack on ‘Unnatural Agriculture’?.  agEconomist presents some thought-provoking arguments about why it is important to consider all options (including biotech) and the economic impacts of policy changes in our drive for sustainability.

Animal Cloning and Food:  More Than a Feeling.  The “ick factor” is a perfect example of the sentiments behind the opposition to cloning and the larger issue of genetically modified food: “It doesn’t feel right.”

Organic Food is no Middle Class Fad.   Helen Browning of the UK’s Soil Association says that preferences for organic have made it through recessions before.  I find it most interesting that she phrases her descriptions in terms of “ethical choices” and not safety, which is more how I see the reasoning behind many folks’ organic choice.

Cheap, Healthy Food.   Some good advice here, such as reminders that simple, fresh foods are both healthier and cheaper that most junk foods.  Sad that canned fruits and fish win out over fresh in the price wars, though.

Church wine bars?  From Chow.  The Church of England is contemplating opening a series of wine bars to bolster both its membership and support the wine industry.

No, Virginia, clones are not in the food supply

The first line of the article: “Milk and meat from the offspring of cloned livestock are entering the food supply”, but the headline reads “Animal Clones Are in Food Supply

I know newspapers are in the business of selling news and must attract customers to do so, but shame on the Wall Street Journal for grabbing attention with something that is sensational and not actually true.

There may well be offspring of cloned animals in the food supply.  This is not a big deal.  First of all, the FDA’s review of cloning technology has ruled that even meat and milk from cloned animals themselves is OK.  Giving a nod to public concern, they have asked for a voluntary withholding of the clones themselves from the food supply.  Cloning company,  Bovance, (and business partners ViaGen and TransOva) have put a tracking system into place for the cloned animals themselves to facilitate this.

Cloning involves taking a cell from the donor animal and inserting the part of the cell that contains the DNA into an egg (from the same species of animal) from which the DNA has been removed.  This ‘reprograms’ the donor cell into acting like a fertilized egg, and it grows and develops into a regular embryo that is genetically identical to the donor animal.  Reprogramming does not affect the chromosomes or DNA of the animal, but does affect how the DNA (genes) are used to control the development of the embryo.

But as for the offspring of clones? Because the DNA is not changed, offspring of clones are in no way different than any other animals. Even though there is no scientific reason to expect them to be different, there have been studies done on offspring of clones (all the way through production of milk and meat, and sure enough–no differences!

There may well be an insignificant number of offspring of clones that have been harvested.  Based on the facts, I fail to see why we should care. As far as food safety goes, this is really a non-issue.
