Finely Aged, Well Engineered
I think it's also important to point out that many fermented foods and beverages contain urethane, including bread and soy sauce; so this issue is not exclusive to wine, and these products don't have the anti-cancer properties that wine has. It would certainly be careless to begin using GE yeast that has not been safety tested to ferment these foods/beverages to reduce urethane, ameliorating one health issue only to perhaps create a different health issue.— April 6, 2008 8:36 p.m.

Transgenic just means inserting genes from a foreign species. (It doesn't have to be from an animal.) The ML01 GE yeast is transgenic, because the developer inserted a gene from a bacteria to make it. In any event, the genes being from a foreign species isn't the main issue. The main issue is the fact that the insertion of genes, any genes, is inherently disruptive and can affect the way the whole organism functions. Get your facts straight, Bruto.— April 4, 2008 4:18 p.m.

Actually, the developer of these yeasts could have done animal feeding trials to test for toxicity, the same way developers of new food additives do. And since there have been studies showing that GMOing yeasts can produce toxicity, that's exactly what he should have done. The developer of these yeasts is the lazy one (along with the FDA, which doesn't require such tests), not the writer of this article. There have also been studies showing that ethyl carbamate (when in wine) does not cause cancer in lab animals, supporting the idea that wine has other properties (i.e. resveratrol) that counteract any carcinogenic effects of ethyl carbamate. So there is no reason to take a chance on this type of GE wine yeast, healthwise or marketwise.— April 4, 2008 4:11 p.m.
