Moo for a Potential Milk Allergy Solution

A Health.com article on Monday reports that scientists in New Zealand have cloned a genetically modified, tail-less calf that produces milk containing no detectable levels of beta-lactoglobulin (BLG), the protein that is believed to trigger allergic reactions. Additionally, the hypoallergenic milk from this calf appears to be even more nutritious than regular cow’s milk, as it contains double the amount of the healthy milk proteins known as caseins.

So far, though, no genetically modified animals or animal products have been sold for food.  The nearest example is a patent-protected salmon containing genes from two other fish species that enable it to grow faster, but that fish has yet to be approved by the Food and Drug Administration.
