Could this be the future of dairy milk — allergy-free milk? Researchers in New Zealand say they have been able to genetically engineer a cow that produces allergy-free milk, spurring on hopes that the same can be done for other livestock.
What the researchers did, Reuters reports, is interfere with the RNA, or gene code, to reduce the amount of a certain protein in cow milk. The protein, beta-lactoglobulin or BLG, is what's known to cause allergic reactions. But this new and improved cow's milk has a 96 percent reduction in BLG.
