Fox News Senior Medical Analyst Dr. Mark Siegel urged viewers not to drink raw milk despite a push by Robert F. Kennedy Jr., President-elect Donald Trump's nominee for secretary of health and human services. Siegel made the remarks Sunday after the U.S. Department of Agriculture ordered testing of the nation's milk supply over concerns about bird flu contamination. "Raw milk is not just a danger to people who might drink," the doctor explained to Fox News host Arthel Neville.
