Mastitis is the inflammation and infection of breast tissue. A bacterium, staph aureus, is the most common cause, but other bacteria cause it as well. Mastitis occurs in domestic animals as well as in human beings, especially cows, since milk from the infected udders of livestock may enter the food supply and pose a public health risk. It has a tremendous economic importance for the dairy industry, to the tune of two billion dollars a year.
Molecular biologist John Lippolis, in the Ruminant Diseases and Immunology Research Unit of the U.S. Department of Agriculture has discovered that simple vitamin D, injected directly into a cow’s infected breast, effectively treats the disease.
The importance of this should not be underestimated. Perhaps they will soon discover that vitamin D added to cow’s feed does the same thing. If so, we may all be getting a little more vitamin D in our hamburger. This is one strategy that the government is looking into fortifying food with vitamin D.
