The 50-Year Cover-Up Killing Millions: Antibiotic Overuse in Commercial LivestockAntibiotic-resistant infections affect 2 million Americans annually, leading to the death of at least 23,000. Even more die from complications related to the infections, and the numbers are steadily growing. According to the Infectious Disease Society of America (IDSA), just one organism — methicillin resistant Staphylococcus aureus, better known as MRSA — kills more Americans each year than the combined total of emphysema, HIV/AIDS, Parkinson's disease, and homicide. A 2015 report commissioned by U.K. Prime Minister David Cameron estimates that by 2050, the annual global death toll from antibiotic-resistant disease will reach 10 million, and the global cost for treatment will be around $100 trillion. Experts have been warning about the implications of antibiotic resistance for years, but as their warnings have largely been ignored, the number of strains developing resistance to even our strongest antibiotics has been allowed to grow unabated. While overuse of antibiotics in medicine and widespread use of antibacterial household products (items containing triclosan) are part of the problem, the inappropriate use of antibiotics in farming bears the heaviest responsibility for creating the antibiotic-resistant superbug crisis of today. An estimated 80 percent of total antibiotic sales in the U.S. end up in livestock.
