All baby boomers should be tested at least once for the liver-destroying hepatitis C virus, according to proposed guidelines from U.S. health officials released on Friday.
The often undiagnosed virus is contracted through contact with blood from an infected person. While the risk of infection has dropped dramatically since the early 1990s, many older adults are still at risk, according to the U.S. Centers for Disease Control and Prevention, which released the draft guidelines.
According to the CDC, one in 30 baby boomers - the generation born from 1945 through 1965 - has been infected with hepatitis C, and most do not know it.
The virus causes serious liver diseases, including liver cancer - the fastest-rising cause of cancer-related deaths - and is the leading cause of liver transplants in the United States. More than 15,000 Americans, most of them baby boomers, die each year from hepatitis C-related illness, such as cirrhosis and liver cancer.
The Food and Drug Administration called on drug companies Wednesday to help limit the use of antibiotics given to farm animals, a decades-old practice that scientists say has contributed to a surge in dangerous, drug-resistant bacteria.
Antibiotics are mixed with animal feed to help livestock, pigs and chickens put on weight and stay healthy in crowded barns. Scientists have warned that this routine use leads to the growth of antibiotic-resistant germs that can be passed to humans.
The FDA has struggled for decades with how to tackle the problem because the powerful agriculture industry says the drugs are a key part of modern meat production.
Under the new FDA guidelines, the agency recommends antibiotics be used "judiciously," or only when necessary to keep animals healthy. The agency also wants to require a veterinarian to prescribe the drugs. They can currently be purchased over-the-counter by farmers.
The draft recommendations by the FDA are not binding, and the agency is asking for drug manufacturers' cooperation to put the limits in place. Drug companies would need to adjust the labeling of their antibiotics to remove so-called production uses of the drugs. Production uses include increased weight gain and accelerated growth, which helps farmer save money by reducing feed costs. The FDA hopes drugmakers will phase out recommendations for those uses within three years.
