The U.S. Food and Drug Administration announced Wednesday that it will ask livestock producers, drug companies and veterinarians to curb the use of antibiotics to promote growth in food-producing animals - a widespread practice that has been shown to create drug resistance in microbes. The presence of such “superbugs,” as they're sometimes called, threatens public health because if they sicken humans, they can be impossible to treat....

When the U.S. Food and Drug Administration restricted the routine use of a class of antibiotics known as cephalosporins in livestock, it picked an easy target. The agency's move is better than nothing, but nonetheless it is a reminder of the FDA's achingly slow and timid efforts to wean agriculture off the overuse of important medications. Call it a tiptoe forward after a recent giant step in the other direction and a long era of standing in one place. Eighty percent of the antibiotics used in this country are given to chicken, pigs, turkey and cattle, not because the animals are sick but to fatten them and prevent illness from sweeping through crowded pens.

Buyers of poultry products from a Cargill processing plant in Arkansas may have gotten a little something extra with their turkey burgers: a strain of antibiotic-resistant salmonella that is implicated in the death of a Sacramento man and the illness of 79 others around the country. In response, Cargill recalled 36 million pounds of turkey products last week, among the largest food recalls ever. But just because that turkey is off the shelves doesn't mean it's safe to eat undercooked poultry — or any of a host of other foods potentially contaminated by antibiotic-resistant "superbugs.

Eating cranberries to help prevent urinary tract infections is an old home remedy that has stood the test of time. But women who have recurrent urinary tract infections will find more relief from antibiotics, researchers said Monday. An estimated 30% of premenopausal women develop chronic urinary tract infections. A low dose of the antibiotic trimethoprim-sulfamethoxazole is often prescribed to women who have repeated urinary tract infections in order to prevent recurrences. Typically, however, doctors try to avoid long-term use of antibiotics because it can lead to antibiotic resistance.

A new strain of antibiotic-resistant gonorrhea should be enough to scare anyone who's playing the field without full protection. But the worries might not stop there. Like gonorrhea, chlamydia and syphilis are sexually transmitted diseases that are caused by bacteria. And anytime you have a bacterial disease, there's at least some chance that the germs could eventually find a way to outsmart antibiotics. So what are the odds that chlamydia or syphilis could turn into the next super germs?

A new strain of methicillin-resistant Staphylococcus aureus, commonly known as MRSA, has been discovered in cows and humans in the United Kingdom and elsewhere in Europe, researchers reported Thursday. The new strain disturbs researchers because it evades one of the most commonly used tests to detect MRSA, which could lead physicians to prescribe the wrong antibiotics to treat the infection. The new strain of the bacterium is still relatively rare and, so far, no deaths have been attributed to it, the team reported in the journal Lancet Infectious Diseases.

Yet another study has found stuff you don't want to eat in stuff that you eat. On April 15, scientists reported that the meat bought at supermarkets is often contaminated with Staphylococcus aureus bacteria that are resistant to antibiotics used to fight human disease. The study, published in the journal Clinical Infectious Diseases, found staph on 47% of 136 samples of beef, chicken, pork and turkey from 26 grocery stores in five U.S. cities. Of those bacteria, 96% were resistant to at least one type of antibiotic and more than half were resistant to at least three.

The new study about drug-resistant Staphylococcus aureus found in meat and poultry samples certainly sounds alarming -- such bacteria can cause serious infections in humans and can even lead to death. But consumers face a relatively small direct threat from the bacteria in food, and a few simple precautions should provide short-term peace of mind. Long-term peace of mind may take longer. It does seem possible that the meat industry is contributing to antibiotic resistance in some way. The FDA was concerned enough last year to urge that the meat industry use antibiotics only when necessary.

The problem of antibiotic-resistant bacteria has long been blamed on uninformed patients and overly permissive doctors. And as a society, we've begun to take responsibility for what our love affair with bacteria-killing drugs has wrought. We've learned (many of us) to ask for antibiotics only if we truly need them. And, if we truly need them, to take them as directed -- and to take the full course. But drug resistance may not be the sole fault of uninformed patients and overly permissive doctors.
