According to a recently published nationwide study of grocery store meats, the next time you handle a piece of meat or poultry bought at your local supermarket there is nearly a 50 percent chance that it will be carrying drug-resistant Staphylococcus aureus (Staph). The Translational Genomics Research Institute study determined that the majority of those bacteria are likely resistant to several classes of antibiotics. Antibiotic-resistant strains of Staph are to blame for a host of illnesses, ranging from simple skin infections to life-threatening diseases, such as pneumonia and sepsis. Staph infects an estimated 500,000 patients in U.S. hospitals annually and more deathsdeaths are blamed on Methicillin-resistant Staphylococcus aureus (MRSA)infections every year than HIV/AIDS. Infectious disease experts warn the consequences of rendering antibiotics useless would be disastrous to modern medicine, which depends on antibiotics for everything from organ transplant surgeries and cancer therapies to the care of patients with trauma or battlefield injuries.
The frequency of detection of resistant bacteria on meat purchased in grocery stores is alarming. Despite this, most of the news coverage we’ve seen this week misses a key message that can be gleaned from the conclusions of the study. The study does not point directly to new or heightened food-safety risks to the consumer, rather, it serves as verification that one of human medicine’s strongest safeguards against disease is quickly losing its efficacy, in part due to inappropriate use of antibiotics in the industrial food animal production system.
