Overusing antibiotics has spurred a crisis in antibiotic resistance.
Since their advent in the 1940s, it’s been no secret that the more you use antibiotics, the quicker bacteria get resistant to them.
What’s newer is the realization of the scale of antibiotic overuse, at least in agriculture. Since 2010, the FDA has collected data from pharmaceutical companies definitively showing that more than 80 percent of all U.S. antibiotics – some 29 million lbs per year– are sold for use in livestock or poultry. Ninety percent of these are put at low doses into livestock feed or water for flocks or herds, often to spur growth or economic gain and not to treat a diagnosed disease.
What’s also new is that bacteria generally now have the capability to become resistant to most if not all antibiotics quite quickly. More and more now, people are getting sick and dying from infections that no longer respond easily to antibiotics. Some, like MRSA, have become household names. Others are less known, though often no less deadly.
But most resistant infections still take place in hospitals. Inside those walls, the impact is huge: Patients with resistant infections get sicker, stay in the hospital longer, and die more frequently than do patients with non-resistant bugs. The economics are scary, too. Resistant hospital infections cost $18,000 to $29,000 per case to treat, causing a cumulative $20 billion price tag for the nation.
