Scientists have discovered a third instance of a bacteria resistant to one of the strongest antibiotics available, raising concerns about the spread of so-called "superbugs."
Researchers found E. coli bacteria resistant to the antibiotic colistin in a pig at an Illinois slaughterhouse, a U.S. Department of Agriculture spokesperson said earlier this week. Colistin is often used against bacteria that fail to respond to more common antibiotics.
Consumer demand, public health concerns and new federal rules all are driving the pork industry away from routine use of certain antibiotics. Booths at the World Pork Expo, a three-day event underway this week at the State Fairgrounds in Des Moines, reflect the move away from antibiotics.
On a cold windy morning, Kelly Nissen feeds the cows at the Iowa State University Beef Nutrition Farm north of Ames. Far from just tossing hay, he weighs out specific rations and carefully delivers them to numbered feed bunks.
"When you're feeding, you’re always double-checking yourself to make sure it's going in the right lot," Nissen says.
Some of the most important medicines doctors prescribe to fight infections are losing effectiveness and the Obama Administration is calling on farmers to help turn the tide against antibiotic-resistant bacteria. A recent report by the president's advisors on antibiotic resistance charts some progress but also left some critics urging for more immediate action.
University of Iowa clinical associate professor in the Department of Epidemiology, Michael Pentella, joined host Ben Kieffer on the talk show "River to River" to talk about the state of antibiotic resistance in the country. The discussion focused on tuberculosis, since ISU researchers are currently studying an extensively antibiotic resistant strain of the disease that is growing in parts of the world.
