While drug-resistant bacteria, such as E. coli, are common in the industrial broiler chicken environment, this is the first U.S. research to show exposure occurring at a high level among industrial poultry workers. The results are published in the December, 2007, edition of Environmental Health Perspectives.
“The use of antimicrobials in industrial food production has been going on for over 50 years in the United States,” said the study’s lead author, Lance B. Price, who serves on the research faculty at the Johns Hopkins School of Medicine, Division of Infectious Disease, and is a scientific advisor to the Johns Hopkins Center for a Livable Future. “Some estimates indicate that well over half of the antimicrobial drugs produced in the United States are used in food animal production. In the U.S. alone, over nine billion food animals are produced annually.”
The study was conducted with poultry workers and community residents in the eastern shore regions of Maryland and Virginia, and it confirms similar studies in Europe showing that poultry farmers and workers are at risk of exposure to drug resistant E. coli bacteria. The Maryland and Virginia regions on the Delmarva Peninsula are among the top broiler chicken producing regions in the U.S., producing more than 600 million chickens annually.
In the study, researchers conducted in-depth analyses of 49 study participants, 16 working within the poultry industry and 33 community residents. Stool samples from the participants were tested for resistance to the antimicrobials ampicillin, ciprofloxacin, ceftriazone, gentamicin and tetracycline. Findings showed that poultry workers had 32 times greater odds of being colonized with gentamicin-resistant E. coli than other members of the community.
“One of the major implications of this study is to underscore the importance of the non-hospital environment in the origin of drug resistant infections,” said Ellen K. Silbergeld, PhD, senior author of the study.
Price, PhD, and other researchers note that as food animal production shifted from the independent farmer to large-scale, industrialized operations, the use of antimicrobials in feeds intended to stimulate growth has increased. Currently 16 different antimicrobial drugs are approved for use in U.S. poultry production with gentamicin reported to be the most widely used.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
