''Federal legislation was re-introduced on Tuesday to curb the use by industrial livestock farms of massive amounts of antibiotics important in human medicine.
'It's not that they're sick,' Rep. Louise Slaughter, D-New York, said of the animals being fed antibiotics in concentrated animal feeding operations (CAFOs). "It's to compensate for unsanitary conditions, crowded conditions, and to promote weight gain."
The majority of antibiotics sold in the United States are given to CAFO animals, Slaughter said during a teleconference on the Preservation of Antibiotics for Medical Treatment Act.
The concern of the American Medical Association and three hundred other organizations that support the legislation, according to Slaughter, is that feeding antibiotics to animals contributes to a dramatic rise in antibiotic-resistant infections in people.
Shelley A. Hearne, managing director of the Pew Charitable Trusts' health and human services program, said physicians warn patients against taking antibiotics if they're not sick, "but this is actually the practice going on in farms."
Steve Ells, founder of Chipotle Mexican Grill, which serves antibiotic-free pork raised in pastures or deeply bedded pens, said antibiotics should be used only for sick people and sick animals.
Non-therapeutic use of antibiotics should not be viewed as 'a prerequisite for life on the farm' but as "a threat to life itself," Ells said.
The practice has been banned by the European Union.
U.S. Rep. Mike Pence's position was unavailable on Tuesday. 'The congressman will be sure to take a look at Rep. Slaughter's legislation once it is formally introduced and brought before the House in the 111th Congress,' spokesman Daniel Son said.
The Star Press interviewed veterinarian Jeff Harker, then president of the Indiana Pork Producers Association, about antibiotics at the Midwest Pork Conference in September.
'In most cases, the antibiotics break down into inert forms after they go through the digestive systems of the pig and the manure storage process and are discharged onto the field,' Harker said. 'They have mutated or changed into inert form.'
'The soil contains many bacteria. There is a slight concern there about possibly some antibiotics reaching the field and creating a bacteria that might be resistant, that might develop resistance to it, but it's such a minimal chance of risk that we usually don't even get concerned about it.'
He asked: 'Would you rather have a one-in-a-million possibility of infection with antibiotic resistant bacteria, or do you want diarrhea three days a year from a food borne illness because you ate meat from an animal that wasn't fed antibiotics?'
Harker said that sub-therapeutic antibiotics were banned in Denmark 10 years ago.
'They found when they banned prevention antibiotics, the level of treatment antibiotics went through the roof,' he said. 'And they found just as many resistant bacteria when they banned sub-therapeutic antibiotics. So it's not as simple as we think.''
