Antibiotics in livestock affect humans, USDA testifies

There is a clear link between the use of antibiotics in livestock and drug resistance in humans, President Barack Obama’s administration says, a position sharply at odds with agribusiness interests.

In testimony to a House committee on Wednesday, even the Agriculture Department, which livestock producers have traditionally relied on to advocate for their interests, backed the idea of a link between animal use of antibiotics and human health.

The Agriculture Department “believes that it is likely that the use of antimicrobials in animal agriculture does lead to some cases of antimicrobial resistance among humans and in animals themselves,” said John Clifford, the USDA chief veterinarian.

The Food and Drug Administration, which regulates antibiotics in animals and humans, has recently proposed to end the use of many drugs as growth promoters in hogs and other livestock. Only antibiotics such as ionophores that have no human use would be permitted to speed animals’ growth. The FDA has set a schedule for phasing out the drugs’ use or proposed specific restrictions.

Officials said the ban is needed to ensure that the drugs remain useful in human medicine.

Clifford was joined by officials from the FDA and the Centers for Disease Control and Prevention in telling a House Energy and Commerce subcommittee that there was evidence of a link between animal uses of antimicrobials and human health.

At an earlier hearing, government health experts said U.S. data on the linkage was lacking. But Wednesday, administration officials tried to make a closer connection. Studies of salmonella, for example, have shown that giving antibiotics to livestock causes bacteria in the animals to develop resistance and that resistant bacteria in food can be transmitted to people, said Ali Khan, the assistant surgeon general.

Agribusiness representatives and their allies on the committee said more research is needed.

“So far there’s nothing that links use in animals to a buildup of resistance in humans,” said Rep. John Shimkus, R-Ill.

A representative of the drug makers, Richard Carnevale of the Animal Health Institute, said there is “no unequivocal evidence” of a connection.

A committee member, Rep. Bruce Braley, D-Ia., said there were “very real production concerns” with restricting the drugs. He said “this is an issue that demands thoughtful careful consideration of all points of view.”

Apparently this summer has been one of the hotest Ottawa summers on record. While the cows are grazing and chewing their cud in the cool grass outside, some of the Grazing Days office work has been taking place in an overheated indoor appartment… until now…

The Grazing Days office is moving to a more spacious house with patio and backyard access! Oh Yeah!

The new Grazing Days address is now:
166 Glebe Ave.
Ottawa, Ontario, K1S 2C5
