The lawsuit comes after the FDA did not satisfy the GAP's Freedom of Information Act (FOIA) request to the agency, which sought data concerning the amount of antibiotics sold for use in food animals in 2009, classified by animal type and dosage information.

The Johns Hopkins Center for a Livable Future (CLF), an academic research center based at the Johns Hopkins Bloomberg School of Public Health, approached GAP for help obtaining these data almost two years ago. GAP made the request in February 2011, and has exhausted all other steps to get the information, short of litigation. In the end, the agency denied GAP's request, claiming that the requested data is "confidential commercial information."

"The FDA frequently claims that documents sought through the FOIA process contain 'confidential commercial information,'" said Jeff Gulley*, GAP Food & Public Health Counsel.

"When tested in court, however, these claims frequently don't hold up. This response by FDA is a violation of FOIA and a wrongful withholding of agency records."

Every year, nearly 30 million pounds of antibiotics – 80 per cent of the total antibiotics sold in the United States – are sold for use in food animals according to GAP. It is this 'misuse' of antibiotics in industrial animal agriculture that GAP says drives the development of antibiotic-resistant bacteria that have made human illnesses more dangerous and difficult to treat.

Instead of enforcing stricter regulations or providing vital information to the public on this issue, FDA has asked companies to reduce certain uses of antibiotics voluntarily, allowing rampant misuse to continue.

"How can we truly know the extent to which these drugs are causing harm if we can't even access information?" asked GAP Food Integrity Campaign Director Amanda Hitt. "The agency's job is to protect the public's health, not industry secrets."

"These data will help public health researchers decipher how the industry's antibiotic use erodes the effectiveness of these life-saving drugs," said Keeve Nachman, Ph.D., director of the Farming for the Future program at CLF, which has served as a scientific adviser to GAP on the request and lawsuit.
