What is in this article?:
- Antibiotics court order based on 35-year-old events
- Issued notices in 1977
- Did not establish safety
- For more than 30 years, the FDA has taken the position that the widespread use of certain antibiotics in livestock for purposes other than disease treatment poses a threat to health.
- Though the FDA has continued research on antibiotic resistance as the result of the subtherapeutic use in animal feeds, it did not rescind the notices for the opportunity for hearing and has not concluded that their use is safe.
Issued notices in 1977
“In 1977, the FDA issued notices announcing its intent to withdraw approval of the use of certain antibiotics in livestock for the purposes of growth promotion and feed efficiency, which the agency had found had not been proven to be safe.
“The FDA issued the notices pursuant to [the appropriate statutes]…. Although the notices were properly promulgated and over twenty drug sponsors requested hearings on the matter, the FDA never held hearings or took any further action on the proposed withdrawals.
“In the intervening years, the scientific evidence of the risks to human health from the widespread use of antibiotics in livestock has grown, and there is no evidence that the FDA has changed its position that such uses are not shown to be safe.
“In May 2011, after the FDA failed to respond to two Citizen Petitions urging the agency to follow through with the 1977 notices, Plaintiffs filed this action seeking a court order compelling the FDA to complete the withdrawal proceedings for antibiotics included in the 1977 notices.”
After reviewing the history of the “use of antibiotics in food-producing animals, “Katz turns to the antibiotics that are the subject of the NRDC lawsuit: penicillin and two forms of tetracycline. In the 1950’s the FDA properly authorized the use of these antibiotics in animals. “Since that time, penicillin has been used to promote growth in chickens turkeys and swine and tetracyclines have been used to promote growth in chickens, turkey, swine, cattle, and sheep.
“In the mid-1960s, the FDA became concerned that the long-term use of antibiotics, including penicillin and tetracyclines, in food-producing animals might pose threats to human and animal health. As a result in 1970, the agency convened a task force to study the risks associated with the use of antibiotics in animal feed.”
“In 1972, the task force published its findings, concluding that: (1) the use of antibiotics in animal feed, especially at doses lower than those necessary to prevent or treat disease, favors the development of antibiotic-resistant bacteria; (2) animals receiving antibiotics in their feed may serve as a reservoir of antibiotic pathogens, which can produce human infections; (3) the prevalence of bacteria carrying transferrable resistant genes for multiple antibiotics had increased in animals, and the increase was related to the use of antibiotics; (4) antibiotic-resistant bacteria had been found on meat and meat products; and (5) the prevalence of antibiotic resistant bacteria in humans had increased….
The task force made several recommendations, including that (1) antibiotics used in human medicine be prohibited from use in animal feed unless they met safety criteria established by the FDA, and (2) several specific drugs, including penicillin and tetracyclines, be reserved for therapeutic use unless they met safety criteria for non-therapeutic use….
“In response to the findings of the task force, the FDA (in this article we use “FDA” to designate the Food and Drug Administration or any of its units), in 1973, issued a regulation providing that the agency would propose to withdraw approval of all subtherapeutic uses of antibiotics in animal feed unless drug sponsors and other interested parties submitted data within the next two years “which resolve[d] conclusively the issues concerning (the drugs’) safety to man and animals…under specific criteria” established by the FDA.”
