new YORK (Reuters) – A federal judge ordered to the

U.S. regulators to withdraw the authorization of use

of common antibiotics in feedingstuffs, the mention

concern that excessive use can put in

risk human health by creating “superbacterias” resistant to

medication.

The judge Theodore Katz ordered Thursday the Administration

food and United States drugs (FDA by its acronym

in English) to begin procedures to put an end to the

authorization unless the producers of medicines

can generate evidence that their use is safe.

If the laboratories can not prove that inofensividad,

the FDA must withdraw approval for non-medical uses of

these drugs, the judge ruled.

The Agency had begun with these procedures in 1997,

driven by concerns about the widespread use in the

food for the cattle of certain antibiotics, particularly

tetracycline and penicillin, more common. But that process never

was completed and the authorization remains in effect.

“in these years has been growing scientific evidence of the

“

risks to the health of the expanded of antibiotics use

in cattle, and there is no evidence that the FDA has changed its

position on that isn’t shown that these uses are

“

insurance”, wrote Katz.

The demand was made by environmental groups and

defence of public health.

The plaintiffs argued that use common antibiotics

in the cattle feed contributed to rapid growth

of bacteria resistant to drugs in animals as

human.

Antibiotic-resistant infections cost to the

Americans over 20 billion dollars annually,

the plaintiffs, who cited a 2009 study indicated

the Alliance for the prudent use of antibiotics and Hospital

the Cook County.

In his letter, Katz ordered the FDA move forward with the process

initiated in 1977 but only formally abandoned in December

passed. The FDA said that the procedures were

out-of-date and which purported to follow other strategies

regulatory to deal with problems of security

food.

“the FDA has not issued any statement since the launch

“

(the news) in 1977 that undermines the original findings of that

“

drugs have not proven to be safe”, wrote Katz.

The FDA could not be immediately contacted to carry out

comments in this regard.
