The Food and Drug Administration (FDA) has extended the comment period for an advanced notice of proposed rulemaking (ANPR) that announced potential changes to regulations governing new antimicrobial animal drug reporting. The ANPR proposed altering these regulations to incorporate the requirements of section 105 of the Animal Drug User Fee Amendments of 2008 (ADUFA 105).

FDA has requested public comments “on how best to compile and present the summary information as directed by ADUFA 105, and on alternative methods available to the Agency for obtaining additional data and information about the extent of antimicrobial drug use in food-producing animals.” FDA has extended the comment period at the request of responders until November 26, 2012.
