Preservation of Antibiotics for Medical Treatment Act of 2011

Preservation of Antibiotics for Medical Treatment Act of 2011 - Amends the Federal Food, Drug, and Cosmetic Act to require the Secretary of Health and Human Services (HHS) to deny an application for a new animal drug that is a critical antimicrobial animal drug unless the applicant demonstrates that there is a reasonably certainty of no harm to human health due to the development of antimicrobial resistance attributable to the nontherapeutic use of the drug. Defines "critical antimicrobial animal drug" as a drug intended for use in food-producing animals that contains specified antibiotics or other drugs used in humans to treat or prevent disease or infection caused by microorganisms.

Requires the Secretary to withdraw approval of a nontherapeutic use of such drugs in food-producing animals two years after the date of enactment of this Act unless certain safety requirements are met. Directs specified congressional committees to hold hearings on the implementation of such a withdrawal of approval.
