Ag-gag laws are anti-whistleblower laws that apply within the agriculture industry. Popularized by Mark Bittman in an April 2011 The New York Times column (but used long before then by advocates), the term ag-gag typically refers to state laws in the United States of America that forbid undercover filming or photography of activity on farms without the consent of their owner—particularly targeting whistleblowers of animal rights abuses at these facilities.
