Source data (openFDA JSON) About FDA enforcement reports

FDA records come from the openFDA drug enforcement-report dataset — the agency's full weekly enforcement list. Most entries are not issued as consumer press releases, so they won't appear on fda.gov/recalls or in a web search. The source record link above resolves this exact recall by its number.
