The WHO Notices of Concern are very similar to FDA Warning Letters. These letters are issued to a manufacturer, contract research organization or quality control laboratory by the WHO Prequalification of Medicines Programme - usually after an inspection was performed at a site where observations were made that result in concerns regarding compliance of the site with specified standards such as Good Manufacturing Practices (GMP), Good Clinical Practices (GCP) or Good Laboratory Practices (GLP).
Like with the FDA Warining Letters a Notice of Concern is published on the internet. The letters contain observations made during an inspection that are considered to be "critical" or "major" non-compliances with WHO norms and standards, that are of concern in relation to quality management or quality assurance; or "critical" or "major" non-compliances with WHO norms and standards that were not satisfactorily addressed in the response from the company to an inspection.
If WHO identifies a public health risk, appropriate additional steps are taken to advise the public. These steps may include:
