WHO Medical Product Alerts: How a Research Buyer Reads Them

What is a WHO Medical Product Alert, how is one triggered, and how should an African buyer use the list without over-reading it?

A WHO Medical Product Alert is a public notice that a specific product, usually identified by name, manufacturer and lot, has been found to be falsified, substandard or contaminated somewhere in the world, with an invitation to national authorities and others to look out for it. The alerts sit on a single WHO page, grouped by year ^[1].

A research buyer can use the list in one narrow way: as a cross-check on a named lot that has already been received. It should not be used as a certificate that anything absent from it is sound. The system is built for medicines and diagnostics moving through regulated supply chains, and the research-materials trade mostly sits outside it.

What the list is and where it lives

The WHO list is titled the Full list of WHO Medical Product Alerts. As read on 10 October 2026, entries run in reverse chronological order from 2026 back to 2013, each with a date, a label and a title that links to the full notice ^[1]. The 2026 section showed four entries and 2025 showed eight at that reading. The list also carries entries labelled Information Notices, which address users of in vitro diagnostic devices.

The number of entries per year is small. That is not evidence that few falsified products circulate. It reflects the threshold for publication: an alert is issued when WHO judges that the information will help national authorities and the public, and when the report has been verified.

The surveillance chain behind an alert

Alerts originate in the WHO Global Surveillance and Monitoring System, usually shortened to GSMS ^[2]. National regulatory authorities nominate focal points, who send reports of suspected substandard and falsified products to WHO. WHO assesses the reports, can request further information, and may publish an alert or circulate a rapid alert to focal points ^[3].

South Africa's regulator describes the same chain from the national side: it shares and receives alerts about falsified and substandard medicines with WHO and other regulators through its focal person, and passes information to WHO through the GSMS ^[6]. The practical consequence is that a published alert depends on a national authority having noticed a problem, reported it and had it verified.

Anatomy of an alert

Alerts follow a numbered format, for example Medical Product Alert N°2/2020, which concerned falsified HIV rapid diagnostic tests ^[4]. Read the notice itself rather than its headline. What matters to a buyer is the following.

Match on lot and expiry, not on name. A name match without a lot match means nothing. A lot match without a name match means nothing either. Only the combination is evidence.

What the list rarely covers

The list concerns medical products: medicines, vaccines and some diagnostic devices. Research reagents, laboratory chemicals and unregistered categories generally do not enter the system because no national authority has a registration against which to call them falsified. A research buyer should therefore not expect to find a research material on the list, and should not read its absence as reassurance.

The reverse error is also possible. A listed name with no lot match is not a finding against your goods. Many alerts concern one lot, one region and one period. Treat a name match as a prompt to compare lots, and nothing more.

National regulators' own pages

National authorities publish alerts that never reach the WHO list. Kenya's Pharmacy and Poisons Board keeps a safety-alerts page ^[5]. South Africa's regulator maintains a Rapid Alert System page ^[6]. Nigeria's NAFDAC and Ghana's Food and Drugs Authority publish public alerts and press notices on their own sites. The formats and update habits differ, so check the page for the country your goods are in, and note the date you looked.

Using an alert in a goods-in check

1. Record the name, manufacturer as labelled, lot and expiry of each received item.
2. Search the WHO list and the relevant national page for the name, and note the date and the pages searched.
3. If a notice names the product, compare the lot and expiry with the notice, and the packaging with any photographs.
4. If the lot does not match, record that and carry on with the ordinary receiving process.
5. If the lot matches, quarantine the item, do not use it, and report as the regulator asks.

Keep the search record with the receiving record. It shows that a check was done, when, and where. For context on how regulators have named products in the past, see when a regulator names a product, which is a history rather than a checklist.

Dates, revisions and how old an alert is

An alert is a snapshot. It records what was known on its publication date, and the situation may have moved since. A lot named in a 2020 notice has long passed its expiry. A notice from last year may still describe packaging that is being copied. Read the date first, then decide how much weight the notice carries for goods received today.

Older alerts are still useful in one respect: they show how falsification has looked in practice, which features were copied and which were missed. That is a reason to read two or three full notices once, not only the headlines, so the vocabulary is familiar when a relevant one appears.

Alerts also differ in their reach. Some name a single country where the product was found, others name several regions. The absence of your country from a notice does not mean the goods cannot be there, because goods move between markets by routes the notice does not describe. Equally, the presence of your country does not mean your supplier handled the product. It means someone reported it nearby.

Finally, be careful about forwarding alerts. A screenshot of an alert circulated in a group chat loses its date, its number and its link. If you share one inside an institution, share the link to the WHO page and the date you read it, so a colleague can check the original.

Reporting when you hold a listed lot

If your goods match an alert, the alert itself or the national regulator's page says whom to tell. Keep the item, the packaging and the paperwork as they are, photograph them, and do not return the goods to the supplier before the regulator has said what it wants. Contact the supplier in writing as well, so the date of the notification is on record. The channels differ by country; a separate article on this site maps them.

What to do next

Bookmark the WHO list and the page for your national regulator, and add a line to the receiving form: alert lists searched, date, outcome. Then agree who owns the check. A check that belongs to no one is done when someone remembers.
