Unannounced FDA Inspections: Why Surprise Visits Are Critical for Drug and Food Safety

December 29, 2025 0 Comments Jean Surkouf Ariza Varela

The U.S. Food and Drug Administration doesn’t call ahead. No warning. No schedule. One day, a team of inspectors walks into a factory making your medicine, baby formula, or medical device - and they’re there to see exactly what’s happening right now, not what was cleaned up for the visit. This isn’t a drill. It’s the new normal.

Why Surprise Visits Exist

Imagine you’re running a kitchen. Every week, the health inspector shows up without notice. You can’t scrub the counters the night before. You can’t hide expired ingredients. You can’t ask your staff to fake their training records. That’s how the FDA sees drug and food manufacturing. The goal isn’t to catch people being bad - it’s to make sure they’re never tempted to be.

For decades, the FDA did unannounced inspections on U.S. facilities. But foreign factories? They got weeks of notice. Translation services were arranged. Managers were flown in. Records were polished. The FDA found serious problems more than twice as often in those pre-announced foreign inspections compared to domestic ones. That wasn’t oversight - it was theater.

On May 6, 2025, the FDA ended that double standard. Now, every facility - whether in Ohio or Osaka - gets the same treatment: no advance warning. The agency says it’s about fairness. But the real reason is simpler: if you know you’re being watched, you behave. If you think you might be watched at any moment, you stay honest.

How an Unannounced Inspection Actually Works

It starts with a knock. No phone call. No email. FDA inspectors show up in person, usually in pairs. They flash their badges, hand over Form FDA 482 - the official Notice of Inspection - and ask to speak with the most responsible person on-site. That person doesn’t have to be the CEO. It could be the night shift supervisor. The key is: whoever’s there, they’re the one accountable.

Then comes the walk-through. Inspectors don’t just look at clean rooms. They check:

  • Raw material logs - are they dated, signed, and traceable?
  • Equipment maintenance records - is that sterilizer calibrated, or just cleaned up before the last visit?
  • Employee training files - are people actually trained, or just listed on a spreadsheet?
  • Batch records - does the data match what happened on the floor?

They might ask to see a live production run. Or walk into a sterile manufacturing area without warning. No prep time. No rehearsed answers. If the facility’s quality management system (QMS) is a patchwork of Excel sheets and sticky notes, it’s going to fall apart fast.

Inspections can last hours or days, depending on complexity. The FDA doesn’t rush. They’re not there to scare you. They’re there to find the truth.

Split scene: staged clean factory vs. real chaotic production floor under an inspector's flashlight, highlighting inspection truth vs. pretense.

What Happens When They Find Problems

Not every inspection ends with a violation. In fact, about 15% of domestic inspections result in a “No Action Indicated” report. That’s not a pass - it’s intelligence. The FDA uses those clean inspections to build risk profiles. A facility that passes three unannounced visits in a row? It gets lower priority for the next round.

But if they find issues? You get Form FDA 483 - a list of observations. These aren’t fines. They’re warnings. Examples: “Sterilization records missing for 12 batches,” or “Personnel not trained on change control procedures.”

Worse? If they find fraud - falsified data, hidden complaints, destroyed records - that’s a criminal offense. The FDA can seize products, block imports, or shut down operations. And they don’t need a court order to do it. They have the legal right to refuse entry if a company delays, denies, or limits access.

Foreign manufacturers aren’t protected by geography. If you ship medicine to the U.S., you’re under FDA jurisdiction. No exceptions.

Why This Change Hit Foreign Manufacturers Hard

Before May 2025, the FDA conducted about 3,000 inspections overseas each year. Most were in India, China, and other manufacturing hubs. These facilities had grown used to the old system: get a heads-up, tidy up, hire translators, and wait for the inspectors to leave.

Now? That’s over.

The FDA’s own data shows that when foreign facilities were given advance notice, over 90% of inspections turned up serious quality issues. Domestic facilities? Around 45%. That gap wasn’t because American factories are better. It’s because foreign ones had time to fix appearances - not real problems.

Now, inspectors are arriving cold. No translators pre-arranged. No management on standby. That’s exposing gaps in training, language barriers, and weak documentation systems that were hidden behind planning.

Companies that relied on “just-in-time compliance” are scrambling. Some are hiring full-time FDA response teams. Others are investing in digital QMS software that tracks every step - automatically - so there’s no room to fake it.

What Manufacturers Need to Do Now

You can’t prepare for a surprise. But you can prepare for anything.

Here’s what actually works:

  1. Train everyone - not just managers. The night shift worker who handles the autoclave needs to know what to say, what documents to pull, and who to call. Practice with mock inspections every quarter.
  2. Digitize your records - paper logs are easy to lose. Spreadsheets are easy to edit. A real QMS system locks data, tracks changes, and stores audit trails. If you’re still using Word docs for batch records, you’re already behind.
  3. Keep your facility clean - always - not just before inspections. If the floors are sticky, the air filters are clogged, or the packaging area is cluttered, inspectors notice. It’s not about perfection. It’s about consistency.
  4. Know your supply chain - if your raw materials come from a supplier that failed an FDA inspection, you’re at risk too. The FDA doesn’t just look at you. They look at who you rely on.
  5. Have a response plan - who answers the door? Who calls legal? Who accesses the electronic records? Write it down. Test it. Update it.

There’s no magic checklist. But there is one rule: if you’re not ready for a surprise, you’re not ready to sell in the U.S.

The Bigger Picture

This isn’t just about FDA rules. It’s about trust.

Over 80% of the active ingredients in U.S. medicines come from overseas. Nearly 40% of finished drugs are made abroad. If those facilities cut corners, people die. The FDA knows this. That’s why they’re not asking for cooperation - they’re demanding accountability.

The May 2025 policy change didn’t come out of nowhere. It followed a presidential executive order pushing for stronger oversight of global supply chains. It came after years of scandals involving contaminated baby formula, falsified test results, and counterfeit cancer drugs.

The message is clear: if you want to sell in America, you play by American rules. No exceptions. No loopholes. No advance notice.

The FDA isn’t trying to punish companies. They’re trying to protect you - the patient, the parent, the person taking that pill every morning. And they’re willing to show up unannounced to make sure you’re safe.

Are all FDA inspections unannounced?

No. Most are, but there are exceptions. For example, inspections for Class II or Class III medical devices are usually scheduled every two years. Also, if the FDA needs specific records or personnel that aren’t always available, they may give notice. But for quality system audits, follow-up visits, or “for cause” inspections - those are always unannounced.

Can a foreign company refuse an FDA inspection?

Technically, yes - but refusing means you’re blocking your products from entering the U.S. The FDA can legally deny entry to any drug or food product from a facility that delays, denies, or limits an inspection. That’s not a threat. It’s the law.

Do FDA inspectors work with foreign regulators during unannounced visits?

It’s unclear. Before May 2025, the FDA often coordinated with local health authorities, shared inspection plans, and invited them to observe. Since the policy shift, the FDA hasn’t confirmed whether that practice continues. Many industry lawyers say this is one of the biggest unanswered questions - and it could create legal risks for foreign manufacturers if local authorities aren’t informed.

What happens if I don’t have a translator during an unannounced inspection?

You’re expected to have someone on-site who can communicate in English - even if they’re not a professional translator. Many companies now train key staff in basic FDA inspection vocabulary. If no one can communicate, the inspection may be delayed or halted, but that doesn’t stop the FDA from taking action later. It just makes things harder for you.

How often do unannounced inspections happen now?

The FDA hasn’t published exact numbers, but they’ve said they plan to increase the frequency of unannounced inspections at foreign facilities. High-risk manufacturers - like those with past violations or complex processes - can expect visits every 12 to 18 months. Lower-risk ones might go two to three years. But since they’re unannounced, you can’t assume you’re safe just because you haven’t been visited recently.
