“The buck stops here.”
Harry S. Truman, sign on his Oval Office desk
Neogen sold a vial with one word on it that mattered, and nobody at Neogen owned whether that word was true.
THE SIGNAL
On January 28, 2026, Neogen recalled every unexpired lot of HYCOAT, a hyaluronate wound solution labeled sterile, for microbial contamination.
Eight months later the FDA showed how bad it was.
A September 23 warning letter to CEO Mike Nassif said FDA testing of lot 5A001 found five live fungal species. More than 95 horses were involved and at least 20 were euthanized. That is the most horse deaths the FDA has ever tied to a quality defect in a veterinary medical product.
The headlines are about the horses.
Underneath them is a simpler fact.
Neogen didn’t make HYCOAT. A contract manufacturer, Sciarra Aeromed, made it in a cleanroom the FDA found built inside a warehouse.
Neogen put its name on the box.
Most coverage is fighting over off-label joint injections. That’s noise.
The signal is who verified the word “sterile.”
THE FAILURE POINT
The break didn’t happen at the January recall. It happened every day Neogen shipped “sterile” on the strength of a supplier’s word.
Inspectors found no sporicidal cleaning, no sampling for viable microbes in the air or on personnel, no smoke studies of the critical airflow, and gowning that left skin exposed.
The FDA said Neogen “could have easily discovered and acted upon” what it found.
Nobody went to look.
SIGNAL WITHIN THE SIGNAL
Signal Compression.
Inside the warehouse, the truth was specific: no viable sampling, a room in disrepair.
By the time it reached Neogen, it was a line on a supplier certificate.
By the time it reached a vet in a barn aisle, it was one word printed on glass.
Each handoff kept the claim and dropped the evidence. “Sterile” was the most compressed signal in the chain and the most trusted one.
Worth checking where your own team sits on that same gap before assuming it's someone else's problem.

BEHAVIOR UNDER PRESSURE
When the adverse event reports came in, Neogen recalled.
That part was right.
Then it reached for the label.
The recall notice stressed that the injuries followed joint injections, which it called inconsistent with the product’s intended use.
According to the FDA letter, Neogen objected during recall talks to the agency counting off-label use at all. The FDA pointed out that Neogen had once promoted HYCOAT for exactly that use and had been warned about it in 2000.
Under pressure, leadership defended the edge of the label instead of the contents of the vial. It probably felt like precision. From the barn, it looked like distance.
SYSTEM DRIVER - MOS
The system manufactures trust out of paperwork.
A certificate of sterility stands in for proof of sterility, and nobody inside the company is assigned to tell the two apart.
The structural fix is one rule: every outsourced product carrying a safety claim on your label gets a named internal owner.
That owner has personally seen the environmental monitoring data and the media fill results, and has walked the site within the last twelve months.
Their name goes in the supplier file. No name, no release.
LEADER DRIVER - INTERNAL OPERATING SYSTEM (IOS) - REGULATE
The read suggests the people arguing the off-label point were protecting exposure. That’s a defensible reflex for counsel and a costly one for a leader.
The missing override threshold was simple. Once animals are dying, the question changes from “are we liable” to “was our word true.”
A leader regulated enough to ask the second question first stops litigating the label and gets on a plane to the warehouse.
IF YOU DO ONE THING TODAY
Pull the list of products a contract manufacturer builds under your name.
Find the one with the strongest claim on its label:
sterile
food grade
certified
rated to a load
Ask one question in writing: who here has seen the evidence behind that claim, and when?
If the answer is a PDF in a shared drive, put one person’s name next to that product today and get a site visit on the calendar before you leave.
FINAL SIGNAL
You can outsource the cleanroom, but the word on the label is always yours.
