In one of the most consequential lab fraud cases in the history of regulated cannabis in the United States, New York’s Office of Cannabis Management announced a recall of cannabis products from 54 lots after a records audit revealed that Keystone State Testing New York had issued unreliable test results for Aspergillus contamination.
What the Investigation Found
An OCM inspection and records audit conducted between December 2025 and January 2026 found that Keystone State Testing had falsely reported products as passing Aspergillus testing when the products did not actually meet New York’s safety standards. An additional product lot was found to have an incorrectly reported result for cadmium, a heavy metal.
The OCM determined that the unreliable results were not random errors. The pattern of falsification suggested a systemic problem with how Keystone was conducting and reporting Aspergillus testing for adult-use cannabis products in New York’s licensed market.
The Scope of the Recall
54 product lots is an enormous number for a single lab fraud case. These products had been distributed through New York’s licensed adult-use retail network and had reached consumers on the basis of test results that regulators now deemed unreliable. The OCM issued public recall notices and worked with licensed retailers to pull affected products from shelves.
For the brands whose products were included in the recall, the damage extended far beyond the immediate economic hit of destroyed inventory. Consumer trust, retailer relationships, and brand reputation all took damage as a result of a third-party testing failure entirely outside the brands’ control.
The Systemic Lesson
The Keystone case illustrates a painful reality for cannabis cultivators: your product’s compliance status is only as good as the integrity of the lab that tests it. A cultivator who grew clean, properly dried and cured flower can still end up in a recall if their testing lab provides fraudulent results. The only way to break this dependency is to build quality assurance systems that establish the cleanliness of product independently of the third-party test — through proactive decontamination, internal monitoring, and rigorous documentation of the post-harvest process.
