Mysterious Chinese COVID Lab Uncovered in Reedley California


In a shocking discovery, Reedley city code enforcement officers stumbled upon a clandestine COVID lab operated by a shady Chinese company, Universal Meditech, Inc. (UMI), and its successor, Prestige Biotech, in Reedley, California.

What was supposed to be an empty building concealed a covert operation involving the production of COVID-19 and pregnancy tests, as well as the handling of various bodily fluid samples, unlabeled vials, and even genetically engineered mice carrying the COVID-19 virus.

This article delves into the details of the investigation, the involvement of state and federal agencies, and the suspicious operations of Prestige Biotech.

The Startling Discovery:

Reedley city code enforcement officers made an unexpected discovery when they noticed a garden hose attached to what was presumed to be an empty warehouse in Reedley, CA. Intrigued by this unusual sight, they decided to investigate further. To their astonishment and concern, the officers found that the building was being used to operate an unlicensed and unregulated laboratory by Universal Meditech, Inc. and its successor, Prestige Biotech.

Disturbing Contents:

During the investigation, authorities discovered that one room of the warehouse was being used for the production of COVID-19 and pregnancy tests, while other rooms contained a variety of bodily fluid samples, including blood and tissue. The most alarming find was thousands of unlabeled vials containing unidentified fluids, causing significant apprehension among investigators.

In addition to these disconcerting discoveries, the laboratory also housed hundreds of laboratory mice that had been genetically engineered to carry the COVID-19 virus. These mice were kept in distressing conditions, including overcrowded cages and inadequate access to food and water.

Involvement of State and Federal Agencies:

Reedley city officials were gravely concerned about the activities taking place on the property, and they reached out to various state and federal agencies for assistance. Fresno County Public Health, the California Department of Toxic Substance Control (DTSC), the California Department of Public Health (CDPH), and the Federal Bureau of Investigations (FBI) were all brought in to aid in the investigation and enforcement efforts.

CDPH and CDC Findings:

The California Department of Public Health (CDPH) documented the presence of embargoed medical devices, including COVID-19 and pregnancy tests, indicating that these were being developed on-site without the required licenses or permits. In addition to this, the CDC conducted an analysis of the location and found potentially infectious agents, both bacterial and viral. These included chlamydia, E. coli, streptococcus pneumonia, hepatitis B and C, herpes 1 and 5, rubella, and even samples of malaria.

Investigating Prestige Biotech:

Upon digging deeper, a friend provided information about Prestige Biotech, indicating that it was registered as a Nevada Domestic Corporation in April 2019 but was unlicensed in California. The company was publicly traded on the Korean Stock Exchange, with its headquarters based in Singapore. The President of Prestige Biotech was identified as Xiu Yao.

When Fresno City officials contacted Yao, he confirmed that Prestige Biotech had moved assets from Universal Meditech to the Fresno warehouse. Interestingly, Prestige Biotech’s operations in the Fresno warehouse were found to be illegally operating since October 2022, with the primary focus on creating COVID-19 and pregnancy test kits.

Suspicious Executive Roles:

The investigation into Prestige Biotech revealed that it was involved in antibody research and vaccine production. Furthermore, the company had a vaccine center located in Osong, Korea. However, suspiciously, no verifiable address could be found for Prestige Biotech in California, and addresses associated with authorized agents were either empty offices or unverifiable locations in China.

Allegations Against Prestige Biotech:

Prestige Biotech faced accusations of failing to comply with orders, including providing a plan for biological abatement and disposal of hazardous materials. The company was also accused of failing to obtain the necessary licenses or permits for experimentation and other laboratory activities.


The discovery of the illegal COVID lab operated by Prestige Biotech in Reedley, CA, has raised serious concerns about the potential infiltration of Chinese government-sponsored operations into domestic American society. With unlicensed and unregulated practices, the laboratory posed significant risks to public health and safety. The involvement of state and federal agencies highlights the importance of vigilant monitoring and enforcement to safeguard the well-being of communities and ensure compliance with relevant regulations.

In February 2023, the FDA reported a recall of Universal Meditech’s COVID-19 test kits: I thought Prestige Biotech took over for Universal Meditech, which is now defunct and going through the bankruptcy process. And why is the FDA now doing a recall of a defunct company, and not during COVID?
