A former employee of Neuralink has come forward with alarming accusations, claiming she was attacked by monkeys carrying a dangerous virus during her tenure as an animal care specialist at the company.
Lindsay Short, who joined the Elon Musk-founded firm in 2021, has filed a lawsuit in California. She alleges that throughout her employment, she was repeatedly scratched by rhesus macaque monkeys that were infected with Herpes B. The virus poses a significant threat to humans, as it can lead to severe brain inflammation and spinal cord damage, potentially being fatal if not swiftly treated. This underscores the necessity for stringent safety measures for those working with such animals.
Dr. Lisa Jones-Engel, a veteran in primate research with six decades of experience at the Washington National Primate Research Center (WaNPRC), shed light on the prevalence of Herpes B in macaques during an interview with the Daily Mail. She explained that the virus is more common among these primates than widely recognized.
“Herpes B is enzootic in macaques, meaning that under natural conditions, animals are exposed and infected by the time they are about three years old,” Dr. Jones-Engel elaborated. She further noted that the virus often remains latent and clinically silent, posing significant detection challenges. This can result in colonies appearing virus-free on documents when the reality is quite different.
‘Herpes B is enzootic in macaques, meaning that under natural conditions, animals are exposed and infected by the time they are about three years old,’ the expert said.
‘The infection is often latent, intermittent, and clinically silent, which makes it difficult to detect and easy to miss, so colonies may appear virus-free on paper when they are not.’
The lawsuit claims that, in 2022, a monkey reached through the bars of its cage and scratched through Short’s glove to her hand, ‘exposing her to Herpes B in the process.’
A year later, according to the suit, Short was reportedly clawed in the face by another virus-infected primate. Short ‘was brutally scratched by monkeys on no less than three separate occasions within a six-month period,’ the lawsuit claims.

The Daily Mail has reached out to Short, her lawyers at Valliant Law and Neuralink, and has yet to receive responses.
Jones-Engel said that even animals that test negative can still pose serious risks to handlers.
‘Monkeys can test negative and still harbor the virus, or only shed it intermittently,’ she explained.
‘That’s why federal guidance emphasizes treating all macaques as potential carriers, regardless of their test status.’
Short alleges in the lawsuit that after reporting safety concerns, requesting medical care, and later disclosing her pregnancy, she was demoted and ultimately terminated, actions she claims were retaliatory.
The lawsuit states: ‘In each and every instance, Plaintiff was exposed to a potentially life-threatening virus, but at no point did Neuralink alter its policies or provide Plaintiff with Workers’ Compensation.’
Neuralink has faced growing scrutiny over its animal testing practices, particularly regarding rhesus macaque monkeys used in brain-implant experiments.
In 2022, federal regulators opened an investigation into potential animal welfare violations after advocacy groups and employees raised concerns that some procedures may have caused infections, complications, and deaths among test animals.

Separately, in 2023, the Physicians Committee for Responsible Medicine (PCRM), a nonprofit medical advocacy group, called for a federal investigation into whether the company violated hazardous material transport laws.
The federal probe concluded in 2023 when regulators said they found no systemic violations of federal animal welfare rules.
However, subsequent inspections by other agencies flagged quality-control issues, keeping scrutiny on the company’s research practices.
Federal health guidelines from the National Institutes of Health and the Centers for Disease Control and Prevention require enhanced protective equipment to prevent direct skin exposure when working with research animals.
However, according to her lawsuit, Short alleges she was not provided with proper safety gear and was instead issued reusable scrub jackets that left parts of her wrist exposed.
Federal biosafety standards require strict protective equipment when working with macaques, said Jones-Engel.
‘At minimum, federal guidance calls for gloves, protective clothing such as lab coats, and face protection like a face shield when working with macaques or their tissues,’ she explained.
‘In practice, exposures like bites or scratches should trigger immediate use of a Herpes B scrub kit and urgent medical evaluation.’
Short’s complaint states the first major incident occurred in September 2022, when a rhesus macaque allegedly reached through the bars of its cage and scratched her hand.
The filing claims the animal’s claws tore through her glove and broke the skin, raising fears of possible infection. According to the lawsuit, she immediately reported the injury and sought medical treatment.
Short alleges the response from management was not supportive. Instead, she claims supervisors reacted negatively, a reaction she believes may have been linked to federal reporting requirements triggered by workplace injuries involving research animals.
However, Jones-Engel noted that reporting requirements around Herpes B exposures are often misunderstood.
‘I have never seen regulations that require facilities to report worker Herpes B exposures to the USDA,’ she said.
‘If medical treatment beyond first aid is required, the injury may be recorded on an OSHA log, but not every exposure must be formally reported.’

The Daily Mail has contacted OSHA and has yet to receive a response.
According to the complaint, tensions escalated in the weeks that followed as Short continued raising concerns about safety practices.
The filing alleges the situation intensified in March 2023, when Short was assigned to perform a procedure she claims she had not been trained to carry out. During the task, the lawsuit alleges, a monkey scratched her across the face, prompting another request for medical care.
According to the complaint, supervisors reacted angrily and warned there would be ‘severe repercussions’ if similar incidents occurred again.
Short alleges that after continuing to raise concerns about safety, training and reporting standards, her working conditions began to change.
According to the lawsuit, she was demoted in May 2023 from a full-time salaried role to a reduced hourly position with fewer benefits.
Short further alleges workplace tensions escalated in June 2023 after she informed the company’s human resources department that she was pregnant and requested workplace accommodations.
According to the complaint, less than 24 hours later, she was called into a meeting and presented with a separation agreement and notice of termination citing performance issues.
The lawsuit states the close timing between her pregnancy disclosure and termination raised concerns of retaliation.
Short claims she was terminated despite previously receiving a promotion earlier that year.
The complaint outlines multiple legal claims against the company, including retaliation, pregnancy discrimination, whistleblower retaliation, wrongful termination, and emotional distress.
According to the lawsuit, Short suffered financial losses, emotional distress, anxiety, and other hardships following her termination.
She is seeking damages for lost wages, emotional distress and other financial losses.
Jones-Engel emphasized that working with macaques requires constant vigilance and rapid medical response following any injury.
‘Personnel should be properly trained, appropriate protective equipment must be used, and any bite or scratch should trigger immediate first aid,’ they said.
‘CDC guidance recommends scrubbing the wound with soap or iodine for 15 minutes, flushing it for another 15 to 20 minutes, and seeking urgent medical care.’
Neuralink has not admitted wrongdoing, and the claims outlined in the lawsuit remain allegations that have not been proven in court.
