Over the weekend, Kalcker posted on Facebook, asking Kennedy to revise the government’s warning about chlorine dioxide. It was, though, already gone: The FDA warning was last live on the agency’s site on May 15, according to an archived version of the site available on the Internet Archive. “News releases on FDA.gov are archived via content lifecycle standards,” Andrew Nixon, director of communications at the Department of Health and Human Services (HHS), tells WIRED. “Two years of content are kept on the active site, which is why that is now archived.”
Many other FDA releases from around the same time were indeed also archived over the course of the past month. Other pages that are similarly old have not been archived, and there are still several posts on the FDA site which warn against chlorine dioxide—including one outlining the prosecution of members of the Grenon family for selling the bleach solution as a Covid cure.
Nixon tells WIRED that “there is not any new FDA action and the general public health position on [chlorine dioxide] being dangerous has not changed.”
Herman did not say whether Kennedy or anyone at HHS had responded to her March email calling for the warning to be removed, and Kennedy did not respond to a WIRED request for comment about the email.
“I don’t know if it is a website error or if it was purposely removed,” she says of the warning, “but I’ll hope for the latter.”
Other proponents of the toxic solution clearly view the removal of the warning as a victory.
“I was genuinely surprised, and as someone from China, I couldn’t imagine our own government quietly removing a public warning without any announcement,” Xuewu Liu, who promotes the treatment of cancerous tumors by directly injecting them with chlorine dioxide, tells WIRED. “This quiet removal won’t immediately change everything, but it opens a door.”
Liu, who has been promoted by Kory in the past, wrote about the removal on Substack on Saturday; within hours, Kalcker, Herman, and Oates were all sharing the news on their social channels.
While the removal of the warning is a huge boon for those promoting the toxic bleach solution, it is just the first step in a push to make chlorine dioxide a mainstream treatment. In her livestream interview in March, Herman said she suggested that someone hold a “Make America Healthy Again roundtable” to discuss chlorine dioxide, while getting the FDA and the Centers for Disease Control and Prevention to conduct research into chlorine dioxide and setting standards for the toxic solution.
“We know that there is awareness and support for repurposed drugs and what are termed ‘alternative’ therapies, and we hope that the restraints and prosecutions will cease,” Herman tells WIRED of her hopes for the Trump administration. “Will they outright approve these therapies? We just don’t know. More realistically, they will hopefully encourage further evaluations towards such approvals.”
“I and other activists, scientists, have been speaking out against this lethal bleach product for more than a decade now,” says O’Leary, the Ireland-based activist. “When chlorine dioxide is ingested, it causes serious, life-threatening illness.”
Update: 6/11/2025 12:30 PM EDT: Wired has updated its description of David Oates' Telegram channel, and has clarified that Wired received a post-publication comment from Oates, in which he says that he does "not engage in sales, accept donations, or receive kickbacks" for God's Detox.
