On June 7, 2025, the Massachusetts Department of Public Health warned the public about a growing cluster of botulism cases linked to cosmetic botulinum toxin (commonly referred to as “Botox”) injections administered at Rodrigo Beauty, located in Milton, Massachusetts. At that time, ten cases of suspected botulism were under investigation, all associated with Rodrigo Beauty.
In December 2025, the U.S. Attorney's Office in Massachusetts announced that the spa's owner, Rodrigo de Medeiros Siqueira, had agreed to plead guilty to misbranding of a drug with the intent to defraud or mislead. According to the office's press release, Medeiros Siqueira falsely told clients that he licensed to perform injections, and lied about the contents and source of the botulinum toxin products he was using.
Authorities are asking anyone who received unapproved cosmetic injections from Medeiros Siqueira or Rodrigo Beauty to fill out a victim witness questionnaire on the FDA's website.
April 2024: U.S. officials warn about botulism-like illness linked to counterfeit Botox
The FDA released images of the fake Botox causing illness and hospitalizations across the country.
According to officials in Illinois and Tennessee, six people developed a botulism-like illness and four of them were hospitalized after receiving cosmetic injections in what the CDC has characterized as “non-medical settings.” Investigators have examined cases in 11 states and excluded reports in Washington and Nebraska from the outbreak. As of May 8, 2024, a total of 15 people from 9 states have reported harmful reactions after receiving injections.
Patients presented with classic signs of botulism, which include blurry or double vision, droopy eyelids, difficulty breathing, fatigue, slurred speech and hoarse voice. The disease can progress to total paralysis, and can be fatal.
