Brazil’s Health Ministry is advising people to refrain from consuming cocktails after methanol-contaminated liquor resulted in at least one fatality, caused blindness in others, and sparked widespread panic.

Across the country, from the chic bars of São Paulo to the beaches of Rio de Janeiro, fear is rampant following a series of potential methanol poisonings, leading to fatalities, blindness, and comas among drinkers.

Authorities have verified one fatality due to methanol poisoning. The Health Ministry reports 127 suspected cases nationwide, with 11 confirmed and 116 under investigation in at least five states, including the capital, Brasília.

Reportedly, victims include patrons of high-end bars and restaurants, with some losing their vision or falling into comas after consuming popular Brazilian caipirinhas, vodka tonics, and other clear beverages.

Federal police are investigating a potential link to organized crime groups accused of distributing counterfeit liquor.

Methanol is an industrial chemical that can cause nerve and liver damage and is sometimes found in fake or poorly distilled alcohol.

Restaurant owners are suspending liquor sales to reassure nervous customers. 

“No one was purchasing drinks last night… even I’m hesitant to drink,” stated Nikolaos Loukopoulos, who operates a Greek restaurant in São Paulo. “A beer suffices in this heat; why take the risk?”

While tourist favorite Rio de Janeiro has yet to see confirmed cases, eateries and beachside kiosks are posting warnings on social media to reassure tourists.

Thais Flores, a 28-year-old dental surgeon visiting Rio from São Paulo, said she reluctantly ordered a Corona at a beach kiosk. 

“I don’t really like beer, but because of the latest news, it’s been my drink of choice.”

Her friend, Raquel Marques, 29, said she risked drinking a vodka caipirinha anyway. 

“I’m scared, but we took a chance,” she said. “The guy said he bought it at the market.”

The scare comes as Brazil prepares for its peak tourism season, raising fears of an economic hit to its beaches and nightlife industry.
