Even small doses can kill. There is no safe threshold.
Em São Paulo, nove pessoas foram intoxicadas por metanol em bebidas que acreditavam ser legítimas — gim, uísque, vodca — consumidas em bares e encontros sociais ao longo de 25 dias. O que distingue este surto não é apenas o veneno, mas o contexto: ao contrário dos casos anteriores, que envolviam populações em situação de rua em contato deliberado com combustíveis, as vítimas desta vez eram cidadãos comuns, enganados por uma cadeia de abastecimento adulterada. A humanidade sempre conviveu com o risco invisível escondido no cotidiano; o que muda é quando esse risco se disfarça de normalidade.
- Nove pessoas intoxicadas em menos de um mês revelam que o metanol — veneno industrial sem dose segura — infiltrou-se em bebidas vendidas como legítimas em bares e espaços sociais de São Paulo.
- O surto rompe com o padrão histórico: desta vez, as vítimas não buscavam o veneno deliberadamente, foram enganadas por produtos falsificados que imitavam marcas comerciais comuns.
- Autoridades realizaram operações em 130 estabelecimentos e examinaram 48 produtos em setembro, mas as apreensões chegaram depois das intoxicações — a ameaça já havia circulado.
- O centro de toxicologia Ciatox, que atende múltiplos municípios, recebeu todos os casos em 25 dias, sinalizando uma concentração alarmante que levou a secretaria nacional de políticas sobre drogas a emitir alerta formal.
- A investigação permanece aberta e a pergunta que paira sobre autoridades e consumidores é a mesma: os nove casos são um episódio isolado ou o início de algo maior?
Nos últimos 25 dias, nove pessoas deram entrada no centro de toxicologia Ciatox, em Campinas, após consumirem bebidas alcoólicas adulteradas com metanol — gim, uísque e vodca comprados em bares e reuniões sociais em São Paulo. O padrão chamou atenção imediata das autoridades, não apenas pela gravidade, mas pela novidade do perfil das vítimas.
Durante dois anos, o Ciatox havia registrado intoxicações por metanol, mas em circunstâncias completamente distintas: pessoas em situação de rua que consumiam combustível como forma de abuso de substâncias. O surto mais grave ocorreu no primeiro semestre de 2023, quando 14 moradores de rua foram intoxicados. Agora, o veneno reaparece — mas escondido em garrafas que imitam produtos legítimos, chegando a consumidores comuns em espaços ordinários.
O metanol é um líquido industrial transparente, presente em solventes, tintas e combustíveis. Sua periculosidade está na margem quase inexistente entre uma dose prejudicial e uma fatal: o organismo humano não consegue metabolizá-lo com segurança, e pequenas quantidades podem matar.
A prefeitura de Campinas afirmou não ter registrado casos dentro dos limites municipais em 2025, mas reconheceu que o Ciatox atende uma região mais ampla. Em setembro, fiscais visitaram 130 estabelecimentos e analisaram 48 produtos em uma única operação contra o mercado ilegal de bebidas. As apreensões continuam, mas as intoxicações já aconteceram.
A secretaria nacional de políticas sobre drogas emitiu alerta formal ao receber o relatório do cluster. O que preocupa não é apenas o número de casos, mas o que eles revelam: em algum ponto da cadeia de abastecimento de álcool em São Paulo, um adulterante letal encontrou caminho até garrafas destinadas a consumidores que simplesmente queriam socializar. Se os nove casos são um limite ou um começo, a investigação ainda não respondeu.
In the past month, nine people across São Paulo have fallen ill after drinking what they thought was ordinary spirits—gin, whisky, vodka—at bars and social gatherings. The culprit was methanol, a toxic chemical that had been mixed into the alcohol. The cases arrived at Campinas's toxicology center, Ciatox, which serves multiple municipalities across the state, all within a span of 25 days. The pattern was unusual enough that authorities flagged it immediately.
What made this outbreak distinct was where it happened and who it affected. For the past two years, Ciatox had documented methanol poisonings, but those cases followed a different trajectory entirely. They involved people experiencing homelessness who deliberately consumed fuel—a grim marker of substance abuse desperation. Those poisonings clustered in specific populations and contexts. This new cluster was different. The victims were ordinary people in ordinary social spaces, drinking what appeared to be legitimate commercial alcohol. The beverages came from multiple sources and multiple types. The shift suggested something had changed in how the poison was entering the supply chain.
The region had seen a severe outbreak before. In the first half of 2023, fourteen people living on the streets were poisoned by methanol. That crisis had passed. Now, two years later, a new one was emerging—but with a different face.
Campinas city officials said they had recorded no methanol poisoning cases within city limits this year, though they acknowledged that Ciatox handles referrals from across a wider region. The city has been conducting enforcement operations against illegal alcohol markets and counterfeit spirits. Earlier in September, inspectors visited 130 establishments and examined 48 different products in a single sweep. The raids continue, but the poisonings have already occurred.
Methanol itself is a clear, flammable liquid with legitimate industrial uses—it appears in solvents, fuels, plastics, paints, and pharmaceuticals. Its danger lies in its potency. Even small doses can kill. The body cannot process it safely. Once consumed, it moves quickly through the bloodstream, and the margin between a harmful dose and a fatal one is narrow. There is no safe threshold.
The national drug policy secretariat issued the alert after receiving the cluster report from Campinas. The cases deviated sharply from the historical pattern, they noted—not in the chemical itself, but in the circumstances of exposure. People were not seeking out methanol deliberately. They were buying drinks in bars. They were socializing. They were poisoned by deception.
State health and security officials have not yet responded to requests for comment. The investigation remains open. What remains clear is that somewhere in São Paulo's alcohol supply, a dangerous adulterant has found its way into bottles destined for ordinary consumers in ordinary venues. The nine cases are the evidence. The question now is whether they are the beginning of something larger.

The Hearth Conversation Another angle on the story
Why does it matter that these poisonings happened in bars rather than among homeless populations?
Because it changes who's at risk and how the poison is moving through society. Before, methanol was something people in crisis deliberately sought out. Now it's hidden in commercial products. That means anyone buying a drink anywhere could be exposed.
How does methanol actually kill someone?
It's metabolized into formaldehyde and formic acid in the body. Those compounds attack the nervous system and organs. Even small amounts can cause blindness, organ failure, death. There's no antidote, only supportive care if you catch it early.
The article mentions Campinas says they've had no cases this year. But the alert came from Campinas's toxicology center. How does that work?
Ciatox serves multiple municipalities, not just Campinas. The nine cases came from across the region—different cities, different bars. Campinas itself may have been spared, but the poisoning is happening in the broader area they monitor.
What does a raid on 130 establishments actually accomplish if people are already sick?
It's prevention for what comes next. If they can identify which suppliers are adulterating alcohol and shut them down, they stop more poisonings. But you're right—it's reactive, not preventive. The damage is already done to these nine people.
Is there any way to know which drinks are safe?
Not visually. Methanol is colorless and odorless. You can't see it or smell it. That's what makes it so dangerous. The only real protection is enforcement—making sure illegal suppliers don't get product into legitimate channels.
