In early October, Brazil faced a nationwide health emergency as adulterated alcohol, primarily white spirits like vodka and cachaça, was laced with toxic methanol—an industrial chemical used to falsely boost alcohol content.

Authorities suspect organized crime diluted liquor to evade taxes or increase profits, triggering widespread contamination that sickened hundreds of people—with symptoms like blinding headaches, vomiting, and organ failure—and killed at least 10 people.

Are there any public health lessons to learn from this tragic episode?
