Methanol is highly toxic for humans, and increased amounts can show up in fraudulent or illegal alcoholic beverages. Dozens of methanol poisoning cases still happen every year around the world, some of them being deadly, according to the World Health Organization (WHO). The FBI is assisting the Costa Rican Police in the investigation of 20 recent deaths that are possibly methanol-related. Costa Rican authorities have searched a production facility, seized liquor and issued a nationwide alert.
