A suspected methanol-contaminated herbal alcoholic drink has claimed the lives of 49 people in Ondo State, while 182 others have been affected in one of Nigeria’s deadliest poisoning outbreaks in recent years.

The outbreak was recorded in Odigbo and Irele Local Government Areas, where dozens of residents developed severe symptoms shortly after consuming the locally brewed herbal drink. Health authorities said many victims suffered sudden blindness, kidney failure and brain damage before dying.

Ondo State Commissioner for Health, Banji Ajaka, confirmed that 182 people were affected by the poisoning, with many hospitalised for emergency treatment. He explained that the suspected methanol acts rapidly once consumed, causing irreversible damage to vital organs depending on the quantity ingested.

According to survivors, the drink is believed to be a contaminated version of “Monkey Tail,” a popular locally produced herbal alcoholic beverage widely consumed in parts of southern Nigeria. Residents said they suspect methanol was mixed into the concoction before it was sold to consumers.

The Ondo State Police Command has arrested 15 suspects, including a person believed to have been involved in producing the suspected methanol-laced substance. Investigators say the arrests form part of ongoing efforts to determine the source of the contaminated drink and prevent further distribution.

Public health experts say the tragedy also reflects the growing reliance on cheaper, unregulated alternatives as many Nigerians struggle with the rising cost of healthcare and orthodox medicines. Locally brewed herbal mixtures remain popular in many rural communities because they are more affordable, despite limited regulation and significant safety risks.

The National Agency for Food and Drug Administration and Control (NAFDAC) has continued enforcing its nationwide ban on alcohol sold in sachets and small plastic containers, citing concerns over unsafe production practices and easy access to such products.

Health authorities have urged residents to avoid consuming unverified herbal alcoholic drinks and to seek immediate medical attention if they experience symptoms such as blurred vision, vomiting, difficulty breathing or sudden loss of consciousness after consumption.
