At least 133 people have died and about 225 people have been hospitalized after drinking tainted liquor in two separate incidents in India’s northeast, authorities said Sunday, The Associated Press reported. 

The victims of one of the most deadly bootleg liquor-related incidents in the country were mostly tea plantation workers in Golaghat and Jorhat districts in Assam state, said top police official Mukesh Agarwal.

Assam is India’s largest tea-producing state, with more than 1,000 plantations producing more than 50 percent of Indian tea.

The workers consumed the tainted liquor laced with methyl alcohol, a chemical that attacks the central nervous system, on Thursday and started falling unconscious. They were rushed to nearby hospitals and the death toll rose to 133 by late Saturday, police and health officials said.

Himanta Biswa Sharma, Assam’s health minister, said about 200 people who fell sick after drinking the toxic liquor are in hospitals, some in critical condition.

Manab Gohain, a doctor at the Jorhat Medical College Hospital, said 34 patients have died in the past 24 hours.
