The ministry issued a July 4 alert about the methanol issue only for drinks identified as Guaro Montano, but expanded its warnings after collecting samples of alcohol under several other names.
The deaths have been growing more frequent, rising from one or two a week in June to 14 over two weeks in July.” The victims include 15 men and five women all over 30 years old, with an additional death still under investigation, the health ministry said Monday in a news release.
Costa Rican President Carlos Alvarado Quesada tweeted last Friday of his regret for the lives lost, saying that he has told authorities to “collect all possible data to establish responsibility.”
Donald Corella, head of emergency services at Calderon Guardia Hospital in the city of San Jose — where seven of the deaths reportedly occurred — told the Argentine newspaper La Nacion that some of the bad alcohol tested consisted of 30 to 50 percent methanol.
The four people who survived the poisoning at the hospital had “very serious aftereffects,” such as total blindness and Parkinson’s disease-like tremors caused by brain lesions, he said.
The Ministry of Health has advised the public not to consume or sell the six brands of alcohol unless they are sure a product has not been tampered with. Anyone with symptoms of methanol poisoning — which include abdominal pain, headaches, dizziness, confusion and inability to coordinate body movements — is asked to contact the Ministry of Health.
Authorities have also closed stores that continued selling the tainted brands despite the health warning, which remains in effect nationwide, Health Minister Daniel Salas Peraza said in a statement Wednesday to The Post.
Officials searched a distributor called Pinares de Heredia in the town of San Isidro de Coronado to investigate methanol-tainted Aguardiente Estrella Red-brand alcohol, the health ministry said Wednesday. Authorities seized alcohol there after discovering that drinks did not have a sanitary registration or that their registration had expired. Samples of the drinks are being analyzed, and the ministry continues to confiscate containers.
Methanol is widely available and present in household items such as varnishes and antifreeze, according to the World Health Organization. Methanol also occurs naturally in fruit juice and shows up in low levels in fermented drinks such as alcohol.
Badly managed distillation can lead to toxic amounts of the chemical in alcohol, the WHO says, but particularly dangerous is the practice of adding methanol to “informally produced” drinks or tampering with existing ones. Sellers may add methanol to increase their alcohol’s potency.
The WHO warns that drinks with too much methanol can make their way into both legal and illegal drinking areas, especially in some tourist spots. Fake labeling can trick customers into thinking they are buying established brands at what seems like bargain prices.
Methanol poisoning victims often delay getting medical help, the WHO adds. Health issues can take a while to show up, and a person who consumes it might think initial symptoms are just signs of drunkenness. Those poisoned may vomit, feel vertigo or hyperventilate, and can even experience blindness. Toxic amounts of methanol can lead to coma, convulsions and death, and survivors could have permanent damage to their vision.
Different people can find different concentrations of methanol deadly, Costa Rica’s Ministry of Health said. A person’s weight and drinking habits may affect how a tainted drink will affect them.
In addition to the seven victims who died in San Jose, the ministry has reported four deaths in Cartago, three in Limon, two in Guanacaste and one in Heredia. The ministry did not provide the location of the other two deaths, saying investigations are pending.
“It is important to emphasize that these data are preliminary since the investigations continue,” the ministry wrote in Spanish.
The U.S. Embassy in Costa Rica said in an alert issued Tuesday that it is not aware of any U.S. citizens sickened by tainted alcohol, and Costa Rica’s Ministry of Health said no tourists have been affected. Eighteen of the dead were Costa Ricans, while another was Nicaraguan, and most had chronic alcoholism, the ministry said.
Methanol poisoning outbreaks from toxic alcohol have occurred all around the world, in some cases making hundreds ill and leading to the deaths of nearly a third of those sickened, the WHO has said.
At least 154 people were reported dead in February in India after drinking unregulated, “country-made liquor.” More than 200 others were hospitalized.
The deaths of three U.S. citizens in the Dominican Republic this year led hundreds to report illnesses while traveling in the country to iwaspoisoned.com, but The Washington Post has not verified the reports. Both U.S. and Dominican Republic officials have said the number of deaths is not unusual, though, and Dominican authorities have said they are not aware of any strange spike in tourist illness.
