CDC warns of the dangers of drinking hand sanitiser after fatal poisonings

Federal health authorities issued a formal warning Wednesday about the dangers of drinking hand sanitiser and alerted poison control centres across the nation to be on the lookout for cases of methanol toxicity after four people died and nearly a dozen became ill.

From May 1 to June 30, 15 people in Arizona and New Mexico were treated for poisoning after they swallowed alcohol-based hand sanitiser, the Centers for Disease Control and Prevention said.

Three of the patients sustained visual impairments, according to the CDC, which said that drinking hand sanitiser can cause methanol poisoning. Methanol is a type of alcohol commonly found in fuel products, antifreeze, industrial solvents and in some preparations of hand sanitiser that federal health officials said is harmful and should not be used.

Hand sanitiser has become a ubiquitous and often scarce substitute for hand washing during the coronavirus pandemic. The CDC has recommended the use of ethyl alcohol- or isopropyl alcohol-based hand sanitiser if soap and water are not readily available.

“Alcohol-based hand sanitiser products should never be ingested,” the CDC said in the advisory Wednesday.

It was not immediately clear if any of the people who were poisoned drank the hand sanitiser for its disinfectant properties. The CDC said some adults had consumed it for its alcohol content.

Health officials warned that drinking hand sanitiser made with either methanol or ethanol could cause a headache, blurred vision, nausea, vomiting, abdominal pain, loss of coordination and decreased level of consciousness. Methanol poisoning can additionally result in metabolic acidosis, seizures, blindness and death, they said.

“Swallowing alcohol-based hand sanitiser products containing methanol can cause life-threatening methanol poisoning,” the CDC said. “Young children might unintentionally swallow these products, whereas adolescents or adults with history of alcohol use disorder might intentionally swallow these products as an alcohol (ethanol) substitute.”

Last week, the Food and Drug Administration, which regulates hand sanitisers, announced that it had placed methanol-based hand sanitisers manufactured in Mexico on an import alert because of their toxicity. It also said it was working with retailers to recall that type of hand sanitiser and remove those products from marketplaces.

“Consumers must also be vigilant about which hand sanitisers they use, and for their health and safety we urge consumers to immediately stop using all hand sanitisers on the FDA’s list of dangerous hand sanitiser products,” Dr Stephen M Hahn, the agency’s commissioner, said in a statement on July 27.

In June, the New Mexico Department of Health announced that three people had died, three were in critical condition and one was permanently blind after ingesting hand sanitiser that contained methanol.

A spokesman from the health department said at the time that the cases were related to alcoholism, noting that hand sanitiser was sometimes consumed for its high alcohol content.

In 2016, a former Wells Fargo employee drew widespread attention after she told The New York Times that she had been under so much stress at her job during a banking scandal that she drank hand sanitiser and became addicted to it.

The rise in poisoning cases of people who drank hand sanitiser drew the attention of public health researchers, who wrote about it in a 2012 report.

Dr Anthony F Suffredini, a senior investigator at the National Institutes of Health and an author of the report, described the case of a 17-year-old hospital patient who became acutely ill after putting hand sanitiser into his feeding tube while being treated for other medical problems. The boy required mechanical ventilation to assist with his breathing and dialysis to rid his blood of the alcohol.

“This young man, who was from the South, mentioned that among his circle of friends, who were all underage, if they couldn’t find alcohol any other way, this was one of the ways they tried to get high,” Suffredini said at the time.
