More than a dozen kinds of hand sanitizer should be avoided because they may contain methanol, a toxic substance when absorbed through skin or ingested.

The Food and Drug Administration says many of the products have been voluntarily recalled with other products being recommended for recalls because they may contain the potentially fatal ingredient. All of the products in the FDA's latest methanol update were produced in Mexico.

The FDA says it has "seen a sharp increase in hand sanitizer products that are labeled to contain ethanol (also known as ethyl alcohol) but that have tested positive for methanol contamination."

The recalls come after the FDA warned consumers in June not to use nine kinds of hand sanitizers because they may contain the potentially fatal ingredient.

"Methanol is not an acceptable active ingredient for hand sanitizers and must not be used due to its toxic effects," the FDA said, noting its investigation of methanol in certain hand sanitizers is ongoing.

Methanol is used industrially as a solvent, pesticide and alternative fuel source, according to the Centers for Disease Control and Prevention. Exposure to it can cause nausea, vomiting, headache, blurred vision, permanent blindness, seizures, coma, permanent damage to the nervous system and death.

Children who accidentally ingest hand sanitizer and young people who drink hand sanitizer as an alcohol substitute are at an increased risk for methanol poisoning, the FDA said.

The CDC says hand-washing with soap and water for at least 20 seconds is the best way to clean your hands, but when that's not an option, the agency recommends using an alcohol-based hand sanitizer with at least 60% alcohol.

Hand sanitizer has been a popular product to combat the coronavirus since February and many new types of hand sanitizer have entered the market after shortages of brands including Purell.
