NEW TRIPOLI, Pa. - Inside Eight Oaks Farm Distillery's barn, it's clear the business is fueled by grain.

"How good does it feel to be back selling again?" WFMZ's Bo Koltnow asked owner Chad Butters, in front of a product shelf.

"It feels great to be back at this, it's what we are all about," he said.

But as COVID-19 hit in March, the New Tripoli company's business model went from ingesting alcohol, to applying it. Butters says they've produced 30,000 gallons of hand sanitizer.

The company "had to register our product and spell out exactly how it's made," he said.

Alcohol, hydrogen peroxide, water and a denaturant are the strict FDA-safe ingredients Butters said he had to use.

However, the FDA has released a growing list of more than a dozen brands that are going against that grain, including five added this week from Mexico.

The highly toxic substance methonal is being found in some hand sanitizers, even though it doesn't show on the listed ingredients.

It's "used in brake fluid and other commercial-grade automotive products," said LVHN medical toxicologist Dr. Kenneth Katz.

Although it can be absorbed into the skin, the real danger is if someone drank it, which Katz says alcoholics are prone to do.

"Very life-threatening and can cause permanent blindness," Katz said.

The FDA is warning people to not use the brands that may be found in stores and online. The agency has put an import ban on those products.

A full list is posted on their website.

As for Butters, he's now back to his roots, but with the same careful eye on his ingredients.

"This week we are harvesting wheat and turning that into vodka, gin, and dry whiskey," he said.
