A family-run coffee production in Vietnam has been caught making coffee from used batteries, dirt and rock dust.
The facility, owned by Nguyen Thi Loan, was reported to Dak Nong police after reports from locals concerned about suspicious activity on the site, Tuoi Tre News says.
On Tuesday (local time) officials discovered rejected coffee beans and shells from other facilities mixed with other materials, including dirt and rock dust. The product had then been dyed with 35kg of black powder from the batteries.
Dak Nong police are looking to prosecute those involved, according to Tuoi Tre News.
At the time of the raid, 10 tonnes of the dirty coffee was available at the facility.
The owner admitted she has already sold more than three tonnes of product this year.
