Tanzania
Although Tanzania government banned illicit alcohol, the country still produces 51% of such drinks. One of the popular yet illicit drinks is gongo, made from fermented then distilled scraps of ugali and maize: some brewers add mixing ethanol, formaldehyde and other poisons to speed up fermentation, leading to blindness in consumers.
In 2017, the government stepped up the fight against illicit alcohol by “launching an electronic stamp system to ensure that ethanol is registered and that suppliers sell only to registered alcoholic drinks producers.”
