In many areas of Sulawesi Island (Indonesia), black fruit bats (aka black flying foxes) are the main source of meat for local people.
The bats are hunted and caught in the jungle by locals using just fishing lines and hooks, or nets.
They are then sold as bushmeat in local meat shops. Apparently there is still plenty of fruit bats in the jungle, so they are pretty inexpensive on the meat markets.
The bat wings are always separated from the body of the bat.
After cutting off their wings, they impale the bat bodies with a stick through their mouth, and singe them with a blowtorch, to remove their fur.
They also singe the wings, I think to kill parasites that could be on the bat wing skin.
Bats carry all kinds of viruses including coronaviruses, but fruit bats do not carry the COVID-19 virus. However all bats can carry the lyssavirus (closely related to rabies) which can cause serious illness in humans. But the chances of getting infected by this bat virus are very small.
