Didn't the last Ebola epidemic occur partially because people were eating bush meat which was a bat with Ebola? I believe this is correct.
Now, this does not mean that all bats have issues or diseases. Just like people here think ALL coyotes have rabies. Nope!
All animals, us too, harbor pathogens. That's enough to scare me out of eating unusual food/animals. I still have some reservations of eating farmed animals, and even then I cook the $%^& out of it.
Yeah, drinking bat blood cures everything. NOT! I bet you could give them MY blood, and they wouldn't know the difference.
And besides, blood when it hits stomach acid, is probably mostly "cooked" by the acid and denatured. At that point, its just a meal of crude protein, minerals, and water. Isn't that the job of the stomach, to render food into something that the guts can work with?
So sad people are convinced that these old stories are true. No cure to be had in drinking bat blood.
I once got to see a bat flight event, out of a cave entrance around dusk. maybe 200,000+ swarmed out for over 1 hour. it was a natural wonder!
we were not allowed to take images, as the electronics in the cameras made sounds that were ultrasonic, and caused issues with bat navigation.
