Q: Is ingesting other people's blood harmful?

Submitted by hjek in Vegan (edited )

I was making a vegan cake for some carnist friends. While chopping fruits, I accidentally cut my finger. Some blood came out, but only after I'd stepped away from the chopping board with the fruit on it. My friends insisted that I had to throw out the cake dough, because of the hygiene risk, which I thought was strange, given that they themselves eat flesh on a daily basis. They even suggested that the dough may have been contaminated through the air.

Is there any reason to believe that it's more dangerous in any way to ingest human blood that non-human blood, or is this pure speciesist irrationality?

Weird story; I have vegan friends who have made and eaten black pudding out of each other's blood.

You can draw blood out safely, and you can consent to having your blood eaten. Soooo yeah.

Years ago I read some vegan forum that had a recipe for black pudding made from your own blood. Never did it, felt like too much trouble but I guess I would be one of those weirdo that would try it out, I thought it was a genius idea.

That's interesting. Perhaps there's something intrinsic to veganism / anti-speciesism that makes people less fearful of consensual blood consumption?

Dont eat raw human blood, imo it is worse than raw animal blood because humans are more likely to carry stuff that will harm other humans.

Cooked human blood is a delicious and ethical way to get proteins!

Bacteria don't travel by air AFAIK. When I cut myself I only wash/rinse the blood off for cooked stuff and cut off what touched it for raw stuff.

This cake was going in the oven, so the blood would've been cooked.

Prions causing variant Creutzfeldt-Jakob disease (vCJD) are not destroyed by cooking and are thought to be transmissible by blood. This is why people who come from areas where there have been outbreaks of vCJD are forbidden from giving blood.

That being said, as far as I know, vCJD is incredibly rare, even more so outside of the UK and Europe. And the concentration of prions in contaminated human blood is so low as to be barely detectable. Therefore, the disease's transmissibility through blood is contested.

I can't imagine that the accidental ingestion of one drop of cooked human blood would pose any credible risk to one's health.
