Two factors to consider id say. Blood isn't the only organic source of nitrogen so it's not as if its necessary, thus I'd wager many vegans would consider it unnecessary animal suffering, at least in theory. However the caveat, and second factor, would be blood is byproduct, no ones killing the animals in order to obtain blood meal so many people including vegans may think it more ethical to not let it go to waste since weather or not there's a demand for blood meal, there will still be animal blood that needs to be disposed of.

Strictly dietarialy, yes they would still be vegan. All soil is full of countless formless decomposed animals and plants, it's an inescapable reality of how the soil came to be. It can only get more ethically involved when you choose to add it yourself imo.

There are vegan blood meal alternatives out there to resolve this exact conundrum.

But the reality is, unless your plants are being grown hydroponically in a sealed warehouse or similar, chances are real good that they are feeding on decaying animals (either directly or indirectly) whether you like it or not. They're mostly insects and annelids and such, but still animals.

I think the issue for vegans is more about whether animal slaughter was involved in making their fertilizer. Dead pillbugs in the soil is just nature doing its cycle of life thing.

Also it's good to let people know because dogs absolutely love that shit and you have to be careful to keep it out of areas dogs can get at it.

I worked in a green house and one customer's dog dug up an entire tree she planted to get at the blood meal she put in the bottom of the hole. Dog was okay, but needed to stay at the vets a few days to monitor the vomiting and their iron levels.

Our dachshund picks up and eats all kind of shit. She's a destroyer of SHOES and CPAP masks, of course, but she also eats rocks, plastic, or whatever else she finds.

The other day I walk in, and she has 2 milkbones (we don't buy them and I have no idea where they came from). She just moved them around for a few days and never ate them. But a stick is fine dining.

Dogs are weird.

This is what I came here to say. The clarification on the post is not about humans eating plant food, it's about idiot fucking pets eating plant food. They eat grass, why wouldn't they chow down on something that smells like blood.

Uhm, hello, it says blood MEAL, so of course it's made to be eaten.

Sure, but you'd need a lot.

Sweden, Ireland, France, Spain and Italy also use them for sausage-like products (these I know of, I'm sure there's more)

Ya, I assumed this was like instant mash for blood pudding. Probably would have second guessed it if I saw it in the gardening aisle, though.

No, you can find this in garden shops in Europe.
