I disagree with that statement generally, but anyway, you can’t catch cancer. You can catch a disease that causes cancer, but eating cancer itself wouldn’t give you cancer. You can however catch prion disease… And these can live in real flesh/meat you get from a shop.
Also, there will be ground up cancer in processed meat. I guarantee it. You don’t think farm animals get cancer?
Christ. New horrors beyond my imagination.
Still, my point stands that there are already risks to animal agriculture. Tasmanian devil cancers don’t make this a no go IMO.
(I am aware that’s not what you are suggesting)
