In this context - why is beef different from sushi or ceviche ? As to beef perfectly safe to eat raw - good luck with that!
Sushi on the other hand usually contains raw fish indeed, which is why it should only be eaten fresh.
As for cooking beef, there’s certainly a reason why our ancestors invented cooking. It helps with making food more palatable and safer to eat. When heating tissue above roughly 42 degrees centigrade proteins start to denature, which renders many pathogens inactive and harmless.
The gastrointestinal system of modern humans can’t stomach many types of foods raw either because we lack the enzymes to digest them.
So perhaps not perfectly safe?
On the other hand, there are dishes like steak tartare, which, if not eaten too frequently, probably and usually won't cause any harm.
Absolutely - and this is exactly my point, everyone knows this. There is no point in gods telling humans what not to eat because humans know this already, known this for millennia. Religious prohibitions on food have nothing to do with "health and safety" and everything to do with manipulation and control,
