Cow muscle tissue is dense and difficult for bacteria to penetrate, with a single surface area (the outside) assuming safe handling and “edible freshness”. So cooking the outside to “rare” offers protection by cooking off surface or lightly penetrated bacteria.
Ground beef is soft and porous, with a massive surface area, much easier for bacteria to penetrate completely.
However, that aside, your analogy has a sound basis: more input sources = higher opportunity for corruption.

That’s not the reason.

Well hey I appreciate it, I genuinely thought what i wrote was the whole thing, I’m glad to know that there’s more, and the details behind it.
