ELI5: Why is spoiled food dangerous if our stomach acid can basically dissolve almost anything organic

Pretty much the title.

If the stomach acid is strong enough to dissolve food, why can't it kill dangerous germs that cause all sorts of different diseases?

Not all bacteria go down to the stomach, some stay in your mouth.

Bacteria can also produce toxins on the food while it spoils, even if the stomach acid kills the bacteria, the toxins can still poison you.

Also some bacteria are just acid resistant.
