ELI5 - If chicken or pork is sold “pre-cooked,” why does the package say to cook it to an internal temperature of at least 165 degrees?

The factory does its best to make sure food is packaged ASAP after cooking to ensure no bacteria gets on it. If you aren't careful and/or let this food get back into the "danger zone" for a length of time, bacteria can start to grow again. So:

* Giving the food one last reheat makes extra sure you've gotten rid of that bacteria and the food is safe.
* Telling you to do that makes the company less liable (both legally and ethically) if you ignore the warning and get sick.
* Warm food tastes better.
