Use minced beef, since it is entirely obviously when it has been made safe (it will turn brown). Always use a clean knife, cutting board and hands for meat and things that come from the ground.

Also experiment with roasting things in the oven because with a cooking thermometer that's pretty much fool proof in terms of safety.

Finally consider a slow cooker/Instapot. Cook things for 8 hours and everything is safe to eat if it ever will be.
