Cooked all the way through. When i was preg with DD1 I ordered a burger at a pub. That meat pattie was pink, so I called over the waitress to get another. Her response was that I did not ask for well done. Well I went off and explained to her that mince has to always be cooked, that I had never had to ask for a well done burger in my life as it should be cooked through in the first place. Also went on that I was pregnant and if I lost the baby due to this, the pub would be in trouble. She quickly took back the meal and got me a another fully cooked one.
