I once got food poisoning eating someones home cooked pork ribs and it was one of the nastiest experiences! I am always a little over cautious haha
I know cooking kills bacteria but I am going with the United States Department of Agriculture and USDA.gov food safety standards where they say not to leave uncooked food at room temp for more than two hours...
I am sure they are way over cautious and beef is a little more forgiving then pork or chicken but I would rather be safe than sorry. I know I am food paranoid!
Chris: if you see this, do we have a food safety section on the website? I looked but with so much info I could of easily overlooked it!
