Left raw meat out overnighthelp!

Last night when I got home from the grocery store, I put the bag with the meat--a beef roast and a large package of chicken thighs--on the dining room table to transfer to the back refrigerator. I finished bringing the groceries in and then forgot to follow through with putting the meat up. It had been sitting out at room temp for ~16 hours when I discovered it (including transit time from the grocery case). If I use it right away, is it still good, or do I chuck it all? The chicken thighs were to be used for making stock and then freezing. Please help--don't want any risk of making someone sick. ~pen
