You can store marinated poultry in your refrigerator for 2 days. Beef, veal, pork, and lamb roasts, chops, and steaks may be marinated up to 5 days.(From http://www.foodsafety.gov/blog/marinades.html).'ve had this just overnight from a soy and ginger marinade with beef. In general though I would think that the beef will be ok, but I would be less certain about the chicken. It probably depends on how fresh the meat was in the first place. Smell it and look at it.
