The short answer: Throw it out.
The FDA recommends discarding any fresh, cooked or leftover chicken, turkey, beef or steak if the meat has been held above 40 degrees for over two hours.
This includes seafood; salads with chicken, tuna or eggs; pizza with any toppings; and any opened canned meats or fish.
Use the "40 degree rule" to discard soft and shredded cheeses (cottage cheese, cream cheese, Monterey Jack, ricotta).
Hard cheeses (cheddar, Colby, Swiss, Parmesan, provolone, Romano) and processed cheeses can last up to four hours before needing to be thrown out.
Milk, creams, yogurt and baby formula should be thrown out using the "40 degree rule."
Butter and margarine are safe in the fridge for up to four hours.
Like meat, eggs (including hard-boiled), custards and egg products should be thrown out once held at a temperature of 40 degrees for at least two hours.
Use the "40 degree rule" to discard cooked pasta, pasta salads, cookie dough, refrigerated biscuits and cheesecake.
Loaves of bread, muffins and breakfast foods can last longer either in the fridge or on the counter.
Fresh-cut fruit should be discarded once the "40 degree rule" applies.
Opened apple juice, orange juice, canned fruit, raisins and dried fruit should be fine for up to four hours.
Throw away cooked vegetables, tofu and soups once they've been held to a temperature of 40 degrees for at least two hours.
Raw veggies and mushrooms can last at least four hours in 40 degree temperatures.
