Probably not. Warm temperatures increase spoilage speed of foods.
Beef tamales are at risk of bacterial growth when left out at room temperature overnight. A good idea if still interested in eating is to reheat in the microwave to kill any microorganisms.
Yes
naaahhh
No, its not.
It is unsafe to eat any meat that has been left between 40F-140F for more then two hours.
This little piggy had roast beef, but that little piggy had none. There are none left.
No it should be refrigerated to keep bacteria away.
That depends on how it is stored or wrapped. In an airtight container about 3 to 4 days. If just in a plastic bag about 2 to3.
Fore rib is a cut of beef. It comes from high on the animal, near the midline (feel where your own ribcage ends, move your hand towards your spine and this will give you an idea where the joint comes from). Fore rib is a joint that can either be boned out and rolled, then roast, or it can be left and cooked 'on the bone' - this is what is traditionally served as British roast beef.
'Pot liquor' is the liquid left in a covered roasting pan or pot, after cooking. A good example is a pot roast of beef- the roast is cooked with vegetables, spices, and either water or beef stock (stock is much better). The roast is cooked for several hours. The resultant 'pot liquor ' is the remaining liquid- essentially reduced, or wonderfully strong flavored beef stock! It may be used as a thin gravy over the vegetables, the meat or anything you would use gravy on. It may also be thickened, but then it IS gravy.
No, it is not safe - unless where it was sitting was as cold as a refrigerator.
No one can answer that for you. Potentially hazardous food should not be allowed to defrost overnight at room temperatures. If you cook it, you do so at your own risk.
