No more than one hour. Left without refrigeration too long and the food begins to spoil, which means bacteria start forming that could make you ill if you ate tainted food.
Cooked meat should not be left at room temperature for more than 2 hours.
No.
yeah of course it can stupiD!
That depends how long it was left out of the refrigerator - hopefully not more than an hour or maybe two. If you are uncertain, don't eat it.
This can spoil if not kept in the refrigerator. Keep it in an airtight container to prevent drying out. It can last up to a week in the refrigerator.
If you are talking about uncooked ears of corn that were left out of the refrigerator overnight, some of the sugars have probably changed to starches so it won't be so sweet. But it should be OK to cook up and eat. If you are talking about cooked corn that someone forgot to put away, the answer is "No. You should not eat cooked corn left out overnight."
No it should be refrigerated to keep bacteria away.
Nope. Once it is opened it needs to be put in your refrigerator, cooked or not.
Meats are kept better in the freezer. Meats can be kept in the refrigerator for 3 to 4 days if raw and 1 to 2 days longer if cooked. Always place cooked meats in an airtight container.
Yes, That cabbage is very good if you have corned beef and potatoes w/ it!
If they have been fully cooked all the way through, and do not contain moist fruit, then maybe they could be left out and still be safe - like baked bread - but it is probably better to refrigerate them.
Not if it should have been kept refrigerated.
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.
