I cooked corned beef and cabbage with potatoes carrots in the oven covered foil. Then forgot left it overnight. Is still ok to eat?

According to the USDA, cooked food should not be left out at room temperature for more than two hours. This is because bacteria can grow rapidly at room temperature, and can cause food to become unsafe to eat.

Here is some information to help you assess whether your corned beef is still safe to eat:

* If it has been more than 8 hours since the corned beef was cooked and left out at room temperature, it should be discarded.

* If it has been less than 8 hours since the corned beef was cooked and left out at room temperature, it may still be safe to eat. Look for signs of spoilage, such as:

* An off odor

* A slimy texture

* A change in color

* You can also reheat the corned beef to an internal temperature of 165°F to kill any bacteria that may be present.

If you are unsure whether your corned beef is safe to eat, it is best to err on the side of caution and discard it.
