Can you still cook a roast that was left uncooked in crock pot for 11 hours?

It is not recommended to cook a roast that has been left uncooked in a crock pot for 11 hours. The USDA recommends that food be cooked to a safe internal temperature to prevent the growth of harmful bacteria. Leaving meat uncooked in a warm environment for an extended period of time can increase the risk of foodborne illness.

If you are unsure about the safety of a food item, it is always best to discard it.
