If I left my coffeemate out overnight should throw away?

Yes, it is recommended to throw away coffee creamer that has been left out overnight. Coffee creamer typically contains dairy products, which can spoil and become unsafe to consume if left unrefrigerated for an extended period. The ideal storage temperature for coffee creamer is below 40°F (4°C). Leaving it out overnight at room temperature creates favorable conditions for bacterial growth, and consuming spoiled coffee creamer can lead to foodborne illnesses.

In general, it is best to follow the storage instructions provided on the packaging of any perishable food or beverage to ensure their safety and quality.
