Can I still eat my bean sprouts that I left unrefrigerated?
Raw bean sprouts are considered to be a potentially hazardous food item or a TCS  food (time-temperature control for safety). Bean sprouts are likely to become unsafe due to bacterial growth if left un-refrigerated for more than four hours, as a warm, moist environment promotes bacterial growth. To err on the side of caution, you should throw your bean sprouts away.
