25. Ground duck must be cooked to an internal temperature of 135^circ F(57^circ C) 145^circ F(63^circ C) 155^circ F(68^circ C) 165^circ F(74^circ C)

The correct answer is $165^{\circ }F(74^{\circ }C)$. Ground duck must be cooked to an internal temperature of $165^{\circ }F(74^{\circ }C)$ to ensure it is safe to eat. This temperature is recommended by food safety guidelines to kill any harmful bacteria that may be present in the meat.
