Questions: What is the highest temperature allowed for cold-holding turna salace? a. 41 degrees F (5 degrees C) b. 50 degrees F (10 degrees C) c. 59 degrees F (15 degrees C) d. 68 degrees F (20 degrees C)

The answer is the first one (or A): $41^{\circ} \mathrm{F}\left(5^{\circ} \mathrm{C}\right)$.

Explanation for each option: a. $41^{\circ} \mathrm{F}\left(5^{\circ} \mathrm{C}\right)$ - This is the correct answer. According to food safety guidelines, cold foods should be held at or below $41^{\circ} \mathrm{F}\left(5^{\circ} \mathrm{C}\right)$ to prevent the growth of harmful bacteria.

b. $50^{\circ} \mathrm{F}\left(10^{\circ} \mathrm{C}\right)$ - This temperature is too high for cold-holding. It falls within the danger zone where bacteria can grow rapidly.

c. $59^{\circ} \mathrm{F}\left(15^{\circ} \mathrm{C}\right)$ - This temperature is also too high and is well within the danger zone for bacterial growth.

d. $68^{\circ} \mathrm{F}\left(20^{\circ} \mathrm{C}\right)$ - This temperature is far too high for cold-holding and would allow bacteria to multiply quickly.

Summary: The highest temperature allowed for cold-holding tuna salad is $41^{\circ} \mathrm{F}\left(5^{\circ} \mathrm{C}\right)$. This ensures that the food remains safe to eat by minimizing the risk of bacterial growth.
