What is the highest temperature for cold holding tuna salad?

The highest temperature for cold holding tuna salad should not exceed 41°F (5°C) according to food safety guidelines. Keeping perishable foods such as tuna salad within this temperature range helps prevent the growth of harmful bacteria that can cause foodborne illness. It is important to use a refrigerator or cooler with a thermometer to monitor and maintain the proper temperature for storing tuna salad. Additionally, it is recommended to discard any tuna salad that has been left out at room temperature for more than 2 hours to reduce the risk of foodborne illness.
