Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).
Opened canned tuna should be refrigerated promptly after serving or within the specified room temperature limits to prevent bacterial growth.
Safe Handling
Always wash hands thoroughly with soap and water before and after handling food.
Once opened, transfer tuna from the can to a separate airtight container for refrigeration.
Do not consume tuna from cans that are bulging, leaking, severely dented, or rusted, as this may indicate spoilage or botulism.
