How long will raw tripe stay fresh at room temp?

Raw tripe should not be left at room temperature for more than 2 hours, as bacteria can grow rapidly at temperatures between 40°F and 140°F (4°C to 60°C). If the room temperature is above 90°F (32°C), this time decreases to just 1 hour. To ensure safety, it's best to refrigerate or freeze raw tripe if not cooking it immediately.
