The maximum cold holding temperature allowed for shredded lettuce is 41°F (5°C) or below. This temperature limit is set to inhibit bacterial growth and ensure food safety, as shredded lettuce is considered a high-risk, time/temperature control for safety (TCS) food. Maintaining shredded lettuce at or below 41°F helps prevent contamination and spoilage, consistent with FDA Food Code guidelines and food safety best practices for cut leafy greens
