Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).
To maintain safety and quality, iceberg lettuce should be refrigerated promptly and not left at room temperature for extended periods.
Safe Handling
Wash hands with soap and water for at least 20 seconds before and after handling fresh produce.
Wash iceberg lettuce thoroughly under cool running tap water just before eating, cutting, or cooking. Do not use soap or detergents.
Remove any outer leaves that are damaged or discolored.
Prevent cross-contamination by keeping lettuce separate from raw meat, poultry, and seafood.
