Pantry

Not Recommended

Not recommended

Lettuce requires refrigeration to maintain freshness and safety. Do not store at room temperature for extended periods.

Refrigerator

7-10 days

Store whole, unwashed lettuce in a plastic bag or airtight container in the crisper drawer of the refrigerator. Wash just before use.

Freezer

Not Recommended

Not recommended

Freezing is not recommended for whole lettuce as it becomes limp, watery, and loses its texture upon thawing.

Signs of Spoilage

  • Wilting or limp leaves
  • Slimy or mushy texture
  • Brown or black discoloration on leaves
  • Off-odor or sour smell
  • Visible mold growth

Room Temperature Safety

Follow the 2-hour rule: Do not leave perishable foods, including lettuce, at room temperature for more than 2 hours. If the ambient temperature is above 90°F (32°C), the limit is 1 hour.

The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).

Promptly refrigerate lettuce to prevent the growth of harmful bacteria. Discard any lettuce left in the danger zone for too long.

Expert Tips

Safe Handling

1

Wash hands thoroughly with soap and water before and after handling fresh produce.

2

3

Remove any outer leaves that are wilted or discolored.
