How Long Does a Head of Lettuce Last?
Whole head lettuce needs cool, protected storage. Purdue Extension recommends washing and thoroughly drying lettuce, then wrapping it in a dry towel inside a plastic bag in the refrigerator. Its approximate keeping period is an attributed household observation; Purdue does not classify its endpoint as quality or safety.
Quick answer
Purdue Extension's household method is to wash and thoroughly dry lettuce, wrap the dry head in a lint-free towel, place it in a plastic bag, and refrigerate. Avoid trapping excess water, which can speed breakdown. If the product's package gives a different method, follow that label.
The extension page says lettuce keeps about five days but does not classify that endpoint as safety or quality. Treat it as an approximate keeping observation, not a guaranteed deadline or a new allowance after purchase.
If you wash the head before storage, dry it thoroughly before wrapping. FDA recommends rinsing produce under running water before preparation or eating; do not wash produce with soap or detergent.
Washing and drying do not restart the storage history. Keep the lettuce refrigerated and use the package or extension directions for its state.
Place cut lettuce in a clean covered container and refrigerate promptly. FDA recommends keeping the refrigerator at or below 40°F (4°C); no lettuce-specific post-cut refrigerator duration is established here.
Once cut or prepared, refrigerate within two hours, or within one hour above 90°F (32°C). Cutting does not grant a fresh whole-head period.
Keep lettuce away from apples, pears, and bananas when possible. Illinois Extension notes these fruits release ethylene, which can cause lettuce to brown and decay more quickly.
This is a quality consideration, not a safety timer. It does not establish an additional refrigerator interval.
Discard immediately if
- Discard lettuce with visible mold, slimy decay, or other clear spoilage; do not use sensory checks alone to certify safety.
- If lettuce has been cut and left unrefrigerated beyond the FDA two-hour limit, or one hour above 90°F (32°C), discard it.
Why guidance varies
Crisphead, romaine, and butterhead lettuce differ in leaf structure and packaging. An intact head is not the same as a ready-to-eat bagged salad or loose prewashed leaves. Moisture, bruising, and ethylene from nearby fruit can affect quality, while cut or prepared lettuce needs separate handling.
An intact head is different from bagged salad
Covers intact crisphead, romaine, or butterhead, not bagged salad. Check the package and remove bruised outer leaves.
Keep lettuce cold and avoid trapped water
Purdue Extension's method: wash and thoroughly dry, wrap in a dry lint-free towel, bag, and refrigerate. Its approximate five-day observation is not a safety endpoint or guarantee. Washing does not reset storage history. For unwashed storage, keep dry, follow the package, and rinse before cutting or eating; do not use soap.
Separate cut leaves and keep fruit away
After cutting, cover and refrigerate promptly; the whole-head estimate does not apply. Keep the refrigerator at or below 40°F (4°C). FDA's general limit is two hours out, or one hour above 90°F (32°C). Ethylene from apples, pears, and bananas can speed browning, a quality effect.
Use hygiene and spoilage signs together
Separate lettuce from raw meat and seafood. Wilt or dry edges affect quality; discard moldy, slimy, or rotten leaves. Normal smell cannot prove safety. Freezing harms crisp texture.

Frequently asked questions
How do you store a whole head of lettuce?
Purdue Extension recommends washing and thoroughly drying it, wrapping it in a dry lint-free towel, putting it in a plastic bag, and refrigerating. Follow package directions for packaged products.
Should I wash lettuce before storing it?
Purdue's method washes and dries lettuce before storage; Illinois Extension also describes wrapping fresh unwashed leaves. Whichever method you use, keep the lettuce cold and avoid storing it wet. Rinse before eating if it has not already been washed.
How long does a head of lettuce last in the fridge?
Purdue Extension says about five days for its household method but does not identify a safety endpoint. Variety, freshness, moisture, and handling change the result; use this as a keeping observation, not a guarantee.
Can I freeze lettuce?
Lettuce's high water content makes freezing a poor choice for fresh crisp texture. No home freezing method for salad-quality lettuce is established in the sources reviewed.
