Lettuce lasts one to two weeks

Lettuce lasts one to two weeks, When you buy a head of lettuce at the store, it should keep, intact, for about two weeks. But once you open up the head and cutup the lettuce, it will start to spoil faster. “That’s because you’re exposing the interior of the lettuce,” says Allen.

And that releases nutrients for bacteria to feed on, and causes leaves to brown due to being exposed to oxygen. Those leaf lettuces that are contained in special modified atmosphere packaging can last longer than a head you cut up because they are better protected from oxygen and bacteria exposure. lettuce lasts one to two weeks,
