Can you get sick from eating old lettuce?

In this short article, we will provide an answer to the question “Can you get sick from eating old lettuce?” and the information on storing lettuce.

Can you get sick from eating old lettuce?

Yes! It is possible to get gastrointestinal symptoms after eating old or bacteria-laden lettuce. This is since damaged lettuce can harbor harmful germs such as E.coli, Salmonella, and Listeria. 

Consumers’ Attitudes Toward Lettuce and Food Safety

According to the Centers for Disease Control and Prevention, raw lettuce and sprouts are common sources of E. coli, a bacteria that can cause food poisoning. In addition to diarrhea, severe stomach cramps, vomiting, and fever are also common symptoms of E. coli infection. After consuming tainted food, symptoms usually show three to four days after consumption, and people begin to feel better in five to seven days.

Following the Food and Drug Administration’s food safety guidelines will help you prevent developing foodborne illnesses. Maintain the cleanliness of your hands, utensils, and food preparation surfaces at all times. Cleaning fresh fruits and vegetables with a clean brush after washing them under running water is always recommended.

The separation of raw meat and fish from fresh produce, particularly produce that will be consumed uncooked, is another critical food safety rule. Make sure all of your food, including raw meat and seafood, is correctly stored to avoid illness. Use leakproof containers to keep raw meat and seafood to avoid infection.

Brown Lettuce and the Risk of Food Poisoning

According to scientists, there is no obvious link between eating dark lettuce and the risk of contracting a food-borne disease. Lettuce leaves can become brown when bruised or cut, according to Berkeley Wellness, due to the oxidation generated by the presence of air in the environment. According to the University of California Statewide IPM Program, tipburn is another cause of lettuce browning, and it is typically caused by rapid growth or soil water stress in the plant.

Also known as russet spotting, this process is responsible for the appearance of brown or black patches on lettuce. In the presence of low quantities of ethylene (a plant hormone that is generated as a gas), this happens to lettuce. ethylene exposure causes the production of phenolic compounds, which results in the brown or black patches on lettuce that may be seen.

However, russet spotting is a cosmetic issue that can be easily resolved. If the brown or black spots on lettuce are accompanied by a strange smell or texture that prompts you to assume the problem isn’t just russet spotting, toss it out rather than eat it and call the produce department.

What is the deal with pink lettuce?

Rose-colored lettuce is connected with a condition known as pink rib, which occurs when the “ribs” of lettuce heads turn from white to a rose-colored shade of pink. This can occur when lettuce is “overmature” or when it is stored at high temperatures.

What is the best way to know whether your lettuce has gone bad?

A few obvious indicators that your lettuce has gone bad can be found on its leaves. Look at the appearance, texture, and smell of the lettuce to decide if it has gone rotten or is still good.


The degeneration of your lettuce (a brown tint) suggests that it has passed its prime.


Throw aside your lettuce if it’s become soft or has a slimy feel after being stored for a long time. Aside from that, when a lettuce salad with dressing becomes sloppy, it implies that the lettuce salad is bad.


If you notice an off-odor (rotten or sour) or something that does not smell quite like fresh lettuce, it is likely that your lettuce has gone bad and should be thrown out immediately.

What are some practical suggestions for keeping lettuce?

Lettuce should be stored in the refrigerator at temperatures no higher than 40 degrees Fahrenheit.

You should properly wash and then cover the lettuce head in damp paper towels and plastic wrap after blotting it dry with a paper towel after it has been dried. Alternatively, you can store the lettuce head in a plastic zipper bag that has been wrapped in damp paper towels.

It is not recommended to keep lettuce near fruits such as bananas or apples because these fruits produce ethylene, which accelerates the ripening process and causes the lettuce leaves to yellow. Furthermore, it causes lettuce to become extremely soft and mushy, lowering the shelf life of the produce.

If you want to keep the lettuce salad, don’t dress it with any dressing before putting it in the refrigerator.

Your lettuce may become contaminated with bacteria and other microbes if it is left on the kitchen counter for longer than 2 hours.

A good rule of thumb is that lettuce should not be kept in the freezer.
