Washing leafy greens does not remove all germs. That's because germs can stick to the surface of leaves and even get inside them. If you eat contaminated leafy greens without cooking them first, such as in a salad or on a sandwich, you might get sick.
Sometimes, raw fruits and vegetables contain harmful germs that can make you and your family sick, such as Salmonella, E. coli, and Listeria. CDC estimates that germs on fresh produce cause a large percentage of foodborne illnesses in the United States. The safest produce to eat is cooked; the next safest is washed.
Washing lettuce is primarily a matter of food safety: It helps to prevent bacteria like E. coli and other foodborne illnesses, which can be transferred to leaves through the soil, or through improper handling or transporting after harvest.
The answer: It's probably fine, but to be safe, wash (or re-wash) all lettuce before using it in your salad, whether it's straight from the garden or the supermarket shelf. Don't worry, washing and drying lettuce doesn't take as long as you might think if you have the right tools in place.
Consumers Union, on its website, advises consumers to go ahead and give those bagged, pre-washed greens an extra washing. The bottom line is — if you eat fresh lettuce, you're taking a small risk. An additional washing won't change the risk much, one way or the other.
In a word, no. According to James Rogers, Ph. D., director of Food Safety and Research at Consumer Reports, if E. coli (or any other type of bacteria that can cause food poisoning) is present in your produce, washing it won't remove all of those organisms.
The easiest way to clean your greens is to agitate and soak them in a large quantity of water. At the restaurant, that meant filling 10-gallon sinks with cold water to soak 20 heads of lettuce at a time. At home, just fill a large bowl or your kitchen sink.
Is It Better to Store Lettuce Washed or Unwashed? Head lettuce, such as iceberg and romaine, keeps fresh longer when it remains attached to the head and unwashed. Rinse the leaves only when you are ready to use them.
Do I have to wash pre-washed lettuce? The quick answer is: yes, you probably should wash pre-washed lettuce. No matter what the bag claims, pre-washed lettuce might not be as clean as you think. The Food and Drug Administration (FDA) encourages lettuce to be washed with a bleach solution to kill harmful bacteria.
Do I Need to Wash Lettuce? Yes, it's important to wash all fresh produce, but especially leafy greens and lettuce. Harmful bacteria from the soil can contaminate fruits and vegetables and lead to a foodborne illness if consumed.
Always wash lettuce to remove pesticides and contaminants—even wash bagged lettuce from the grocery store labeled “pre-washed” as an extra precaution. Washing produce is primarily a matter of food safety: It helps to prevent bacteria like E.
Rinse produce BEFORE you peel it, so dirt and bacteria aren't transferred from the knife onto the fruit or vegetable. Gently rub produce while holding under plain running water. There's no need to use soap or a produce wash. Use a clean vegetable brush to scrub firm produce, such as melons and cucumbers.
Packaged salads should be safe for consumption because their production must follow food safety practices. 2. Sometimes, packaged salads could be contaminated with harmful microorganisms. But that DOES NOT mean all of them are contaminated.
So, pre-washed greens are full of chemicals
Unfortunately, traces of the strong cleaners will linger on your lettuce and make it into your mouth if you're not careful. Since bleach—even diluted in water—is toxic in high quantities, it's best to re-wash your salad components yourself before you dig in.
Wash or Don't Wash Romaine Lettuce
If you're in a hurry, fresh romaine can be stored unwashed in a loosely closed plastic bag. If you prefer to wash it before putting it away, separate leaves from the heart.
The Rule is: Lettuce is washed in cold Water!
Pluck lettuce and wash it quite quickly in cold water, change the water several times if it is very dirty. The process should be completed in a maximum of 10 minutes.
Most types of E. coli are harmless or cause relatively brief diarrhea. But a few strains, such as E. coli O157:H7, can cause severe stomach cramps, bloody diarrhea and vomiting.
There are no antibiotics for most E. coli infections. If you have contracted traveler's diarrhea, your doctor may recommend that you do take anti-diarrhea medications for a short period or bismuth subsalicylate (Pepto-Bismol). In some instances, doctors treat the infection with antibiotics.
Most people infected with E. coli O157 do not have a fever or vomiting. Symptoms usually begin 2 to 5 days after exposure to the bacteria.
coli that can cause serious sickness in humans - can spread to salads and vegetables if they are fertilised with contaminated manure, irrigated with contaminated water, or if they come into contact with contaminated products during cutting, washing, packing and preparation processes.
Federal officials are reporting that a deadly multi-year outbreak of Listeria monocytogenes infections traced to romaine lettuce is over.
Pay Attention to the Use-By Date: Eat the lettuce as early as possible, and for sure earlier than the use-by date, in order to limit the time in which bacteria can multiply. Avoid Bags with Mushy/Slimy Leaves or Swollen Bags: These are all clues that there is a “bacteria party” going on!
