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.
Boiling for 30 seconds destroyed 91% to 93% of bacteria, a minute raised the kill rate to 96% to 98%, and two minutes of heating eradicated 99%. Microwaving showed similar numbers. Finally, the spinach was heated for four minutes, at which point no signs of live bacteria showed up in the Petri dishes.
Use plain running water to wash leafy greens and other produce. Kitchen vinegar and lemon juice may be used, but CDC is not aware of studies that show vinegar or lemon juice are any better than plain running water.
Studies suggest that acetic acid, found in vinegar, and citric acid, found in lemon juice, may be particularly effective at killing some types of bacteria, such as E. coli, on leafy greens (5, 6, 7).
E. coli O157:H7 in spinach can be killed by cooking at 160° Fahrenheit for 15 seconds. (Water boils at 212° Fahrenheit.) If spinach is cooked in a frying pan, and all parts do not reach 160° Fahrenheit, all bacteria may not be killed.

'Soap doesn't kill anything'
It's not intended to kill microorganisms,” Claudia Narvaez, food safety specialist and professor at the University of Manitoba, explained to CTVNews.ca. “It will kill some bacteria, but not the ones that are more resistant to environmental conditions, like salmonella or E. coli.”
Handwashing with soap is an effective and economical means to reduce the likelihood of Escherichia coli infection from indirect contact with contaminated surfaces during food preparation.
While vinegar, as a mild acid, is a great cleaner and does kill some pathogens, it is not a registered disinfectant. Specifically, vinegar can kill salmonella, E. coli, and listeria, which is good news for the kitchen.
Their presence on fresh produce is not uncommon. Salmonella, E. coli O157:H7, Campylobacter jejuni, Vibrio cholerae, parasites and viruses can contaminate produce through raw or improperly composted manure, irrigation water containing untreated sewage or manure, and contaminated wash water.
To kill the germs in your laundry, wash your clothes on the hot cycle, then put everything in the dryer for 45 minutes. Wash whites with bleach, and use peroxide or color-safe bleach for colors. Do your laundry in water that's at least 140 F to kill any viruses or bacteria.
Drink plenty of clear liquids, including water, clear sodas and broths, gelatin, and juices. Avoid apple and pear juices, caffeine, and alcohol. Avoid certain foods. Dairy products, fatty foods, high-fiber foods or highly seasoned foods can make symptoms worse.
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.
Make sure to wash your vegetables, or cook them to kill the bacteria whenever possible. Correction - September 6, 2022: This article was updated to reflect the correct symptoms of Lauren Bush while she had an E. coli infection. Centers for Disease Control and Prevention.
Wash spinach before eaating to remove trapped sand. Without thoroughly washing spinach before eating, your meal will likely feature the unwanted taste and texture of gritty sand in each bite.
TORONTO -- Fecal matter from your dirty underwear is probably still lurking in your fresh laundry, according to multiple studies. Even worse, one microbiologist has found that bacteria such as E. coli can survive the average laundry cycle.
Depending on the type of fabric, bacteria can survive from several days to over six months. They live longer on cotton than on polyester blends because cotton is more absorbent.
Essential Oils
Adding 2 teaspoons of 100% tea tree oil is all you need to disinfect your laundry. A few drops of lavender oil act as an antibacterial element for your clothes and thyme oil has been known to kill E. coli and MRSA, so it will certainly remove any foul-smelling odors from your fabrics.
Dishwashers and hand washing rarely generate water that is hot enough to kill E. coli. The Kent County Health Department recommends rewashing any dishes with water that has been boiled for at least one minute, then cooled down, or bottled water.
Symptoms include diarrhoea, stomach cramps and occasionally fever. About half of people with the infection will have bloody diarrhoea. People usually notice symptoms 3 to 4 days after they have been infected. But symptoms can start any time between 1 and 14 days afterwards.
Research shows that E. coli, Salmonella and Staph can thrive on dishes and other kitchen surfaces. Whether putting away groceries or rinsing fresh vegetables, even the most careful cook can pass bacteria to new kitchen surfaces through the simple process of preparing a dish.
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.
While romaine lettuce has been associated with several E. coli O157: H7 outbreaks, iceberg lettuce has been less frequently associated with outbreaks caused by shigatoxigenic E. coli.
Wash all leafy green vegetables, including pre-bagged greens under cold running tap water. For leafy vegetables, such as lettuce and cabbage, remove the outer leaves first. Throw away any wilted or discoloured leaves.
