Does boiling soup to kill bacteria?
It’s a basic fact that every cook should know: bacteria that cause illness inevitably end up on nearly every ingredient we cook with, and even boiling won’t kill all of them. Boiling does kill any bacteria active at the time, including E. coli and salmonella.
How long do you have to boil something to kill bacteria?
The standard recommendation for boiling water is a FULL ROLLING BOIL for ONE MINUTE and COOL BEFORE USE. The term rolling boil facilitates communication and assures that an effective pasteurization temperature is reached to kill or inactivate waterborne pathogens.
Is simmering enough to kill bacteria?
The World Health Organization (WHO) notes that bacteria are rapidly killed at temperatures above 149°F (65°C). This temperature is below that of boiling water or even a simmer.
Is it OK to eat soup left out overnight?
Soup or stew left out for more than two hours (including overnight) should be discarded according to the USDA. Even if you reheat it to kill bacteria, there may be toxins made by the bacteria, which reheating can’t destroy. This applies to all soups and stews, with or without meat.
At what temp is bacteria killed?
Bacteria multiply rapidly between 40 and 140 degrees. Bacteria will not multiply but may start to die between 140 and 165 degrees. Bacteria will die at temperatures above 212 degrees.
How long can you boil soup for?
Add them to the pot raw, so they can release flavor into the soup. Bring it all to a boil, then simmer. You will know it’s done when it’s all tender, anywhere from 25 minutes to 3 hours depending on the ingredients.
Does reheating leftovers kill bacteria?
Proper heating and reheating will kill foodborne bacteria. However, some foodborne bacteria produce poisons or toxins that are not destroyed by high cooking temperatures if the food is left out at room temperature for an extended period of time.
How long do you have to boil water to kill E coli?
coli O157. Removing it from drinking water: Boil your water for 1 minute (at elevations above 6,500 feet, boil for 3 minutes) or disinfect it using chemicals. Specially designed filters and other water treatment technologies might also be effective.
Is E coli killed by cooking?
The good news is, E. coli and many other harmful bacteria can be killed by cooking food properly. Food safety tip: Because ground beef can turn brown before disease-causing bacteria are killed, use a digital food thermometer to make sure you cook hamburger to an internal temperature of at least 71°C (160°F).
What bacteria Cannot be killed by cooking?
Staphylococcus aureus
aureus is allowed to grow in foods, it can produce a toxin that causes illness. Although cooking destroys the bacteria, the toxin produced is heat stable and may not be destroyed.
Can you leave broth out overnight?
No matter how tempted you may be or how many times you’ve dodged the bullet, you can’t save broth that sat at room temperature for more than two hours. Remember: Broth is cheap, and toxins are vicious.
Can food bacteria be killed by cooking?
You can kill bacteria by cooking poultry and meat to a safe internal temperature . Use a cooking thermometer to check the temperature. You can’t tell if meat is properly cooked by looking at its color or juices. Leftovers should be refrigerated at 40°F or colder within 2 hours after preparation.
How do I know if my soup is spoiled?
1 The soup tastes and smells sour, and it shouldn’t.
If it tastes sour and it shouldn’t, it’s a good guess that your soup has spoiled. You may not want to taste it so use a spoon and give a spoonful of it a sniff instead. If it smells sour or otherwise off, this is another sign as well that it may have spoiled.
How long should soup cool before refrigerating?
The food danger zone is that place between 40 and 140 °F where pathogens grow most quickly. It can take a long time to get through the danger zone when cooling a large batch of chili, soup or stew. The soup must cool from 140 to 70 °F in 2 hours and from 70 to 40 °F in no more than 4 hours.
Should you put hot soup in the fridge?
A large pot or container of food that is hot should not be placed in the refrigerator or freezer. The hot food can raise the temperature inside the refrigerator/freezer which can be a risk for food already in the appliance.
What happens if you boil soup?
Their unique flavors require a slower cook time in order to give the varied ingredients time to mingle and meld. As such, you want to avoid cooking the soup over high heat, causing it to boil harshly. If you do, the flavors in your soup may become too concentrated as the liquid evaporates too rapidly.
Is it bad to boil soup?
Boiling is just too abrasive for soup. Simmering allows your soup to gently release flavors from the ingredients which means all sorts of good things. This.
Is it OK to boil soup?
‘” And though even a stock left out for days at a time might not technically be toxic after a thorough boiling, its flavor will certainly be compromised: A reboiled three-day-old stock may be safe to eat, but it is now seasoned with millions to billions of dead bacteria and their inactivated toxins.
How many times can you boil soup?
Don’t reheat a portion more than once—just take out what you will eat and keep the rest of it cold. A handy rule to remember is that if you are reheating a chicken or meat broth or clear soup, bring it to a boil for three minutes to be sure of killing off any harmful bacterial growth.

Bending the Rules on Bacteria and Food Safety
PEPPERED as we are by government warnings about the potential health hazards of eating and drinking just about everything, it was refreshing (and perplexing) to see a widely respected food writer assert recently that “people are unnecessarily afraid of bacteria” in the kitchen.
In April, Michael Ruhlman, author of “Ratio” and “The Elements of Cooking” and co-author of books by Thomas Keller and other chefs, said on his blog that he likes to make chicken stock and leave it out on the stovetop all week, using portions day to day to make quick soups and sauces.
But what about the harmful microbes that could grow on foods if they were not kept either chilled or hot? “Once your stock is cooked, it’s safe to eat,” Mr. Ruhlman wrote. “If there were bad bacteria in it, you’d have killed them.” After the stock has cooled, simply reheat it, he continued, and “any bacteria that landed there and began to multiply will be dispatched well before the stock hits a simmer.”
Boil Water Response-Information for the Public Health Professional
Boil Water Response – Information for the Public Health Professional
Boil Water Orders and Notices are often used by health agencies and drinking water utilities in response to conditions that create a potential for biological contamination in drinking water. Common reasons for a boil water response include loss of pressure in the distribution system, loss of disinfection and other unexpected water quality problems. Often these result from other events such as water line breaks, treatment disruptions, power outages, floods and other severe weather.
The standard recommendation for boiling water is a FULL ROLLING BOIL for ONE MINUTE and COOL BEFORE USE. The term rolling boil facilitates communication and assures that an effective pasteurization temperature is reached to kill or inactivate waterborne pathogens. Some agencies recommend boiling for longer periods, but this extra time is not necessary and can cause unnecessary power demand and increase safety concerns.
Because some users (e.g. immunocompromised individuals) may be more susceptible to illness from water borne pathogens, public health officials need to react swiftly to address potential water quality problems. However, public health officials must also be conscious of unnecessarily alarming the public, causing undue economic disruption, and eroding the public perception of safe tap water. Whenever possible, alternate methods to address water quality concerns, such as isolating problem water and opening interconnections with neighboring systems, should be used to avoid unnecessary boil water responses. More specific directions on these steps and when a boil water response may be necessary are provided in Department guidance and regulations.
A boil water response is NOT appropriate when chemical contamination is present. This may increase exposure to chemicals such as nitrates and solvents by concentration in the boiled water or by volatilization into the breathing zone. Boiling water is also NOT appropriate to address gross levels of contamination (e.g. raw sewage or high turbidity) when particulate matter can impair the effectiveness of boiling. Under these conditions, alternate water sources must be used.
WATERBORNE PATHOGENS
There are many disease causing organisms that consumers could be exposed to through ingestion and contact with contaminated drinking water. The more common pathogens that can be found in drinking water are as follows:
Protozoa: Protozoa are microorganisms that can live in animals, people and the environment. Many protozoa have life cycle stages that include cysts and oocysts. The cysts and oocysts are generally resistant to normal residual chlorine levels, but are more readily deactivated by ultraviolet (UV) disinfection. Most protozoa, including cyst and oocyst stages, will be removed by water filtration devices capable of removing 1 micron particles (i.e. microfiltration). In New York State, diseases caused by species of Giardia, Cryptosporidium, and amoebae must be reported to the NYSDOH.
Bacteria: Bacteria are usually killed by normal chlorine residual levels. Most bacteria will be removed by microfiltration (“<"1 micron) and most will be effectively deactivated by ultraviolet (UV) disinfection, although some species may require increased UV doses. Bacterial spores can be resistant to normal chlorine disinfectant levels and some are resistant to UV. Small bacteria and spores may pass through filters at the microfiltration level. Bacteria that can cause waterborne illness include Escherichia coli; and species of Salmonella, Vibrio, Shigella, and Camphylobacter. Viruses: Viruses are rapidly inactivated by normal chlorine residual levels. But their small size, typically less than 0.01 microns, allows viruses to pass through 1 micron filters. In addition, some viruses are resistant to inactivation by exposure to UV light. Hence, ordinary water filtration and UV disinfection may not provide adequate viral treatment and viruses are usually controlled with chemical disinfection. Viruses that can cause waterborne illnesses include: Hepatitis A,Adenoviruses, Hepatitis E, Enteroviruses (including Polio-, Echo and Coxsackie viruses), Rotaviruses, and Caliciviruses. BOILING AND PASTEURIZATION Boiling water kills or inactivates viruses, bacteria, protozoa and other pathogens by using heat to damage structural components and disrupt essential life processes (e.g. denature proteins). Boiling is not sterilization and is more accurately characterized as pasteurization. Sterilization kills all the organisms present, while pasteurization kills those organisms that can cause harm to humans. Cooking food is also a form of pasteurization. For pasteurization to be effective, water or food must be heated to at least the pasteurization temperature for the organisms of concern and held at that temperature for a prescribed interval. The effectiveness of pasteurization is directly related to temperature and time. Milk is commonly pasteurized at 149°F/65°C for 30 seconds, or 280°F/138°C for at least two seconds. A study of the effectiveness of pasteurization of milk intentionally contaminated with Cryptosporidium found that five seconds of heating at 161°F/72°C rendered the oocysts non-infectious. Although, some bacterial spores not typically associated with water borne disease are capable of surviving boiling conditions (e.g. clostridium and bacillus spores), research shows that water borne pathogens are inactivated or killed at temperatures below boiling (212°F or 100°C). In water, pasteurization is reported to begin at temperatures as low as 131°F/55°C for protozoan cysts. Similarly, it is reported that one minute of heating to 162°/72°C and two minutes of heating at 144°/62°C will render Cryptosporidium oocysts non-infectious. Other studies report that water pasteurized at 150°F/65°C for 20 minutes will kill or inactivate those organisms that can cause harm to humans. These include: Giardia, Cryptosporidium, Endameba, the eggs of worms, Vibrio cholera, Shigella, Salmonella bacteria, those that cause typhoid, the enterotoxogenic strains of E. coli, Hepatitis A and rotaviruses. It is also reported that a 99.999% kill of water borne microorganisms can be achieved at 149°F/65°C in five minutes of exposure. Water will boil at different temperatures under different conditions (e.g. lower temperatures at higher elevations, higher temperatures in pressure vessels), however these differences are not a significant factor for boil water responses. Water in an open vessel will boil at about 212°F/100°C in New York. Even on the top of Mt. Marcy, NY where the elevation is more than one mile above sea level, water boils at about 203°F/95°C and is adequate for disinfecting water. CHEMICAL DISINFECTION In cases where boiling water is not possible or practical and alternate water sources are not available, chemical disinfection may be a viable substitute. Chemical disinfection may be appropriate when boiling is not possible due to power outages, and is also an appropriate way to prepare water for non-ingestion uses such as washing dishes and personal hygiene. However, chemical disinfection by itself may not be as effective as boiling for pathogen control as some protozoans, such as Cryptosporidium in the cyst form, are resistant to both chlorine and iodine based disinfectants. Chemical disinfection should not be relied on to produce water for ingestion when gross levels of contamination or high levels of protozoans or turbidity may be present (e.g. raw sewage contamination). Under these conditions, alternate sources must be used for any water to be ingested or used in food preparation. Some chemical disinfectants are readily available as household chemicals (e.g. regular unscented chlorine bleach) or by purchase from pharmacies and outdoor stores (e.g. iodine tincture). Chemical disinfection can be accomplished on site by adding a specific amount of chemical to each gallon of questionable water and allowing the water to sit for a sufficient contact period before use. If the water is very cold, it should be warmed first or the contact time should be increased. To help reduce the taste and smell of chemical disinfectants, water can be aerated after the contact time is reached by pouring it back and forth between a pair of clean containers. Disinfection methods using ordinary household chemicals can be found at Disinfecting Tap Water. Disinfection with bleach should use regular, unscented bleach. Bleach that is scented, splash free or splash less should not be used due to additives in the bleach. Additionally, Clorox regular unscented bleach is certified in conformance with National Sanitation Foundation (NSF) Standard 60, which regulates the quality and purity of chemicals used for drinking water applications. WATER TREATMENT DEVICES Many water treatment devices are available for use in homes and commercial buildings, but few of them can be considered effective for pathogen removal. Many of these devices will have little or no effect on pathogens. An improperly maintained or ignored treatment device may actually add biological contamination to the water that passes through it. It is impractical to assess all of the treatment systems available, due to the sheer number available on the market and the proprietary nature of some of the processes. The following information is provided as a general overview for the public health professional. Point-of-use treatment units are manufactured and installed to treat water for use at a single location. Typical of point-of-use units are kitchen devices that treat only the water that comes out of the kitchen tap or water supplied to a nearby ice maker. There are also hand held treatment units such as water pitchers with a small integral filtration or carbon unit. Point-of-use devices installed in the kitchen will have no effect on potential exposures to water contaminants from bathroom sinks, showers, outside faucets, etc.. Often treatment systems are installed on part of a buildings plumbing, e.g. water softener on the hot water side, and these too are considered point-of-use. Specific types of treatment are discussed below. Point-of-entry treatment units are applied where water enters a home or commercial building and are installed to treat all of the water used at that location. Specific types of treatment are discussed below. Water Softeners & Ion Exchange Units - Water softeners and other ion exchange devices are not effective for removing pathogens and should never be used as a substitute for disinfection by boiling. Carbon Treatment Units - Carbon treatment provides effective removal of many chemicals, but is not effective for removing pathogens and should not be used as a substitute for disinfection by boiling. Improperly maintained carbon units in particular can actually increase the biological contamination in water that passes through it. Aerators - Aeration and oxidation units are often found in homes to treat water that has objectionable taste and odors, like sulfur compounds and chlorine, and to control nuisance minerals such as iron and manganese. Aerators are also used to remove radon. These provide no pathogen control and should never be used as a substitute for disinfection by boiling. Green Sand Filtration - Green sand units are chemical treatment devices designed to remove inorganic chemicals by oxidation. Though these units are called "filters" and have a sand media, they cannot be relied on to remove pathogens and should never be used as a substitute for disinfection by boiling. Physical / Mechanical Filtration - Physical filtration can be capable of effective pathogen removal and is used widely by water utilities for this purpose. Reverse osmosis is a form of filtration that uses specialized membranes and is addressed below. Many water filtration devices are marketed for home and commercial building use. Most of the available filter units use replaceable filter cartridges or bags, and some use membranes. The ability of a filter to remove pathogens is directly related to the size of the pores in the filter material, the quality of the unit, and the operation and maintenance of the unit. Filters rated for removal of particles that are one micron (a.k.a. micrometer, or 10-6 meter) or less in diameter are often referred to as microfilters. Filters of this size can remove the majority of water borne pathogens (protozoans and most bacteria), however, viruses are much smaller than one micron and may not be adequately removed by microfilter units. Public water systems that utilize cartridge filters in New York State, use cartridges that are rated for one micron absolute by a third party vendor and often utilize a chlorine disinfectant to inactivate viruses. The absolute rating means the filter removes 99.99% of the particulates for the rated size, and certification by a third party vendor (e.g. NSF, WQA or UL) to this level of performance increases the certainty of the performance, as well as the quality of the equipment and materials. Nominally rated cartridges, or other rating criteria provided by manufacturers vary from each manufacturer and often do not meet this standard. Reverse Osmosis - Reverse Osmosis (RO) is a form of filtration that works by forcing water under pressure through a specialized membrane. The pores in the membranes are sized so that water molecules pass though, but all particulates as well as larger molecules are removed. This type of filter is often rated by molecular size rather than by microns. A RO unit is capable of removing all waterborne pathogens and could be considered an acceptable substitute for disinfection by boiling if it is certified under ANSI/NSF standard 058 for "Cyst Removal", and it is under the control and operation of a certified water treatment plant operator or qualified nephrology technician (i.e. dialysis technician). However, because RO units are prone to fouling if turbidity levels are elevated, continuous operation during a boil water event may be difficult to accomplish without appropriate pretreatment. It should be noted that most RO units are also equipped with carbon pre-filters to protect the membranes from chlorine and large particulate. ADVANCE PREPARATION Advance preparation is key to effectively implementing a boil water response as a public health protection measure. To assist with this, the Bureau of Water Supply Protection has prepared a series of checklists and Frequently Asked Questions (FAQs) that address issues that arise when boil water events occur. These documents were prepared for different target audiences and should be used by public health staff to answer questions and as informational handouts for the public. Some water customers will have issues that are addressed in more than one of these FAQs (e.g. hospitals that are also food service establishments). Other advanced preparation items that can help both utilities and public health professionals ensure effective implementation of a boil water response include: Accurate identification and mapping of service areas Pre-identification of critical users (e.g. hospitals, schools, daycare centers, nursing homes/assisted living facilities, medical offices) Contact information for critical users (valid for off hours/24 hours a day) Contact information for public media (radio, newspaper, television) Water system emergency contacts (valid for off hours/24 hours a day) Up to date water supply emergency response plans Contact information for certified bulk haulers in the area ALTERNATE WATER SOURCES Boiling is the most reliable method the public can use to disinfect their drinking water and should be the first option for on-site disinfection. However, it may not always be possible or practical to boil water. Power outages may leave consumers unable to boil, and boiling may not be practical to meet some water needs. If needs are critical and cannot be discontinued, alternate water sources or other disinfection methods may be necessary. Generally, water used by the public for drinking and food preparation during a boil water event should be obtained in the following order of preference, depending on the scope of the affected area and incident specific conditions: Boiled (and then cooled) tap water Bottled water (certified for distribution in NY) Alternate public water supply (water from another public water supply that is not operating under a boil water notice) Bulk water arranged by a water utility or emergency agency Water chemically disinfected on-site Roadside springs are not a sure source of safe drinking water, since they are seldom monitored and no one is in charge of keeping them safe. Roadside spring water that is used for drinking or food preparation should be boiled (and then cooled) before use. Chemical disinfection is limited in effectiveness and is not appropriate for very turbid (muddy) water, or where raw sewage or other fecal matter may be present. In this case only use an alternate source of water. Chemical disinfection is discussed in greater detail in a previous section. RECOVERY When a boil water response has ended, recovery actions needed at consumer locations are often overlooked. Contaminated water may remain in plumbing lines, tanks, ice makers, and other equipment and can sicken consumers. Information should be provided to consumers to inform them of the need to flush and/or disinfect pipes, tanks and equipment. No single set of recommendations for flushing or disinfection can apply to all users, however, checklists and fact sheets are available from the Department to help consumers implement the final protective steps needed to assure the return to potable water.

What Temperature Kills Bacteria in Water and Food?
Share on Pinterest Bacteria are microscopic, single-celled organisms. They’re found all over the world and in many different environments — even within your body. In fact, it’s estimated that we have 10 times more bacterial cells in our body than human cells. While most bacteria don’t cause illness in humans, there are some that do. These are called pathogenic bacteria. A few examples include: the Salmonella species
E. coli
methicillin-resistant Staphylococcus aureus (MRSA) You can lower your risk of becoming sick by taking steps to reduce your exposure to these types of bacteria. In fact, there are different ways to kill pathogenic bacteria in water, in food, or on a household surface. Let’s take a closer look at what temperatures can kill bacteria, as well as other steps you can take to get rid of potentially harmful bacteria in your home.
What temperature kills bacteria in water? Several types of disease-causing organisms can be present in water, including bacteria. Some examples of bacterial illnesses that you can get from contaminated water include: salmonellosis
shigellosis
gastroenteritis caused by E.coli as well as some Vibrio species
dysentery
typhoid fever
cholera Due to modern water treatment methods, this isn’t something that we often worry about. However, there are some circumstances in which bacteria can be present in water. These include scenarios where: regular water service has been interrupted, due to a water line break or a natural disaster
you’re traveling and are unsure of the quality or safety of the water
water has been unsafely treated, handled, or stored The World Health Organization (WHO) notes that bacteria are rapidly killed at temperatures above 149°F (65°C). This temperature is below that of boiling water or even a simmer. In order to be sure that you’ve killed pathogenic bacteria that may be present in water, the Centers for Disease Control and Prevention (CDC) recommends the following: If the water is cloudy, either let it settle or filter it through a coffee filter or clean piece of cloth before you boil it. Bring the water to a rolling boil. This is the point where the water is boiling very vigorously with lots of bubbles. Allow the water to boil like this for at least 1 minute. Remove the water from the heat source and allow it to cool down. Once the water has cooled, store it in a clean, tightly-secured container. Additional tips for killing bacteria in water If you don’t have ready access to a heat source, there are other things that you can do to kill bacteria in water. For example, you can use household bleach to disinfect water by following these steps: Select a regular, unscented chlorine bleach that’s less than 1 year old. Check the label to verify that it’s suitable for disinfection or sanitization and that the active ingredient is sodium hypochlorite. If the water is cloudy, allow it to settle or filter it using a coffee filter or clean cloth. Using a clean eyedropper, add an appropriate amount of bleach to the water. The Environmental Protection Agency (EPA) has a chart of how much to add based off of the volume of water and the concentration of your household bleach. Stir the water and allow it to sit for at least 30 minutes. Water disinfection tablets are also commercially available. If you choose to use these, be sure to carefully follow the instructions provided on the product label.
What temperature kills bacteria in food? Some types of bacteria can be a potential cause of food poisoning. It’s estimated that 1 in 6 Americans becomes ill with food poisoning every year. Some common foods associated with bacterial food poisoning include: raw or undercooked poultry (Salmonella, Campylobacter)
raw or undercooked meats (E. coli, Salmonella)
raw or undercooked seafood and shellfish (Vibrio, Salmonella, Shigella)
fresh produce (E. coli, Salmonella, Listeria)
eggs (Salmonella)
unpasteurized dairy products (Salmonella, E. coli, Campylobacter, Listeria) There are several different ways that you can be exposed to pathogenic bacteria in or on foods. Some examples include: eating meat, poultry, or fish that’s raw or undercooked
consuming fresh produce that hasn’t been washed
eating dairy products that haven’t been pasteurized
allowing perishable foods to sit out at room temperature for too long
not washing your hands before you handle or prepare food
cross-contamination, where bacteria from one food is transferred to another Pathogenic bacteria grow quickly in food at temperatures between 40 to 140°F (5 to 60°C) . In order to kill these bacteria, it’s important to cook all foods to a safe internal temperature. The CDC lists the following temperature guidelines for several common types of food: poultry, whole or ground: 165°F (74°C)
165°F (74°C) whole cuts of meat (beef, pork, lamb, or veal): 145°F (64°C)
145°F (64°C) ground meats: 160°F (71°C)
160°F (71°C) fresh ham: 145°F (64°C)
145°F (64°C) fish: 145°F (64°C) or until meat is opaque
145°F (64°C) or until meat is opaque leftovers or casseroles: 165°F (74°C) Additional food safety tips In addition to making sure that food is cooked to the proper temperature, the following strategies can also help reduce your risk of food poisoning: Wash your hands. Be sure to wash your hands before and after preparing food, before eating, and after handling raw meats.
Be sure to wash your hands before and after preparing food, before eating, and after handling raw meats. Separate. Keep raw meats or eggs separated from other foods to prevent cross-contamination. This includes storing them away from other foods in the refrigerator, and using a separate cutting board during food preparation.

Be sure to thoroughly rinse any fresh produce before eating it or using the produce in a recipe. Thaw safely: Be sure to thaw foods in the refrigerator or in the microwave. Thawing food on the countertop can promote the growth of bacteria. Did you know? Some bacteria can survive at very high temperatures. These types of bacteria are called thermopiles, which means “heat loving.” Thermophiles are harmless to humans and grow best at temperatures between 113 to 176°F (45 to 80°C). They’re often found in hot springs and in hydrothermal vents deep in the ocean.
What else can help kill bacteria in your home? In addition to using heat, there are a variety of other steps you can take to get rid of harmful bacteria in your home. Killing bacteria on surfaces Many surfaces in your home can also harbor pathogenic bacteria. This is particularly true of surfaces that you touch often. Although using normal cleaning products can help reduce bacteria on household surfaces, disinfectants can kill them. Some examples of disinfectants that can kill bacteria on surfaces include: products that contain alcohol, such as ethanol and isopropyl alcohol
household bleach
products that contain ammonium compounds In order to disinfect surfaces in your home, follow the tips below: Follow the product instructions. Each product will come with its own specific set of instructions, including how much to use, ideal contact time, and the appropriate surfaces to use the product on.

Follow the manufacturer’s instructions when cleaning surfaces like phone screens or TV screens. If no instructions are available, use an alcohol-based wipe or spray. In addition to using disinfectants, opening your blinds may also reduce bacteria on household surfaces. A 2018 study found that sunlight exposure can reduce some types of bacteria found in household dust. Killing bacteria on fabrics It’s also possible for bacteria to be present on fabrics, such as clothes, towels, and bed linens. Generally speaking, washing and drying these fabrics as you normally would can help reduce or eliminate bacteria on these items. However, some items are at a higher risk for spreading illness. Some examples include: healthcare workers’ uniforms
towels or cloths used while preparing food
shared bath towels
clothes worn while playing sports
fabrics that have been in contact with an open wound or have been soiled with vomit or feces To wash high-risk fabrics, do the following: Clean these fabrics separately from your normal laundry. Always wash your hands after handling them. For the wash cycle, use hot water —140°F (60°C) — and a bleach-based laundry product. After the wash cycle, promptly tumble dry the fabrics. A 2014 study found that tumble drying after a high temperature wash was important for reducing bacteria on laundry.
What about viruses? Viruses are tiny microbes that are even smaller than bacteria. On the most basic level, they’re made up of RNA or DNA that’s enclosed in a protein shell. Some viruses may also be surrounded by a membrane called an envelope. Viruses are parasites. They need to invade a host cell in order to replicate. Like bacteria, they can cause disease in humans. Some examples of viral illnesses that you may be familiar with include: the common cold
the flu
COVID-19
measles
HIV infection
viral hepatitis Generally speaking, many viruses are sensitive to environmental factors like temperature and humidity. Some only survive outside of the human body for a matter of hours or days, although others can remain viable for weeks. You can eliminate viruses from your home in much the same way as bacteria or other germs. This includes: disinfecting household surfaces
boiling water if necessary
cooking foods to the proper temperature
