Due to its antibacterial properties salt has long been used as a preservative. Salt kills some types of bacteria, effectively by sucking water out of them. In a process known as osmosis, water passes out of a bacterium so as to balance salt concentrations on each side of its cell membrane.
Next I liberally salt it and let sit 15 to 30 minutes at room temperature: this will draw moisture from the surface as well as kill any surface bacteria that would otherwise contribute to bad odor and/or flavors during cooking.
Does salt water kill bacteria? Salt water may kill some, but does not kill all, mouth and throat bacteria. However, solutions of salt can help bring bacteria to the surface of the gums, teeth, and throat. Once the bacteria is brought to the surface, some of it washes away when a person spits the salt water out.
Sea salt is a natural antiseptic and anti inflammatory that for thousands of years has been used in wound cleansing. Remember the expression, “throwing salt on a wound?” That's because that's what people actually did to clean out infected cuts, and scraps.
Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.
Common salt reduces the number of certain lactic acid bacteria in the gut of humans. This has an impact on immune cells which are partly responsible for autoimmune diseases and hypertension.

Boil. If you don't have safe bottled water, you should boil your water to make it safe to drink. Boiling is the surest method to kill disease-causing germs, including viruses, bacteria, and parasites. adding a pinch of salt for each quart or liter of boiled water.
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 can be used as a pathogen reduction method that should kill all pathogens. Water should be brought to a rolling boil for 1 minute. At altitudes greater than 6,500 feet (approximately 2,000 meters), you should boil water for 3 minutes.
Common household iodine (or “tincture of iodine”).
You may have iodine in your medicine cabinet or first aid kit. Add five drops of 2% tincture of iodine to each quart or liter of water that you are disinfecting. If the water is cloudy or colored, add 10 drops of iodine.
Salt inhibits the growth of microorganisms by drawing water out of microbial cells through osmosis. Concentrations of salt up to 20% are required to kill most species of unwanted bacteria.
Most of these bacteria are Proteobacteria, a group of bacteria that are commonly found in the oceans. All of these sea salt bacteria Ben isolated are halophilic, meaning they love and can tolerate high concentrations of salt.
NPR's Salt blog explains: Pierce and his colleagues discovered that by adding a little table salt to this murky water, they could get the particles of clay to stick together and settle to the bottom, making the water clear enough to purify using the solar disinfection method.
Salt and pH
A study published in the 2011 issue of the "Journal of Food Sciences" compared 10 commercial brines for their ability to control E. coli growth on cucumbers and found that those with the lowest pH and those with the highest salt concentrations were the quickest to kill pathogenic bacteria.
Saline solutions made with table salt can provide some superficial cleaning benefits, but it isn't a powerful infection fighter. By contrast, you can expose the same cut or scrape to a warm Epsom salt soak to reduce pain and fight back against the invading bacteria.
Halophiles are organisms represented by archaea, bacteria, and eukarya for which the main characteristic is their salinity requirement, halophilic “salt-loving”. Halophilic microorganisms constitute the natural microbial communities of hypersaline ecosystems, which are widely distributed around the world [1].
If bacteria are exposed to very high salt or sugar concentration, they will lose water and their cell contents will become plasmolyzed, resulting in their death.
They found that the bacteria employs a survival strategy by sequestering sodium or potassium ions so as to maintain the ionic concentration inside the cell equivalent to or higher than the external environment.
Dry-salting fish, or curing them in a saturated salt brine, for 5-7 days before pickling will kill nematodes and tapeworms. Pickling without salt curing may not destroy some nematodes.
Epsom salt has the ability to draw out toxins, dirt and bacteria from the body, even those hiding in the corner of your nails. So, yes, it does kill bacteria and thereby keeps infections at bay.
No, vinegar does not disinfect or sanitize.
Vinegar is not an EPA registered disinfectant, which means it has not been tested, proven and certified by the federal EPA to kill 99.9% of a sufficient range of bacteria and viruses.
Hooton says although it's simplistic, drinking a lot of water helps flush out the bacteria that can cause an infection.
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.
Clean with water, soap, and scrubbing. Sanitizing reduces germs to levels public health codes or regulations consider safe. Sanitizing is done with weaker bleach solutions or sanitizing sprays. Clean surfaces before you sanitize them.
