No, you do not need to refrigerate soy sauce. While it is often suggested to store packaged soy sauce at room temperature, you can store it in the refrigerator if desired. It may help extend the shelf life of the sauce, but it will be safe to consume at room temperature even if it is opened and left unrefrigerated.
The safety of soy sauce will not be compromised if stored at room temperature, however, it can and will go bad eventually. The shelf-life of unopened bottles of soy sauce is 1-2 years if stored in a cool, dry place, while opened bottles of soy sauce have a shelf-life of about 1 month if stored in a cool, dry place.
Refrigeration can increase the shelf-life of opened bottles of soy sauce up to 6 months. Therefore, it is up to the personal preference of the individual as to whether or not to refrigerate soy sauce.
What happens if you don’t refrigerate soy sauce?
If you do not refrigerate soy sauce, it will still be edible, however, its shelf-life and flavor can become compromised. If it is left at room temperature, the flavor of the soy sauce will become more intense and it can potentially develop off-flavors.
Additionally, soy sauce can become cloudier and expire faster due to the presence of bacteria, enzymes, and other naturally-occurring microorganisms. To get the best out of soy sauce, it is recommended to refrigerate it and discard it after about 1 year of being opened.
Because it is highly concentrated, the flavor remains for much longer if you keep it cold.
Can soy sauce go bad if not refrigerated?
Yes, soy sauce can go bad if it is not refrigerated. As soy sauce is a fermented product made with soybeans, wheat, salt, and water, if it is left at room temperature, it can quickly spoil and become unsafe to eat.
Spoiled soy sauce will have an unusual smell and taste and may contain harmful bacteria, such as E. coli. To avoid this, soy sauce should be kept in cool, dry conditions, such as the refrigerator. It should also be kept in a sealed container with an airtight lid, as soy sauce can absorb flavors and odors from other foods.
Unopened soy sauce can last for several years if stored properly and can be used up to 6 months after opening.
How do you know if soy sauce is bad?
If you’re wondering if soy sauce has gone bad, there are a few signs you can look for. For starters, check the expiration date on the bottle. If it expired, then the soy sauce must no longer be used.
You can also smell the soy sauce, as any noticeable changes in smell could mean it’s no longer safe to consume. Additionally, any signs of off-putting discoloring or an unusual texture could mean your sauce is no longer edible.
You can also pay close attention to the taste; if it’s too salty or not salty enough, it’s probably best to discard the sauce. Lastly, check the container: if it’s bloated, it’s safe to assume the soy sauce has gone bad.
Can bacteria survive in soy sauce?
Yes, bacteria can survive in soy sauce. Soy sauce is a fermented food product made from soybeans, wheat, and other ingredients. The fermentation process and high salt content can create an environment that is suited for the growth and survival of various types of bacteria.
Common bacteria that can survive in soy sauce include Salmonella, Listeria, E. coli, and Vibrio cholerae. Although the conditions in soy sauce are not ideal for bacterial growth, bacteria can form a biofilm that protects them and allows them to survive.
In addition, improper storage and handling of soy sauce can cause anaerobic bacteria to form colonies that can survive in the sauce and cause spoilage. If a jar of soy sauce has an unpleasant odor, is discolored, or has an off-flavor, then it is likely spoiled and should be discarded.
To prevent bacterial growth and spoilage in soy sauce, it is important to store it in a cool, dry place, and always ensure that it is refrigerated after opening.

Over time, bacteria and other microorganisms can contaminate the sauce, which can lead to food poisoning. Additionally, if the bottle has been opened and exposed to air, the shelf-life of the soy sauce may be drastically reduced.
It is always best to be extra cautious when consuming sauces and food that have passed their expiration dates, to avoid any potential health risks.
Does sealed soy sauce go bad?
Generally speaking, sealed soy sauce should not go bad if it is stored properly. When unopened and stored in a cool, dark place, soy sauce can last up to two years before it starts to break down and lose its flavor.
Once opened, soy sauce will last between 6-12 months before it starts to deteriorate. It should also be noted that once opened, the flavor of the soy sauce may start to slowly deteriorate even if the sauce doesn’t go bad.
Because of this it is best to consume the opened soy sauce within 6 months to ensure optimal flavor. Additionally, it is recommended to always check the expiration dates on individual soy sauce bottles to ensure that the sauce does not go bad before it is used.
Servers should also be sure to store the opened soy sauce in an airtight container away from light and heat to prolong the life of the sauce.
Is it OK to use soy sauce that wasn’t refrigerated?
It is usually okay to use soy sauce that hasn’t been refrigerated, as long as it is unopened. Soy sauce is a fermented product, which means it has a higher acid level than non-fermented products and is more shelf-stable.
In fact, some manufacturers don’t suggest storing soy sauce in the refrigerator because it can affect the flavor.
However, if the soy sauce has been opened and is exposed to air, bacteria can grow. Therefore, you should discard opened soy sauce if it has been left at room temperature for a long period of time. If you are unsure how long it has been exposed to the air, it is better to be safe and throw it away.
Can you get food poisoning from soy products?
Yes, it is possible to get food poisoning from soy products. When soy products are handled and prepared improperly, they can become contaminated with bacteria such as E. coli and Salmonella. These bacteria can then lead to food-borne illnesses such as stomach cramps, vomiting, and diarrhea.
To reduce the risk of food poisoning from soy products, it is important to store and handle them properly. This includes storing them at temperatures below 4ºC, keeping them away from raw meat and eggs, and washing any cutting boards or countertops after handling them.
When cooking soy products, they should be heated to the appropriate temperature of at least 74ºC to kill off any potential bacteria. Finally, any leftovers should be refrigerated quickly and consumed within two days.
Can you get Salmonella from soy?
No, you typically cannot get Salmonella from soy. Soy is a legume, and Salmonella is a bacteria that typically lives in the intestines of warm-blooded animals, meaning it is not typically found in legumes.
Although it is theoretically possible to get Salmonella from soy, it is very unlikely, as legumes are not a common host for Salmonella. Also, since most soy products are cooked prior to consumption, it makes it even more difficult for Salmonella to survive.
The only way to really get Salmonella from soy would be to consume it raw, which is not recommended. It is much more likely to get Salmonella from eating undercooked poultry and eggs, which are known to be common carriers for Salmonella.
All in all, it is highly unlikely that you can get Salmonella from soy.
Can you preserve things in soy sauce?
Yes, you can preserve things in soy sauce. This is known as zha cai, which is a type of pickled vegetable that is made by marinating the vegetable in a salty soy-based sauce. The salty soy sauce will not only give the vegetables a unique flavor, but it will also help to preserve it and keep it from going bad.
To make zha cai, you simply need to mix together soy sauce, garlic, peppers, ginger, and other spices. The vegetables are then left to marinate for a few days, or up to a month, depending on the desired taste.
This type of pickling is a great way to preserve vegetables and enjoy them months later.
Can you get sick from old soy sauce?
Yes, you can absolutely get sick from old soy sauce, and it is important to be aware of its shelf life. Like any other food, soy sauce can spoil and cause health issues, such as food poisoning, if it is not stored properly.
Soy sauce is classified as a condiment and usually has a shelf life of one to two years. Signs of spoilage include a strange odor and a change in color, texture, and taste. Additionally, mold or a thin layer of oil on the surface of the sauce is an indication that it has gone bad and should be thrown out.
It is important to follow the expiration date stamped on the bottle, and store it in a cool and dry area away from heat and sunlight. If you have an open bottle of soy sauce, you must keep it refrigerated to maximize its shelf life and quality.
Is soy sauce OK after food poisoning?
I would not recommend eating soy sauce or any other food or drink after experiencing food poisoning. Food poisoning is best treated by rest and hydrating with plenty of water and/or electrolyte beverages.
Additionally, foods such as bland starchy foods (such as toast and plain potatoes) may help to calm the stomach. Avoiding overly spicy, acidic, and greasy foods may also help to prevent any further irritation to the stomach.
If the symptoms of food poisoning persist for more than a day or two, it may be best to see a doctor for further advice.
