As the weather gets colder, there’s nothing like a big bowl of piping hot soup to warm up your body and soul. However, have you ever wondered how long that soup would last before it becomes unsafe to eat? When it comes to storing perishable food items, like soup, it’s crucial to know how long they can sit out of the fridge before it becomes a breeding ground for bacteria and other harmful substances.
When it comes to soup, it’s common to leave a pot simmering on the stove throughout the day, with everyone dipping in and out as they please. However, leaving it out for extended periods can be a recipe for disaster. So how long does soup last out of the fridge? The answer may surprise you. The general rule of thumb for cooked soup that has been left out is about two hours. After that time, it’s recommended that you throw it out. However, this timeline can be even shorter depending on various factors, like the type of soup and the surrounding temperature.
If you’re like most people, you may see nothing wrong with reheating soup that’s been left out overnight. But did you know that it can be a breeding ground for bacteria like botulism that can be life-threatening? Keeping a close eye on food safety when it comes to food storage is essential, even with something as simple as soup. Now that we know how long soup lasts out of the fridge, it’s essential to take the necessary precautions to keep everyone in your household safe from foodborne illnesses.
Shelf life of soup at room temperature
Many people wonder how long they can leave soup out at room temperature without risking food poisoning. The answer is not straightforward because it depends on various factors such as the ingredients used, the cooking method, and the storage conditions. Generally, soup should not be left out at room temperature for more than two hours. Bacteria that cause foodborne illnesses can grow rapidly at temperatures between 40°F and 140°F, also known as the “danger zone.”
- If the soup contains meat, fish, or dairy products, it should be refrigerated within one hour of cooking and should not be left out at room temperature for more than one hour.
- If the soup is vegetarian or vegan, it can be left out at room temperature for up to two hours.
- If the soup is thick and has a pH level of 4.6 or lower, it can be left out at room temperature for up to four hours.
It’s worth noting that even if the soup does not show any signs of spoilage, such as an off-smell or appearance, it may still contain harmful bacteria. Therefore, it’s essential to follow safe food handling practices and discard any soup that has been left out at room temperature for too long.
Factors affecting the shelf life of soup at room temperature
When it comes to storing soup, the temperature is crucial in determining how long it will remain safe to consume. Room temperature is not ideal for soup as it provides the perfect breeding ground for bacteria to thrive. Several factors come into play when it comes to determining how long soup can last at room temperature:
- The type of ingredients used: Some ingredients in the soup can quickly spoil and cause the soup to go bad even when stored in the refrigerator. For example, milk-based soups will go bad faster than vegetable-based soups.
- The acidity level of the soup: Soups with a higher level of acidity will last longer than those with lower acidity levels since acid inhibits bacterial growth.
- The storage conditions: Storage conditions play a significant role in determining how fast the soup will spoil. If the soup has been stored under questionable circumstances, it will go bad faster than if it was correctly stored in the first place.
It is essential to note that soup left out for extended periods can cause food poisoning or gastroenteritis. Bacteria that cause these illnesses can multiply in the soup once the temperature goes above 4 C (40 F). It can lead to symptoms such as diarrhea, abdominal cramps, and nausea within hours of consuming the soup.
Signs that your soup has gone bad
You can tell when your soup has gone bad by looking out for specific signs. Here are some of the common signs that your soup has gone bad:
- A sour or off smell: Soup with a sour smell or an off taste indicates that it has gone bad and should be discarded immediately.
- A change in color or texture: Soup that has changed color or appears slimy or moldy is not safe to consume. Mold poses health risks when consumed and should be avoided at all costs.
- Bubbles and a fizzy or gassy taste: The presence of bubbles or a fizzy taste in your soup is a clear indication that bacteria are present and have started to multiply.
How to store soup properly at room temperature
The best way to ensure that soup stays safe for consumption is to store it in the refrigerator or freezer immediately after cooking.

Common types of spoilage bacteria found in soups
Food spoilage is the process of food becoming unsafe or undesirable for human consumption. Soups, in particular, are prone to spoilage due to the abundance of nutrients they contain. Here are some common types of spoilage bacteria found in soups:
- Clostridium perfringens – This anaerobic bacteria is commonly found in soil and human and animal intestines. It can cause foodborne illness if soup is not properly stored or reheated.
- Bacillus cereus – This aerobic bacteria is found in soil, dust, and some processed foods. It causes food poisoning with symptoms like diarrhea and vomiting.
- Lactic acid bacteria – They normally play a role in fermented foods, but in spoiling soups, they produce slimy, sour, and off-flavor soup. They are mostly found in cream-based soups.
- Listeria monocytogenes – This aerobic bacteria is commonly found in soil, water, and animal waste. It causes a severe disease called listeriosis, which is a risk for pregnant women, older adults, and people with compromised immune systems.
- Salmonella – This aerobic bacteria is commonly found in raw meat, poultry, and eggs. It causes food poisoning with symptoms like diarrhea, fever, and abdominal pain.
- Escherichia coli (E.coli) – This bacteria is commonly found in the intestines of warm-blooded animals, including humans. It causes food poisoning with symptoms like diarrhea, abdominal pain, and vomiting.
It’s important to note that not all bacteria are harmful, but some bacteria can cause serious health problems. The secret to preventing spoilage bacteria from ruining your soup is to practice good hygiene, temperature control, and proper food storage.
The impact of high altitude on soup shelf life.
Did you know that the shelf life of soup can be affected by the altitude at which it is stored? Here are some things to keep in mind:
- At higher altitudes, the air pressure is lower, which can cause food to cook at a lower temperature and water to boil at a lower temperature. This can affect the cooking time of soup and can also make it harder to properly cook raw ingredients like meat and vegetables.
- Furthermore, lower air pressure can lead to increased evaporation in soup. This not only dries out the soup, but it also increases its concentration of bacteria and other microorganisms.
- In higher altitudes, the lower atmospheric pressure makes the boiling point of water lower too. For example, in cities above 300 meters above sea level, water boils at a lower temperature that 100 degrees Celsius.
If you live in a high altitude area, it’s important to take extra precautions when it comes to storing food, including soup. Keep in mind that hot food should be cooled down properly before it is stored, and that it should be refrigerated as soon as possible.
Here’s a helpful table that shows the recommended maximum storage times for different types of soup at different altitudes:
| Altitude | Recommended maximum storage time for soup |
|---|---|
| 0-1000 ft (0-305m) | 3-4 days |
| 1000-3000 ft (305-915m) | 2-3 days |
| 3000-6000 ft (915-1830m) | 1-2 days |
| Above 6000 ft (above 1830m) | Less than 24 hours |
As you can see, the higher the altitude, the shorter the recommended storage time for soup. This is because the reduced air pressure and increased evaporation can cause soup to spoil more quickly.
In summary, if you live in a high altitude area, it’s important to take extra precautions when it comes to storing soup. Be sure to cool it down properly and refrigerate it as soon as possible, and keep in mind the recommended storage times based on your altitude.
