What happens if you eat expired tomato sauce?

In this short article, we will provide an answer to the question “what happens if you eat expired tomato sauce?” and the ways to store the tomato sauce properly, and the ways to detect spoilage of tomato sauce.


What happens if you eat expired tomato sauce?


If you eat expired tomato sauce, you may become ill. When taken in high quantities, toxic tomato sauce can cause food poisoning and possibly Botulism. Botulism is a foodborne illness that can be caused by improper canning or storage of tomato sauce. It is a moderately common foodborne illness.


18-36 hours after ingesting poor tomato sauce, symptoms begin to manifest themselves. The most common symptoms include nausea, diarrhea, vomiting, and stomach pains, to name a few.


It is also possible to encounter symptoms such as impaired speech and breathing issues, as well as difficulties swallowing and muscle weakness. Botulism is a serious illness that can be fatal if left untreated.


What is the shelf life of tomato sauce?


When compared to many other sauces, tomato sauce has a much longer shelf life before turning bad. Given the lack of preservatives in commercial sauces that are intended to be a complete meal, it is generally accepted that they should be discarded after seven days. 


Type Pantry (Unopened) Refrigerator (Opened) Freezer (Opened)
Can or Glass Jar Up to 2 Years 5-7 Days Up to 18 Months
Homemade (Properly Canned) Up to 1 year 3-4 Days 4-6 Months


The shelf life of tomato sauce is approximately one year.


It is possible to store unopened tomato sauce in your cabinet for approximately 2 years if it is stored in a can or jar that has been properly maintained. Once opened, store in the refrigerator for up to a week or freeze for up to 18 months in a freezer-safe container to keep the flavor from deteriorating. Tomato sauce typically lasts much longer than the date on the container that indicates when it should be used.


Can Tomato Sauce be kept out of the fridge for an extended time?


When the tomato sauce is withdrawn from the refrigerator, it loses its shelf life quite rapidly. After a few weeks, the color will begin to change as a result of exposure to heat and temperature differences in the environment. Keep in mind that once you’ve opened the Tomato Sauce, it won’t last more than a few days if left at room temperature, so plan accordingly.


How Long Does Refrigerated Tomato Sauce Last?


Sauces should be kept in the refrigerator for up to a week after being opened in warm climates, but they should be kept out of the freezer. Even throughout the winter, putting them in a root cellar or refrigerator will help to extend their shelf life significantly. Tomato sauce has a three-year shelf life provided it is kept refrigerated.


Is it OK to consume tomato sauce that has passed its expiration date?


Tomato sauce that has not been produced from scratch beyond its expiration date should be fine in the refrigerator for another three months or so. If the color hasn’t changed, you can keep it in the fridge for a little while longer if necessary.


It is possible to detect ketchup spoiling by examining for the following characteristics: 


  • Rancidity, flavor, and color are the three main parameters to detect the spoilage of the tomato sauce.


  • After some time, the watery portion of a beverage will separate from the thicker portion; the beverage is still safe to consume, but the flavor will be degraded sooner or later.


  • Because of the separation of the liquid, ketchup thickens and darkens in color, losing its bright crimson tint and taking on a darker maroon hue instead. Food that has changed color from its original condition has most certainly been around for a lengthy time, and it has likely impacted the flavor at the very least.


  • Food safety should be practiced consistently, and commodities should be used before their shelf life has expired, as there are some health risks linked with spoiled meals!


What is the most effective technique to keep leftover tomato paste fresh?


Any remaining tomato paste should be kept in the refrigerator. Making use of the smallest container possible will help to lower the amount of air in the container overall (even a zip-top bag). For safety reasons, never store it in the tin container for extended periods.
