** The important thing with spaghetti sauce is that the jar lid must not be "popped" or raised prior to opening. If your lid is raised, return it to the store for a refund.
Remember, once spaghetti sauce is opened - whether it came from a jar, a can, a package, or homemade spaghetti sauce it should be kept stored in the refrigerator and used within within 5-10 Days depending on the brand of sauce. Most pasta sauces do NOT have any preservatives. Therefore, be sure to cook your sauce if it has been opened and stored in the fridge for longer than 4-5 days - but toss the sauce for sure if it has been more than 9-10 days or if you see any signs of mold formation.

Practicing proper hygiene and food safety techniques will help prevent foodborne illness.
Spaghetti Sauce will begin to darken from a bright red to a maroon color and will get thicker over time. After the eat by date has passed, the spaghetti sauce will begin to form mold, even in the refrigerator. If there is any visible mold (mould) at all, the entire jar should be thrown away - even if it is just on the lid of the jar!
There are, of course, certain health risks associated with spoiled foods so always remember to practice food safety and enjoy your foods before their shelf life has expired!

I've spent years diving into the intricacies of food safety, specifically focusing on sauces, including the beloved spaghetti sauce. Trust me; I've got a well-stocked arsenal of information on this. Let's start with the idea that the lid of your spaghetti sauce jar should remain firmly in place until you decide to open it. The reason? Preserving freshness. If that lid is popped or raised prematurely, you might want to reconsider your purchase.
Once opened, the clock starts ticking, my friend. Whether it's from a jar, can, package, or crafted in your kitchen, spaghetti sauce has a limited stay in the fridge—typically 5-10 days, depending on the brand. And here's a nugget of wisdom: most pasta sauces skip the preservatives, so if your sauce has been lounging in the fridge for more than 4-5 days, it's cooking time. But if it's been more than 9-10 days or you spot mold, bid your sauce farewell.
Now, the manufacturers have their say. Newman's Own gives you a 3-7 day window, Ragu's cheese-based sauce lasts 3 days, and their tomato-based version is good for 3-5 days. Barilla and Classico are in the same ballpark, suggesting 3-5 days for opened sauce in the fridge. Freeze it? Barilla says 3 months, Classico extends to 2-3 months. Oh, and please check the table—they might be generous or cautious depending on factors like your fridge's temperature, time spent outside the cold embrace, and the risk of cross-contamination.
And let's not forget the signs of an aging sauce—darkening, thickening, and heaven forbid, mold. If you see mold, toss the entire jar. No compromise.
Storing it right is key, my friend. Sealed containers in the fridge or freezer can be your allies in the fight against spoilage. Benefits? Sure, fresher sauce, lower food costs, and a nod to the environment by avoiding waste.
Now, did you know a quarter cup of tomato-based sauce is about 70 calories and 3g of fat? Alfredo sauce packs 110 calories and 10g of fat, while pesto saucily flaunts 290 calories with 29g of fat in the same serving size.
So, when it comes to spaghetti sauce, knowledge is your shield against the perils of a poorly handled jar. And remember, my friend, enjoy it before its shelf life waves its final goodbye!
