When noodles have gone bad the noodles will feel sticky or slimy and also smell or be stale.
If the noodles have any dark or fuzzy spots or mold then the noodles are spoiled and should be thrown out.
Another sign of noodles having gone bad are discoloration or dullness like a white color or gray color.
Dry uncooked noodles when stored properly last around 1 year to 2 years and sometimes longer.
Cooked noodles last for around 3 to 5 days in the refrigerator.
If you want to keep cooked noodles longer than 3 to 5 days you can freeze them and they will last for 6 month to a year.
If you believe the noodles have gone bad or they taste off or have a bad smell to them you should throw them out to avoid risk of food poisoning.
The bacteria that you can get from spoiled noodles is Baccilus cereus which is a common bacterium found all over the environment.
It begins to cause problems if it gets into certain foods that are cooked and not stored properly.
Starchy foods like rice and pasta are often the culprits.
But it can also affect other foods, like cooked vegetables and meat dishes.
