How to Tell if Canned Tuna is Bad
Canned tuna is a staple in many households, but it’s important to know how to tell if it’s gone bad. Eating spoiled tuna can cause foodborne illness, so it’s crucial to be able to identify the signs of spoilage.
In this article, we’ll discuss the different ways to tell if canned tuna has gone bad, including physical signs, smell, and taste. We’ll also provide tips on how to store canned tuna properly to extend its shelf life.
Physical Signs of Spoiled Canned Tuna
One of the most obvious signs that canned tuna has gone bad is if the can is bulging or leaking. This is a sign that bacteria have begun to grow inside the can, and the tuna is no longer safe to eat.
Another physical sign of spoilage is if the tuna has changed color. Fresh tuna is typically a light pink or red color. If the tuna has turned brown or gray, it’s likely that it has gone bad.
Smell of Spoiled Canned Tuna
Another way to tell if canned tuna has gone bad is by its smell. Fresh tuna has a mild, fishy smell. If the tuna has a strong, unpleasant odor, it’s likely that it has gone bad.
Some people describe the smell of spoiled canned tuna as being similar to ammonia or sulfur. If you notice a strong, unpleasant odor coming from your canned tuna, it’s best to throw it out.
Taste of Spoiled Canned Tuna
If you’re still not sure whether or not your canned tuna has gone bad, you can try tasting it. Fresh tuna has a mild, delicate flavor. If the tuna tastes sour, bitter, or metallic, it’s likely that it has gone bad.
It’s important to note that canned tuna can sometimes have a slightly sour taste due to the canning process. However, if the sour taste is strong or accompanied by other signs of spoilage, it’s best to throw the tuna out.
