What Happens if You Eat Expired Tuna?
Eating expired tuna can lead to food poisoning.
Expired canned tuna may have a deteriorated quality and compromised texture and taste.
If the seal of the can is compromised, the tuna can be exposed to bacteria and other contaminants.
Food poisoning from tuna can result in symptoms such as nausea, vomiting, and liver failure.
It is best to discard expired tuna to avoid potential illnesses.
Quick Tips and Facts:
1. Eating expired tuna can potentially lead to a condition known as scombroid poisoning, which mimics symptoms of food poisoning but is actually caused by the buildup of histamine in the fish.
2. The “sell-by” date on canned tuna refers to the date until which the store should sell the product, but it does not necessarily indicate the expiration date. Canned tuna can remain safe to eat for years after this date if stored properly.
3. Tuna caught using the traditional pole-and-line method is generally fresher and less likely to spoil quickly than tuna caught using large fishing nets. This is because individual fish are caught and iced immediately, minimizing the risk of bacterial growth.
4. Ancient Romans used a preparation method called garum, which involved fermenting rotten fish, including tuna, to create a popular fish sauce. Although not recommended nowadays, it highlights the different cultural perspectives on consuming fish that may be past their prime.
5. When tuna spoils, it develops a distinctive odor reminiscent of ammonia due to the breakdown of amino acids in the fish. This smell serves as a strong indicator that the tuna is no longer safe to consume and should be discarded.
Dangers Of Eating Expired Canned Tuna
Eating expired canned tuna can have serious consequences for your health. The deterioration of quality and compromised texture and taste are just the tip of the iceberg. The main concern is the potential for food poisoning. If the seal of the can is compromised, the tuna may be exposed to harmful bacteria and other contamination. This can lead to nausea, vomiting, and in severe cases, liver failure. It is crucial to understand that consuming expired tuna can pose a significant risk to your well-being.
Expired canned tuna loses its freshness and can develop an off-odor and an unpleasant taste. The canning process is designed to preserve its quality and flavor, but beyond its expiration date, the tuna may not be at its prime condition. Consuming tuna that is two years old or more is not recommended, as it may not be of good quality or at its peak flavor. The quality and flavor of canned goods can decline, especially between 14 to 24 months after their best by date.

How Does Expired Tuna Cause Food Poisoning?
The growth of dangerous bacteria is the primary cause of food poisoning from expired tuna. Bacteria, such as Salmonella and Listeria, can multiply if the tuna is not stored properly or if it is not handled and cooked correctly. It is important to note that even if the can appears intact, it is still possible for bacterial growth to occur. Damage to the can, such as dents or rust, can lead to compromised security and create an environment that supports microbial growth. It is essential to inspect cans for signs of spoilage, such as bulging or dented cans, an off-odor, discoloration, or separation of the tuna itself.
Food poisoning can lead to various symptoms, including nausea, vomiting, and diarrhea. In addition, headaches, fatigue, dizziness, and a weakened immune system may also be experienced. These symptoms can have a significant impact on your daily life and require medical attention. The risk of food poisoning is a crucial factor to consider when deciding whether to consume expired tuna or to discard it to avoid potential illness.
Proper Storage And Handling Of Canned Tuna
To ensure the safety of consuming canned tuna, proper storage and handling are essential. The shelf-stable canned tuna can be safe to eat for up to three to five years after being opened, depending on storage conditions. However, refrigerated canned tuna should be consumed within two to three days of the expiration date.
It is important to note that these timeframes are general guidelines, and the quality and safety of the product should be assessed based on signs of spoilage.
Before consuming canned tuna, inspect the can for signs of spoilage. This includes checking for bulging or dented cans, as well as any strange appearance or smell. If the tuna has an off smell, sour or ammonia-like odor, or a slimy or discolored texture, it is best to err on the side of caution and discard it.
Properly storing canned tuna in a cool, dry place away from direct sunlight can help extend its shelf life. Once the can is opened, the remaining tuna should be transferred to an airtight container and refrigerated promptly.
Signs Of Spoiled Tuna: What To Look For
The signs of spoiled tuna are relatively easy to spot if one knows what to look for. The most apparent sign is a strong fishy odor, different from the normal smell of canned seafood. Discoloration, such as a change in appearance or texture, can also indicate spoilage. The tuna may become mushy or develop a slimy consistency. These visual and olfactory cues are indicators that the tuna may not be safe to consume. It is crucial to pay attention to these signs and trust your senses when judging the quality of canned tuna.
- Strong fishy odor
- Discoloration
- Mushy texture
- Slimy consistency

Shelf Life Of Different Types Of Tuna
Different types of tuna have varying shelf lives. The canning process preserves the fish, allowing it to last for several years. Shelf-stable canned tuna can last for up to five years if unopened and stored correctly in a cool, dry place. However, it is important to note that the shelf life can vary depending on factors such as the type of tuna, whether it has been cooked before canning, and the storage conditions before opening. Some brands may also have shorter shelf lives due to specific processing techniques.
Fresh tuna, on the other hand, has a much shorter shelf life than canned tuna. It can last up to two days when properly stored in the refrigerator. Frozen tuna, if stored correctly, can last up to six months. Dried tuna has the longest shelf life, lasting up to 10 years if stored in optimal conditions. It is important to note that these timeframes are general guidelines and can vary depending on factors such as temperature, storage conditions, and type of tuna.
- Canned tuna: Up to five years if unopened and stored correctly in a cool, dry place.
- Fresh tuna: Up to two days when properly stored in the refrigerator.
- Frozen tuna: Up to six months if stored correctly.
- Dried tuna: Up to 10 years if stored in optimal conditions.
Note: The shelf life may vary depending on factors such as temperature, storage conditions, and type of tuna.
