Have you recently purchased seafood but haven’t had the opportunity to consume it yet? Or do you have leftover seafood in your refrigerator and want to know if it is still safe to reheat? These expert tips will help you determine whether your seafood has gone bad or if it can still be consumed.
Best Before Date
Determining the freshness of fish can be a bit confusing, especially when considering the “best before” date. The shelf life of fish can vary widely, ranging from a few days to several months. The freshness of fish depends on various factors, including whether it is cooked, frozen, or fresh. 
When assessing the freshness of fresh fish, the first thing to check is its smell. According to Lyf Gildersleeve, a seafood expert, fresh fish should have a clean, oceanic scent, clear eyes, and bright, shiny flesh.
Importance of Recognizing the Smell of Fresh Fish
Familiarizing yourself with the scent of fresh fish can help you distinguish between fresh and spoiled seafood. Kiki Aranita, a renowned chef and owner of Poi Dog, advises that you can detect spoiled uncooked fish by its strong and putrid smell. If the odor is unpleasant and doesn’t make you want to eat it, trust your senses.
Spoiled fish may also have changes in texture, such as being slimy, less firm, and mushy, and its color may turn gray. Remember, a shiny appearance is good, but the presence of slime is not. Look out for signs such as a sour smell, cloudy eyes, bruising, or slime.
Cooked Seafood
What if you have already cooked a delicious meal and want to know if you can enjoy it again? As a general rule, cooked seafood should be consumed within three days. If you’re unsure how long it has been, you can rely on your sense of smell once again.
Spoiled cooked fish will have a strong odor, a dry texture, and may show signs of mold. When in doubt, it’s better to err on the side of caution and discard the seafood. Eating spoiled fish poses a greater risk to your health than throwing it away when it was still safe to eat.
Ensuring the Safety of Your Seafood
Ensuring the freshness and safety of seafood is crucial. By paying attention to the smell, texture, and appearance of both fresh and cooked seafood, you can make an informed decision about its suitability for consumption. Remember, if you’re uncertain, it’s always better to prioritize your well-being and discard the seafood to avoid potential health risks.
