But if it’s opened before, then use it within three days after defrosting them at room temperature (not in the microwave oven). If the package is unopened then check its “use by” date carefully and do not use it beyond this date.
Before you buy your frozen fish, make sure that they don’t have any physical changes such as holes, discoloration, and deformations on their surface. Here are a few tips to help you evaluate the safety of frozen fish: There’s no point in trying to cook or eat something rotten and smelly. The most important thing is if after taking your thawed frozen meat out of the refrigerator, you notice that it has a bad smell or taste then just throw it away. Therefore, make sure to date mark your frozen fish with the date you take it out of the freezer and then consume it within 4 months or before its expiration date especially when buying frozen meat from your local grocery store. This is mainly because when exposed to warm temperatures inside our freezers, bacteria responsible for food poisoning will still grow even if you keep them at a temperature below 40 degrees F. So it is important that you keep whatever you put in your refrigerator below 40 degrees Fahrenheit so they won’t grow.Įither way, whenever buying meats like fish from the grocery store make sure you check its expiration date first before purchasing it because once frozen meat has surpassed its expiration date then they will go bad regardless if you put them in the freezer or not. The main cause of spoilage or foodborne illness is due to bacteria growing on surfaces inside refrigerators. While chicken, ground beef, pork, lamb, and veal can each last up to 6 months. How long can you keep fish in the freezer before it goes bad?Īccording to the USDA’s Food Safety and Inspection Service (FSIS), fish can be safely stored in your freezer for about 4 months. However, this does not mean we can keep our thawed fish for more than 2 years because as time goes by bacteria will grow rapidly and affect its quality.Īdditionally, if you find your frozen fish start to smell bad or rancid then it’s best for you to throw them away just like what we do with other foods. 
These compounds help prevent ice crystals from forming in the tissues of fish which would normally cause tissue breakdown during freezing (due to expansion) and thawing (due to contraction). The researchers even said that the reason why frozen fish is still fresh and safe to eat after 12 months of storage in a freezer is due to the naturally contained antifreeze compounds within it. In other words, how long can we safely store fish in our freezer?Īccording to the research done by experts from the marine biology field at Macquarie University in Australia, frozen fish for 12 months will be kept in good condition without any major changes. However, what do we do if after checking the three factors above we find that it is still good? Is this fish also safe for us to eat? Thirdly you can examine its freshness by cutting it open and taste the flesh by slicing a small piece of the meat. Secondly is to check whether there are any changes in its color or texture. For example, you can check the smell of the fish firstly and see if it smells bad. There are many ways to find out whether it is safe or not. Is the fish in the freezer for 2 years safe to eat?
