Hello! Fishballs, like any other food, have a limited shelf life even when stored in the freezer. While frozen food can technically last indefinitely in the freezer in terms of safety, the quality and taste may deteriorate over time.
If your fishballs have been in the freezer for several months, they might still be safe to eat as long as they have been kept at a consistent, low temperature. However, the texture and flavor may not be as good as when they were fresh.
To check if the fishballs are still safe to eat, you can look for signs of freezer burn, such as dry spots or ice crystals forming on the surface. If the fishballs show signs of freezer burn, their quality may be compromised, but they are still safe to consume.
It's always best to use your judgment and trust your senses when it comes to frozen food. If the fishballs look and smell okay after thawing, you can cook them thoroughly and give them a taste test. If they have an off smell, slimy texture, or unusual color, it's best to discard them to avoid any risk of foodborne illness.
Remember, when in doubt, it's better to err on the side of caution and prioritize food safety. Enjoy your fishballs!
