It smells bad when thawed
If you have thawed something and you noticed a strange smell, you should not eat or cook that food, because it may be affected by the fact that you have not frozen it properly or it has actually expired.
“This is a case where you should use your senses. If the item smells wrong when thawed, then throw it out. It might not be harmful, but it definitely won’t be tasty,” Lam says.
“Airtight storage is your best friend when it comes to freezing. It will ensure longer shelf life and a higher quality of a product,” Palafox says.
