How we tested spoilage

We purchased commercially frozen raw grouper and stored it in our freezer at 0°F (-18°C). After holding the samples for 90 days, we removed several pieces for testing. Upon inspection, we noted a slight change in appearance, with some fillets showing minor discoloration. The texture was firm, but we detected a faint, unpleasant smell that raised concerns. To further verify, we cooked a sample to an internal temperature of 165°F (74°C) and observed no significant improvement in smell or texture. Given our observations, we decided to discard all samples that exhibited any signs of spoilage to prioritize safety.
