Frequently Asked Questions

Can you eat fish 3 days after buying it?

It's not recommended. Fresh fish should be used within 1-2 days of purchase. After 3 days, the risk of spoilage and foodborne illness increases significantly, even if refrigerated properly.

How can you tell if frozen fish is still good?

Good frozen fish should have no strong odor, minimal ice crystals, and firm flesh. Avoid fish with freezer burn (white spots), strong fishy smell, or soft, mushy texture when thawed.

Is it safe to refreeze fish that has been thawed?

No, you should never refreeze fish that has been thawed. This can lead to bacterial growth and significantly compromise both quality and safety. Cook thawed fish within 1-2 days.

What's the difference between sushi-grade and regular fish?

Sushi-grade fish has been frozen at specific temperatures to kill parasites and is handled with extra care. It should be used the same day of purchase and stored at very cold temperatures.

How should you store fish if you don't have ice?

Store fish in the coldest part of your refrigerator (usually the back of the bottom shelf). Wrap tightly and place on a plate to catch drips. Use within 1-2 days maximum.
