I bought salmon a week ago and wanted to make it for dinner today. When I took it out of the refrigerator, it had a yellow stain on it. What is it?

How to Store Salmon Properly Next Time

✔ Use within 24–48 hours of purchase
✔ Store in the coldest part of the fridge
✔ Keep tightly wrapped or sealed
✔ Freeze immediately if you won’t cook it soon

Final Verdict

The yellow stain on your salmon is most likely caused by fat oxidation and spoilage. Since it’s been refrigerated for a week, it’s safest not to eat it.

If you’d like, I can also:

• Explain how long cooked salmon lasts
• Share safe thawing methods
• Help with meal planning to avoid food waste
• Provide signs of frozen fish spoilage

Just let me know 🐟
