How Long Is Raw Grouper Safe to Eat?
How long does raw grouper stay fresh?
Raw grouper is safe to eat for 1–2 days when stored in a refrigerator at or below 40°F (4°C).
Fresh raw grouper is a prized, firm-fleshed fish, but its high moisture content makes it highly perishable. To maintain safety and quality, you must maintain a strict cold chain by storing the fish in the coldest part of your refrigerator at or below 40°F (4°C). Because bacteria can multiply rapidly on raw seafood, moving beyond the two-day window significantly increases the risk of foodborne illness. Proper handling—such as using airtight containers and preventing cross-contamination with other foods—is essential for keeping this fish safe until it reaches your pan. Always prioritize scent and texture when determining if your seafood is still fit for consumption.
