What Fish is Sushi Grade? A Comprehensive Guide

The term “sushi grade” is frequently used but often misunderstood when it comes to preparing raw fish for sushi and sashimi. It’s not a legally regulated term, but rather an industry standard that implies a certain level of safety and quality for raw consumption. In essence, sushi-grade fish refers to fish that has been handled with specific care from the moment it is caught to minimize the risk of bacteria, parasites, and other potential health hazards. This careful handling process makes the fish safe for eating raw.

Understanding the Concept of “Sushi Grade”

The core idea behind “sushi grade” isn’t about a specific species of fish, but rather how that fish is handled. The goal is to maintain the highest possible level of freshness and safety. Here are the key components that qualify a fish as sushi grade:

Rapid Catching: The fish is caught quickly to reduce stress and potential buildup of lactic acid, which can affect flavor and texture.
Immediate Bleeding: Bleeding the fish immediately after catching helps remove blood, which can attract bacteria and also impact the taste and appearance of the flesh.
Prompt Gutting: Removing the internal organs soon after capture eliminates the source of many bacteria and digestive enzymes that can degrade the quality of the fish.
Thorough Icing: Keeping the fish consistently cold with ice is crucial to inhibit bacterial growth and maintain freshness throughout transport and storage.
Freezing for Parasite Control: Certain species known to carry parasites, such as salmon, are required to be frozen at a specific temperature and for a specific duration to kill any potential parasites. This often involves freezing at 0°F for 7 days or flash-freezing at -35°F for 15 hours.

While these practices are the foundation of the “sushi grade” designation, it is also about overall quality. The fish should be fresh, vibrant in color, and have a pleasant, clean smell.

Common Sushi Grade Fish

While almost any fish can, technically, become “sushi grade” through careful handling, some are more commonly used and known for their suitability for raw consumption. Here are some of the popular ones:

Tuna: Tuna, particularly albacore, bigeye, bluefin, bonito, skipjack, and yellowfin, are considered relatively safe to eat raw with minimal processing because of their resistance to parasites. This makes it a top choice for sushi and sashimi.
Salmon: Although popular, salmon does carry the risk of parasites. Farmed salmon is generally considered safer because it is raised on parasite-free feed, but both wild and farmed salmon should be frozen using the guidelines outlined above before consumption.
Seabass: A mild-flavored and firm-textured fish, often safe to eat raw when handled appropriately.
Swordfish: Another popular choice for sashimi due to its meaty texture and flavor.
Mackerel: While some types of mackerel can be eaten raw if handled correctly, such as Saba, it may require curing or other treatments.
Scallops: Often used in sushi and sashimi, scallops are generally safe to eat raw.

It’s also important to note that seafood like shrimp, crab, eel, and octopus are commonly eaten in sushi but are typically cooked before being used.

The Reality of “Sushi Grade”

It is essential to understand that the term “sushi grade” is not regulated by any governing body. This means that different suppliers may have varying standards. The best way to ensure the fish you’re using is safe for raw consumption is to:

Buy from reputable suppliers: Opt for well-known seafood markets or Japanese specialty shops that have a reputation for handling fish properly.
Ask questions: Don’t hesitate to ask vendors about how their fish is caught, handled, and whether it has been frozen.
Use your senses: Look for fish with bright color, firm flesh, and a fresh smell. Avoid fish with a fishy odor or a dull, slimy appearance.

Grocery Store Fish and Sushi

Can you use regular grocery store fish for sushi? Yes, it’s possible, as long as the fish is either labeled “sushi grade” or has been previously frozen. Freezing is a critical step for destroying parasites, making it reasonably safe for raw consumption. However, the taste and texture might not be as high as fish purchased directly from a reputable source specializing in sushi-grade fish.

FAQs about Sushi Grade Fish

Here are some frequently asked questions to help clarify the nuances of “sushi grade” fish:

1. Is all tuna sushi grade?

Not necessarily. While tuna is often considered safe to eat raw, it must still be handled properly to qualify as “sushi grade.” This means it should be quickly caught, bled, gutted, and iced appropriately.

2. Is farmed salmon safer than wild salmon for raw consumption?

Yes, farmed salmon generally poses a lower risk of parasites because it is raised on feed pellets, preventing them from eating parasite-infected prey. However, both should be frozen using appropriate methods before raw consumption.

3. Can I use regular salmon from the grocery store for sushi?

It’s not advisable to use regular, unfrozen grocery store salmon for sushi unless it’s explicitly labeled “sushi grade” or is known to have been flash-frozen.

4. How can you tell if fish is sushi grade?

Look for bright colors, firm texture, a fresh sea-like smell, and ask the vendor about the fish’s origin, handling, and whether it has been frozen.

5. Can I make regular fish sushi-grade at home?

You can make regular fish “sushi grade” by freezing it at 0°F for 7 days or flash-freezing at -35°F for 15 hours. This will kill any potential parasites.

6. Is Costco fish sushi grade?

Some Costco fish can be used for sushi if you’re comfortable with a certain level of risk. It is recommended to check product labels, look for freezing indicators, and proceed cautiously.
