Crab is a delicious and nutritious seafood option, enjoyed by people all over the world. However, like any other food, it’s essential to consume it safely and responsibly. When eating crab, there are certain parts that you should avoid to ensure a pleasant and healthy dining experience. In this article, we’ll explore the different parts of a crab that you should not eat and why.
Understanding Crab Anatomy
Before we dive into the parts of a crab that you should avoid, it’s essential to understand the basic anatomy of a crab. A crab’s body is divided into two main parts: the cephalothorax and the abdomen. The cephalothorax is the front part of the crab, which contains the head, thorax, and claws. The abdomen is the rear part of the crab, which contains the digestive organs and the tail.
The Shell and Exoskeleton
The shell and exoskeleton of a crab are not edible and should be avoided. The shell is hard and calcified, making it difficult to digest. Moreover, the shell can cause intestinal blockages or puncture the digestive tract if ingested. The exoskeleton, on the other hand, is the outer covering of the crab’s body, which is also not edible.
The Gills and Gill Rakers
The gills and gill rakers of a crab are also not edible. The gills are the feathery organs that extract oxygen from the water, while the gill rakers are the bony structures that support the gills. Both the gills and gill rakers are located on the sides of the crab’s head and should be removed before cooking.
The Tomalley and Other Internal Organs
The tomalley is the greenish-yellow substance found in the body cavity of a crab. While some people consider the tomalley a delicacy, it’s essential to note that it can contain high levels of toxins and pollutants. The tomalley is the crab’s digestive organ, which filters out toxins and pollutants from the food it eats. However, if the crab has ingested contaminated food, the tomalley can accumulate these toxins, making it unsafe to eat.
Other internal organs, such as the heart, liver, and intestines, should also be avoided. These organs can contain high levels of toxins and pollutants, which can cause food poisoning if ingested.
The Dead Man’s Fingers
The dead man’s fingers are the small, feathery structures found on the underside of a crab’s body. These structures are actually the crab’s lungs, which extract oxygen from the air. While they may look edible, the dead man’s fingers are not safe to eat and should be removed before cooking.
Other Parts to Avoid
In addition to the shell, exoskeleton, gills, gill rakers, tomalley, and internal organs, there are other parts of a crab that you should avoid. These include:
- The eyes and eye sockets, which can be hard and difficult to digest
- The mouth and mouthparts, which can be hard and contain toxins
- The claws, which can be hard and difficult to digest (although the meat inside the claws is edible)
How to Safely Eat Crab
To safely eat crab, it’s essential to follow proper food handling and preparation techniques. Here are some tips:
- Always purchase crab from a reputable source, such as a licensed fish market or a trusted restaurant.
- Store crab in a cool, dry place, such as the refrigerator, to prevent spoilage.
- Before cooking, remove the shell, exoskeleton, gills, gill rakers, tomalley, and internal organs.
- Cook crab thoroughly to an internal temperature of at least 145°F (63°C) to kill any bacteria or viruses.
- Avoid eating raw or undercooked crab, as this can increase the risk of food poisoning.
Conclusion
In conclusion, while crab can be a delicious and nutritious seafood option, it’s essential to consume it safely and responsibly. By avoiding the shell, exoskeleton, gills, gill rakers, tomalley, and internal organs, you can enjoy crab while minimizing the risk of food poisoning. Remember to always follow proper food handling and preparation techniques, and cook crab thoroughly to ensure a safe and enjoyable dining experience.

What are the common mistakes people make when eating crab?
When eating crab, people often make the mistake of not properly cleaning and preparing the crab before consumption. This can lead to a gritty texture and an unpleasant dining experience. Additionally, many people tend to overcook their crab, resulting in tough and rubbery meat.
To avoid these mistakes, it’s essential to properly clean and prepare the crab before cooking. This includes removing the apron, gills, and guts, and rinsing the crab under cold water. It’s also crucial to cook the crab for the right amount of time, usually 8-10 minutes per pound, to ensure that the meat is tender and flavorful.
How do I avoid getting shell fragments in my crab meat?
One of the most frustrating things about eating crab is getting shell fragments in your meat. To avoid this, it’s essential to carefully crack and pick the crab, making sure to remove all shell pieces before serving. You can also use a crab cracker or nutcracker to crack the shell, and then use a fork or pick to gently pull out the meat.
Another way to minimize shell fragments is to use a crab mallet or the back of a heavy knife to gently crack the shell, rather than using your hands or a nutcracker. This will help to break the shell into larger pieces, making it easier to remove them from the meat.
What are the risks of eating undercooked or raw crab?
Eating undercooked or raw crab can pose serious health risks, including food poisoning and parasitic infections. Crab can harbor bacteria like Vibrio vulnificus and Vibrio parahaemolyticus, which can cause symptoms like diarrhea, vomiting, and abdominal pain. Raw or undercooked crab can also contain parasites like Anisakis, which can cause anisakiasis, a gastrointestinal infection.
To avoid these risks, it’s essential to cook your crab thoroughly before consumption. This means cooking the crab until it reaches an internal temperature of at least 145°F (63°C), and making sure that the meat is opaque and flakes easily with a fork. You should also avoid eating raw or undercooked crab, especially if you have a weakened immune system or are pregnant.
How do I store crab to keep it fresh?
Proper storage is crucial to keeping crab fresh and preventing spoilage. When storing crab, it’s essential to keep it refrigerated at a temperature below 40°F (4°C). You can store crab in a covered container or plastic bag, making sure to keep it away from strong-smelling foods, as crab can absorb odors easily.
It’s also important to use crab within a day or two of purchase, as it can spoil quickly. If you’re not planning to use the crab immediately, you can also freeze it, making sure to wrap it tightly in plastic wrap or aluminum foil and store it at 0°F (-18°C) or below.
Can I eat crab that has been frozen for a long time?
While crab can be safely frozen for several months, its quality and flavor may degrade over time. Frozen crab can be safely stored for up to 6-8 months, but it’s best to use it within 3-4 months for optimal flavor and texture.
When freezing crab, it’s essential to follow proper freezing procedures, including wrapping the crab tightly in plastic wrap or aluminum foil and storing it at 0°F (-18°C) or below. You should also label the crab with the date it was frozen, so you can keep track of how long it’s been stored.
How do I handle crab safely to avoid cross-contamination?
Handling crab safely is crucial to avoiding cross-contamination and preventing the spread of bacteria and other pathogens. When handling crab, it’s essential to wash your hands thoroughly with soap and water, and to make sure that all utensils and surfaces are clean and sanitized.
You should also avoid cross-contaminating other foods with crab, especially raw or undercooked crab. This means keeping crab separate from other foods, and using separate utensils and cutting boards when preparing crab. You should also cook crab immediately after thawing, and avoid refreezing thawed crab.
What are the signs of spoiled crab?
Spoiled crab can be identified by its appearance, smell, and texture. Spoiled crab may have a sour or ammonia-like smell, and its meat may be slimy or soft to the touch. The crab may also have visible signs of mold or slime, or its shell may be cracked or broken.
If you notice any of these signs, it’s best to err on the side of caution and discard the crab. Spoiled crab can pose serious health risks, including food poisoning and parasitic infections. It’s always better to be safe than sorry, and to discard any crab that looks, smells, or tastes suspicious.
