What to do if you are poisoned by crayfish

How to boil crayfish in water, how much salt?

Hidden in the lifestyle of representatives of these crustaceans is the answer to the question that worries almost everyone, whether it is possible to boil dead crayfish.
Of course, if they were cooked alive, then they are very tasty and even healthy. But the dead ones are not only not so tasty, but can even pose a certain threat to human health.

The main reason is their diet. Since crayfish do not disdain carrion, many different, including quite harmful, microbes accumulate in their organs, some of which are extremely dangerous. After death, crayfish carcasses quickly decompose and become rotten. This can be determined by an unpleasant specific smell. But if you cook and eat a dead crayfish, you may, at best, get poisoned. In the worst case, the consequences can be much more severe.

Improper storage of crayfish will lead to the death of many individuals.

Many people, when boiling dead crayfish, add salt and various spices in the hope of eliminating the unpleasant smell. But this is also dangerous, because even if you can cope with the smell, you will not be able to improve the quality of the meat and kill harmful microorganisms. As a result, do not regret wasted time and effort, but simply throw away your catch and do not put your health in danger.

We hope that, as a result, you should not cook dead crayfish, you understand. Don't try to experiment! The price of such experiments is your health or the health of those you will treat. It’s better to work hard and catch more crayfish, or just spend more money and buy it.

Bon appetit, eat only quality foods!

Rules for boiling crayfish

  • Cooking time for crayfish can range from 15 to 25 minutes. The time period will depend solely on the size of this aquatic inhabitant. For small specimens, 15 minutes are enough to reach readiness, but large crayfish need to be boiled for at least 20
  • But, if for some reason you missed the moment and did not note the time, then you can use the hint that our great-grandfathers used. As soon as this aquatic resident changes its swamp-green color to bright red, then it’s time to get it out of the boiling water
  • The taste of this delicacy is greatly influenced by the amount of salt in the cooking broth. If you overdo it with this component or do not add the required amount, the finished dish will turn out to be unsuitable for consumption.
  • In order for the beer snack to be tasty, you need to put 1 tbsp for each liter of broth. l salt. And even if such a quantity of this product scares you, crayfish will take exactly as much salt as they need

Live crayfish is the guarantee that its meat will have excellent tasting qualities.

  • Crayfish are a fairly perishable product, so you should choose only live ones for cooking. The main indicator of the freshness of an arthropod is an elastic, bent tail pulled up to the abdomen. If you are offered to buy a crayfish with a completely relaxed body and claim that he is sleeping, then simply refuse the purchase.
  • After all, if a deceased river resident lay on the counter for more than 3 hours, then with a high probability we can say that his meat has already begun to deteriorate. But even if the seller managed to deceive you, and you brought home a not entirely fresh product, carefully monitor it during cooking
  • Literally a few minutes after falling into boiling water, a spoiled crayfish will float up, swell a little and begin to emit not very pleasant odors. Such a product must be immediately removed from the brine, otherwise it will spoil the taste of other, quite normal arthropods

Dead crayfish meat, even after heat treatment, can be harmful to human health

Remember, no matter what anyone says, boiling dead crayfish and eating them is strictly prohibited. And the point here is not that the taste of meat in such arthropods deteriorates. In nature, crayfish are considered the orderlies of rivers and lakes, and due to the fact that they feed exclusively on carrion and dead shellfish, quite a lot of harmful substances accumulate in their bodies.

They do not pose a particular danger to the cancer itself, but as soon as it dies, they literally from the first minutes begin to decompose its tissues. Therefore, even if you boil its meat a little more than required, you are unlikely to be able to get rid of pathogenic microflora. But it’s over, if you take a chance and eat such a product, you will most likely get poisoning and an upset stomach.

Boil the crayfish for about 30 minutes until the crayfish is completely shitty.

  • As mentioned a little above, you need to cook the crayfish until tender for about half an hour. Of course, if the arthropod is small in size, then 10 minutes will be enough for it to reach readiness. But if you are lucky and you were able to get really large specimens, then keep them in boiling water for at least 25 minutes
  • Moreover, this does not mean at all that they should be cooked at the highest possible temperature all this time. You can prepare a fragrant broth, dip the crayfish into it (it’s best to lower them head down), boil them for literally 15 minutes, and then turn off the heat completely
  • If you leave these river inhabitants in the hot broth for another 10-15 minutes, they will cook perfectly and you will get a dish with very tender and flavorful meat

Crayfish cooked with dill

If you want the crayfish to be saturated with the aroma of dill as well as possible, then first cook a spicy, rich broth from it and only then dip the arthropods into it.


  • Fill a saucepan with 3 liters of water and place it on the stove
  • Add 3 tbsp to it. l salt, 4 pcs. bay leaves and 300 g fresh dill
  • Bring the liquid to a boil, simmer for 10 minutes, then turn off the heat and let the broth brew
  • When the spices release their aroma, return the pan to the stove and bring the liquid to a boil.
  • Dip the prepared crayfish into the boiling broth and boil them for 15-20 minutes

Crayfish are a fairly perishable product, so you need to select only live specimens for cooking. The main indicator that an arthropod is fresh is the presence of an elastic, bent tail pulled into the abdominal area. In the case where the seller offers completely relaxed crayfish, claiming that they have fallen asleep, it is better to refuse such a purchase.

When a dead river arthropod has been in the store for more than 3 hours, it has most likely already begun to deteriorate. If the seller nevertheless tricked you into purchasing such products, you need to diligently monitor the crayfish during the cooking process.

If the cancer has already deteriorated, a couple of minutes after it gets into boiling water:

  • will float up;
  • will be slightly swollen;
  • It will smell very unpleasant.

Such a crayfish should be immediately removed from the water, since it can cause damage to other, completely normal arthropods.

Many people wonder why you can’t boil dead crayfish. This is primarily due to their diet. Such arthropods do not refuse carrion as food; all kinds of microorganisms, and quite harmful ones, accumulate in their bodies in large quantities, and some of them are very dangerous.

When an arthropod dies, its body quickly begins to decompose and rot. You can find out by sniffing the river inhabitant - it will emit an unpleasant, specific aroma. If you cook a dead arthropod, the most harmless consequence will be poisoning.


Some people still try to cook dead crayfish, adding salt and all kinds of seasonings to get rid of the unpleasant aroma. However, this should not be done, since although it is still possible to get rid of the smell, it is unlikely that it will be possible to cope with the dangerous bacteria that have settled in the meat of the arthropod. Therefore, you should not waste time and effort on catching crayfish; it is better to simply throw them away and not endanger your own body.

Once you understand why you can't cook dead crayfish, you most likely won't want to experiment with your health. If the catch could not be prepared in time, it is better to start catching arthropods again, or purchase them at the store. To do this, you can visit a specialized store. In addition, if you do decide to purchase crayfish in the store, be sure to choose only fresh product. In this case, you will definitely be able to enjoy a delicious dish without harming your own health.

Despite the wide list of positive qualities, this product also has certain contraindications for use, which you should definitely be aware of.

Excessive consumption of crayfish can cause allergic reactions, which is why they should be eaten in moderate doses. It is strictly forbidden to eat dead crayfish, as there is a high probability of poisoning. For a person with an individual intolerance to the product, such a delicacy can pose a serious danger.

Pregnant women should definitely limit their use of this product to avoid the possibility of developing allergic reactions. Despite the high biological value of crayfish, they are contraindicated for women during lactation. Also, crayfish meat is not recommended for children under three years of age. The reason for this is again the likelihood of allergies, which will negatively affect the child’s health.

In conclusion, it should be said that the benefits and harms of crayfish are two closely related concepts. That is why you need to carefully consider your decision before consuming this product. But, as practice shows, the benefits of this product far exceed its contraindications. Due to its valuable composition, as well as the substances that are found in the cover of crayfish, this product has been successfully used in medicine, dietetics, and cosmetology for many years in a row.

Having brought the water to a boil, it is necessary to begin immersing the arthropods in the seething liquid, one at a time and upside down. If you fill them all up, this will reduce the temperature of the water, the boiling will stop and the crayfish will crawl along the bottom, dying for a long time and painfully. This is impractical not only for humane reasons, but also because it will negatively affect the quality of the meat. How long to cook crayfish after boiling? Arthropods should simmer in a saucepan for 10–15 minutes, without a lid. They need to be stirred periodically.

It’s easy to understand why crayfish are included in the list of delicacies not only for adults. Despite the fact that the insignificant amount of meat that has to be extracted from under the dense shell causes more trouble than pleasure, this delicacy is still considered not only tasty, but also dietary. Why?

  1. This is a low-calorie product - 100 grams contain only 78-90 calories.
  2. The meat of this animal contains B vitamins (B1, B12, B6, B2), which have a positive effect on the nervous and digestive systems and improve the functioning of the gastrointestinal tract.
  3. Crustaceans live in almost pure water, which indicates the quality of the product.
  4. In addition to vitamins D, C, E, K, protein also contains many useful microelements: calcium, magnesium, nickel, fluorine, chromium, iron, sulfur and many others. They improve metabolism and normalize the functioning of internal organs.

If meat is so healthy, why does crayfish poisoning occur? Is this possible in principle?

Healthy and high-quality protein from crayfish meat sometimes leads to health problems. Of course, death from crayfish poisoning is an extremely rare condition, but anything can happen if these crustaceans are consumed incorrectly. What are the consequences after eating cancer meat?

  1. Allergic reaction to the product. Despite the almost ideal composition, the meat is identical to other crustaceans that live in the sea. Reactions often develop to them. Allergies occur especially often in childhood.
  2. Food poisoning with crayfish, possibly due to a poor-quality product. They need to be cooked while still alive, otherwise there is a high probability that the meat will be slightly spoiled. This is a perishable product and must be consumed as soon as possible after cooking to avoid developing a food infection.
  3. An important condition for storing already cooked crayfish is clean glassware. In aluminum, due to the high sulfur content, meat quickly oxidizes and spoils.
  4. People with thyroid diseases should not eat this product - the course of disease processes worsens, and some diseases become aggravated.

When crayfish poisoning occurs, symptoms and treatment depend on the type of health problem.

  1. With food poisoning, nausea, repeated vomiting, weakness, abdominal pain along the intestines, and stool disturbances appear. Possible fever, dizziness, headaches, rapid heartbeat, lack of appetite. Manifestations depend on the amount of product eaten and on the individual characteristics of the body. With a mild degree, a person can get by with just nausea and weakness.
  2. The development of allergic reactions to crustacean protein also occurs in different ways. Here, the symptoms of crayfish poisoning can change before your eyes. Mild itching of the skin and minor rashes such as urticaria quickly go away when this dish is discontinued. But if the meal continues, the rash begins to intensify, covering almost the entire skin, and sometimes the mucous membranes.
  3. In rare cases, the reaction to the protein is so strong that the person experiences a feeling of lack of air, swelling of the laryngeal mucosa begins and anaphylactic shock develops.


What to do if you are poisoned by crayfish? If you are lucky and the health problems are minimal, you just need to completely cancel this dish.

For mild food poisoning without fever and significant health problems, you can take medications that normalize intestinal microflora and antibacterial substances.

An allergic reaction such as urticaria is treated with antihistamines and eliminating crustacean protein from the diet.

Severe food infection and severe allergies are indications for immediate hospitalization of a person.

This is the only possible treatment for crayfish poisoning. You should not hope that the strongest medications at hand will help. In the case of anaphylactic shock, death can occur in a matter of minutes.

How to prevent health problems when eating crayfish meat?

  1. Eat only fresh produce. It is better to cook live crayfish.
  2. You should not put cooked meat in aluminum dishes; give preference to glass or ceramic ones.

How to deliciously cook crayfish in milk?

Garlic has chelating properties, which is the ability to bind toxins, including, for example, the potentially carcinogenic cadmium from cigarette smoke, and remove them from the body. It also activates white blood cells, which engulf and destroy cancer cells. One of the most common types of cancer is stomach cancer, but regular consumption of garlic and onions reduces the likelihood of this disease. Garlic also serves as a source of sulfur, which is necessary for the liver to perform its detoxifying function.

Onions act in a similar way, although to a lesser extent. Both garlic and onions contain allicin, a sulfur-containing substance that has a powerful detoxifying effect. Considering that the liver is a universal organ that cleanses our body of any carcinogens and pathogens, the importance of onions and garlic cannot be overestimated.

Why do people get poisoned?

It doesn't happen often, but it does happen. So, let's look at the factors that put our health at risk when eating crustacean meat.

After catching, animals should not be placed in aluminum or galvanized containers. During the interaction of zinc or aluminum with crayfish, the latter become infected with metal ions, which then negatively affects the health of the person who has eaten such crayfish.

From zinc and aluminum poisoning, organs such as the heart, kidneys and liver are primarily affected. So, when planning to catch crayfish, it is better to prepare plastic, plastic or glass containers for storing them.

During the period between catching and cooking, the animals must remain in the water. Otherwise they will die. And already in the first hours after death, their meat begins to decompose and, accordingly, becomes unsuitable for consumption, and, more precisely, dangerous to health.

Remember: dead crustaceans should never be cooked. And cooked arthropods must be eaten within two to three hours, otherwise they again begin to deteriorate, and there is a risk of poisoning from such meat.

Also, do not forget that a person may be allergic to crayfish. Reactions to arthropod meat can range from minor skin rashes to anaphylactic shock, which can lead to suffocation and death. Most often, intolerance to crustacean meat occurs in young children.

A disease such as paragonimiasis can be a consequence of eating a river delicacy. Paragonimiasis is an infection transmitted by crustaceans. This infection primarily affects the lungs, and also the human brain and liver.

If you have problems with the thyroid gland, delicacy in the form of arthropod meat is contraindicated for you, because it significantly negatively affects the functioning of this organ. So after eating crayfish, the disease may worsen.

  • in a cold room with a high level of moisture (basement, cellar)
  • in a refrigerator.

Is it possible to boil dead crayfish caught yesterday?

Reservoirs are not always located close to home, and therefore fishermen often have to leave for a day or two to bring back a lot of catch. Fishermen may have a question: is it possible to boil dead crayfish caught yesterday?

Tip: Boil the crayfish immediately after catching. If this is not possible, then put them in a cold place, and then cook as usual.

The prey will be perfectly preserved if it is covered with ice. You can bring frozen water cubes with you when you go fishing in a special thermal container.

Remember: You cannot cook dead crayfish that have died naturally. You only need to catch arthropods alive!

You should know: There is one way to check whether crayfish were cooked alive or already dead: if they have a tucked tail when cooked, then the crayfish was cooked fresh.

This is due to the fact that when a live crayfish is thrown into boiling water, it curls its tail into a ball. This method is used to determine the freshness of the preparation of these arthropods in cafes and restaurants.

Features of choosing live crayfish

In a large fish store you can find an aquarium with live arthropods. In order not to make a mistake with your choice, you need to know the features of the appearance of healthy crayfish.

  • The color of living individuals is green with a blue tint or brown, always even throughout the entire carapace.

  • There should be no damage or foreign growths on the shell and claws.
  • Cancers should actively move, move their whiskers and limbs.

Some sellers convince that the arthropod simply fell asleep and the “sleep” will not affect the quality. This is wrong.
