Yes, purging crawfish is a myth. According to Dr. Greg McClain of the LSU AgCenter, research shows that salt provides no effective cleansing benefits when added to the wash water before boiling. The best way to clean crawfish is to rinse them in cold water several times and then move on to cooking.
Crawfish season is here, and it’s time to start preparing the delicious crustaceans. But is purging crawfish necessary? And is it a myth or fact? In this blog post, we’ll explore the truth behind purging crawfish and what happens if you don’t purge them. We’ll also look at why you can’t eat dead crawfish, what happens if you use salt as a purging method, and why straight tail crawfish are a myth. Finally, we’ll discuss blue crawfish meat and how long to purge crawfish before cooking. By the end, you’ll know whether purging crawfish is a myth or fact.
What Is Purging Crawfish Necessary?
Purging crawfish is important to remove dirt, debris and other substances from their digestive tract before cooking. The process involves flushing them with cold, oxygenated water for several hours, which also helps reduce the size of the crawfish’s hindgut. Doing so yields cleaner, more flavorful crawfish that are a delight to eat.
Purging crawfish is a necessary step in preparing the crustacean for consumption, and there are several compelling reasons why it should be done.
Reasons for Purging Crawfish
Purging crawfish is an important step in the preparation of crawfish for cooking. Without it, the crawfish can contain harmful bacteria and parasites that can cause food-borne illnesses if consumed.
The primary reason for purging crawfish is to remove any contaminants that may have been present in the water where the crawfish were caught. This includes sediment, organic matter, and bacteria, which can all be present in the water and can contaminate the crawfish.
It is also important to purge crawfish to reduce the levels of ammonia, nitrates, and phosphates, which can be harmful to humans if consumed. Purging the crawfish also helps to remove any mud and dirt that may have been taken up by the crawfish while they were in the water.
Finally, purging crawfish helps to remove any parasites that may have been present in the crawfish’s environment. Parasites can be dangerous to humans if ingested and can cause serious health issues, so it is important to properly purge the crawfish before cooking.

It is still important to cook the crawfish thoroughly to ensure that any potential bacteria or parasites are killed. Additionally, the saltiness of the crawfish may not be to everyone’s taste.
Why Can’t You Eat Dead Crawfish?
Eating dead crawfish can cause food poisoning due to the rapid growth of bacteria such as Vibrio. This bacteria multiplies quickly and can cause serious health issues. Dead crawfish also start to break down into ammonia, which can make the meat mushy or crumbled. To avoid food poisoning, it is best to only eat live crawfish.
Despite what some may believe, purging crawfish prior to consumption is not a myth; instead, it is a critical safety measure to reduce the risks and dangers of eating dead crawfish.
Risks and Dangers of Eating Dead Crawfish
The short answer to the question of why you can’t eat dead crawfish is because there are certain risks and dangers associated with doing so. Eating dead crawfish can lead to food poisoning, as the meat may contain bacteria that could make you ill. In addition, eating a dead crawfish may also introduce parasites into your body, as crawfish can carry these organisms.
Furthermore, the act of purging dead crawfish is a myth. Purging is the process of removing the mud and sand from the crawfish’s intestinal tract by allowing the crawfish to live in clean, fresh water for a period of time. This method is ineffective and can actually increase the risk of food poisoning. Therefore, you should never attempt to purge a dead crawfish.
In conclusion, the risks and dangers associated with eating dead crawfish should not be taken lightly. Doing so may lead to serious health issues, including food poisoning and the introduction of parasites into your body. Thus, it is best to err on the side of caution and avoid eating dead crawfish.
Salt Becomes a Bad Method of Purging
As purging crawfish with salt has become increasingly popular, it is important to understand why salt is not the best solution for purging. Let’s examine the reasons why salt becomes a bad method of purging.
Reasons Why Salt Becomes a Bad Method
Although salt is a commonly used method to purge crawfish before cooking, it is not always the best option. Here are some of the reasons why salt is not as effective for purging crawfish as some may think:
1. Salt can dry out the crawfish, making them tough and unpalatable. The salt draws moisture out of the crawfish, leaving them dry and unappetizing.
2. Salt can damage the delicate tissue of the crawfish, resulting in an unpleasant texture.
3. Salt can increase the risk of contamination. Since crawfish can absorb salt and other contaminants, salting them before cooking can increase the risk of contamination from harmful bacteria.
4. Salt can cause bitterness. Too much salt can lead to a bitter flavor in the crawfish, making them less enjoyable to eat.
For these reasons, it is important to consider other options for purging crawfish before cooking. An alternative that has been proven effective is to submerge the crawfish in clean, fresh water for a few minutes before cooking. This method is safe, effective, and will help ensure that the crawfish are as fresh and flavorful as possible.
What Happens If You Don’t Purge Crawfish?
If you don’t purge crawfish, there is an increased risk of ingesting bacteria, parasites, and other toxins. Purging helps to remove impurities and sediment that can lead to foodborne illnesses. To ensure safe consumption, live crawfish should be flushed with clean water for several hours.
Despite the potential risks and dangers of not purging crawfish, some people still believe that purging is only a myth. Let’s explore further and examine the potential risks of not purging crawfish.
Potential Risks and Dangers
If you do not purge crawfish before consuming them, you risk ingesting a variety of bacteria that can cause serious health issues. These potential risks and dangers include food poisoning, gastrointestinal illnesses, and other adverse reactions. Moreover, the presence of heavy metals, such as cadmium, arsenic, and lead, can also be present in crawfish and can cause long-term health problems if consumed. As a result, it is essential that you properly purge crawfish of any contaminants before eating them.
How Long To Purge Crawfish Before Cooking
Purging crawfish before cooking is important to remove dirt and debris. The LSU AgCenter recommends a 12-24 hour water bath for commercial purging. However, crawfish can self-purge within 24-36 hours without water. Soaking in saltwater is unnecessary and not effective.
Before taking a closer look at the recommended time frame for purging crawfish, it’s important to consider whether or not purging is even necessary.
Recommended Timeframe
When it comes to purging crawfish, the recommended timeframe is a critical factor in the process. Purging crawfish involves removing the dirt and bacteria from their shells, which can take anywhere from four to eight hours. The longer the crawfish are purged, the cleaner and more flavorful they will be.
It is important to note that the purging process should be kept at a temperature of approximately 60°F to ensure that the dirt and bacteria are removed without killing the crawfish. This is why many experts recommend purging crawfish in a large container filled with cool, running water.
Once the crawfish have been purged for the recommended timeframe, they should be cooked immediately to ensure food safety. If the crawfish are not cooked within two hours of purging, they should be discarded.
In conclusion, purging crawfish is not a myth, but a necessary process to remove dirt and bacteria before cooking. The recommended timeframe for purging crawfish is between four to eight hours, however, the crawfish should be cooked within two hours of purging to ensure food safety.
Purged Crawfish vs Unpurged
To gain a better understanding of the differences between purged and unpurged crawfish, let’s explore the key characteristics of each.
Differences Between Purged and Unpurged Crawfish
When it comes to crawfish, purging is an essential step in the process of preparing and cooking them. The difference between purged and unpurged crawfish lies in the amount of time the crawfish are given to expel the impurities and waste from their bodies. Purged crawfish are submerged in cold water, which causes them to release the waste from their bodies. Unpurged crawfish, on the other hand, have not been exposed to the cold water and still contain the debris and impurities inside their bodies.
The main difference between purged and unpurged crawfish is the level of contamination. Purged crawfish are considered cleaner and safer to eat, as they are free of any impurities. Unpurged crawfish, however, contain harmful bacteria and other contaminants that can make you sick. For this reason, purging is highly recommended when preparing crawfish, especially when eating them raw.
Another key difference between purged and unpurged crawfish is the taste. Purged crawfish are often considered more flavorful and have a sweeter taste, while unpurged crawfish can be more bland and off-tasting. Since purging helps to remove the impurities from the crawfish, this can also help to improve the overall taste.
In conclusion, it is important to understand the differences between purged and unpurged crawfish. Purged crawfish are considered cleaner and safer to eat, and often have a more delicious flavor. Unpurged crawfish, however, can contain harmful bacteria and other contaminants, and can be more off-tasting. Therefore, purging is essential when preparing crawfish, as it helps to improve the taste and safety of the dish.
Straight Tail Crawfish – Myth or Fact?
To better understand the truth behind straight tail crawfish, it is important to examine the process of purging and its potential effects.
Exploring the Truth Behind Straight Tail Crawfish
When it comes to the crawfish industry, there has long been a myth that purging straight tail crawfish with saltwater is a necessary and effective method. While purging crawfish does have some benefits, the truth is that it is not always necessary, nor is it always effective. To accurately explore the truth behind straight tail crawfish, it is important to understand the different purging methods, the advantages and disadvantages of each, and when purging may be beneficial.
