Crawfish Purging Study

LSU AG Center Study Conclusion
"In conclusion, preparing crawfish for cooking by immersion in a water bath, with or without salt, for a short time will often provide some degree of cleansing, although this is mainly associated with exterior surfaces and the gill cavity where debris can accumulate. The amount of digesta in cooked crawfish subjected to an adequate wash may not be discernible from nonwashed crawfish; however, washing will lessen the amount of debris shed during the cooking process. There is no evidence from this study that suggests the use of salt in cleansing crawfish was beneficial, but results do indicate that a saltwater bath may contribute to increased mortality, if washed crawfish are subjected to refrigerated storage for several days prior to cooking. Conventional commercialstyle purging for 12 hours or longer is the only known way to significantly reduce the size of the hindgut in cooked crawfish, and that method is usually not practical for consumers."

I don't know why this article is just being written now. This study was done about 5 years ago at least and is has been discussed several times on this board.

If you don’t do this you’re a savage.

Thread from 2014 when the results of the study were published
I send the article to anyone who ever claims that purging with salt does anything.

But it does do something, it kills the crawfish before you boil them.

Throwing salt on crawfish before they enter the boiling water is a waste of good salt.
Give em a little bath 1-3x depending on how dirty they are and then throw em in that hot water.

Study was probably funded by the Commercial Purging Lobby

Back in the 70's and 80's my dad would always tell people who did salt baths that they were stupid if they thought it actually purged them internally. So of course that carried onto me and my brothers for some time when we started boiling our own crawfish.

It was done in 2014, but is continuously posted when crawfish starts and people argue about purging.

Oh now we trust the science?
Psssh.
My Pepere and his Pepere used the salt. I’m going to use the salt, me.

My Pop did it religiously, God rest his soul. "The salt makes 'em throw up".
"I hear ya Pop". Lol.

If you read the entire article at the end it says it was published in 2014.

I'm going to continue doing a salt purge for a few reasons.
1) It's tradition, damnit. Why do we have to mess with tradition?
2) Salt is the cheapest part of boiling crawfish.
3) Cleaning them helps them when they are in the boil. One time I did not clean them first and the water looked disgusting when I was done... rather than the normal orange color. Why the hell would I want to boil them in dirt?
There is one thing to be careful of. A few years ago, an old co-worker from Houston called me wanting to know how to boil crawfish. I told him. A few days after he called me and said they were nothing like what he remembered when i would cook them... they were very salty.
We went through what he did... after he put salt in the ice chest to purge... he ran the hose "for like 5 seconds" when I told him to run it for 5 minutes.
