LOL, Debs, don't worry about it. It's usually me who does things like that.

No, I've never been sickened by raw kidney beans because I always cook them first. Smile

But really, this is not an urban legend, it's the real deal. There is a high concentration of lectin toxin in kidney beans, and they should be cooked at boiling temps for at least ten minutes before eating. It is not safe to cook them from the fresh state in crockpots unless you cook them on high and let them boil.

Here is an article from foodreference.com:

RED KIDNEY BEAN POISONING

Red Kidney Bean Poisoning is an illness caused by a toxic agent, Phytohaemagglutnin (Kidney Bean Lectin). This toxic agent is found in many species of beans, but it is in highest concentration in red kidney beans (Phaseolus vulgaris). The unit of toxin measure is the hemagglutinating unit (hau). Raw kidney beans contain from 20,000 to 70,000 hau, while fully cooked beans contain from 200 to 400 hau. White kidney beans, another variety of Phaseolus vulgaris, contain about one-third the amount of toxin as the red variety; broad beans (Vicia faba) contain 5 to 10% the amount that red kidney beans contain.

As few as 4 or 5 beans can bring on symptoms. Onset of symptoms varies from between 1 to 3 hours. Onset is usually marked by extreme nausea, followed by vomiting, which may be very severe. Diarrhea develops somewhat later (from one to a few hours), and some persons report abdominal pain. Some persons have been hospitalized, but recovery is usually rapid (3 - 4 h after onset of symptoms) and spontaneous.

The syndrome is usually caused by the ingestion of raw, soaked kidney beans, either alone or in salads or casseroles. As few as four or five raw beans can trigger symptoms. Several outbreaks have been associated with "slow cookers" or crock pots, or in casseroles which had not reached a high enough internal temperature to destroy the glycoprotein lectin. It has been shown that heating to 80 degrees C. may potentiate the toxicity five-fold, so that these beans are more toxic than if eaten raw. In studies of casseroles cooked in slow cookers, internal temperatures often did not exceed 75 degrees C..

All persons, regardless of age or gender, appear to be equally susceptible; the severity is related only to the dose ingested.

No major outbreaks have occurred in the U.S. Outbreaks in the U.K. are far more common, and may be attributed to greater use of dried kidney beans in the U.K., or better physician awareness and reporting.

NOTE: The following procedure has been recommended by the PHLS (Public Health Laboratory Services, Colindale, U.K.) to render kidney, and other, beans safe for consumption:
* Soak in water for at least 5 hours.
* Pour away the water.
* Boil briskly in fresh water for at least 10 minutes.
* Undercooked beans may be more toxic than raw beans.

HELP!! I thought beans were supposed to be easy!!?? I have a square of bush beans whose leaves are turning from healthy green to a yellowish color. I always do the 2" finger test before watering, so they're not too wet. They're planted in a separate box next door to a box with marigolds which I've heard are not friendly to peas or beans, and the other plants in the same box aren't do too well either---radish leaves are full of holes and they're turning yellow, and the other squares consist of a cucumber and a cilantro that bolted (I pulled it out) Any ideas?

I had this problem, too. I fed them everything I could think of - fish emulsion, epsom salts, cal/mag pills, gypsum and miracle grow. The only thing I did not give them was iron. They greened up a bit, but not much. However, they are producing beans just fine so I decided to cease worrying about it.

Coot, are you using Mel's Mix?

I am using a fudged version that uses vermiculite, peat, manure/humus, and a bit of our good ol' Virginia red clay. I tested my soil yesterday morning. The pH was low-ish (6+), potash was fine, but both phosphorus and nitrogen were very low. (And that after hitting my SFGs with a heavy layer of coffee grounds, twice! Guess it breaks down even more slowly than I thought.) I am going to be spreading bone meal and blood meal this morning. My plants all look fine so far, but I am paranoid.

Since we are so close geographically, if you are using any of your topsoil, you may be having a similar problem with your soil chemistry. Even if you ARE using MM, it might be worth it to test your soil, as it seems like a lot of people on the forum have had trouble with their compost.

Hi Megan, I am using MM. All my veggies are grown in boxes with bottoms. Funny thing is, a couple of the bean plants in that box didn't germinate, so I stuck in some new seeds a few weeks later and those particular plants look fine. I was wondering if it was an age thing or perhaps the new plants are sucking up all the nitrogen.

Where did you take your soil to be tested and do they charge a fee for that?

I bought a kit at HD, it was about $3. It may not be as precise as an Ag Extension office test, but it was quick and told me what I needed to know.

I direct-seeded almost all my plants, too, and they were slow to germinate. I think it is the wacky spring we are having. Despite my soil being off, they seem healthy.
