Navy beans- soaked two night now smell HORRID!

So I intended to make them yesterday but after swimming and spending time in the sun I was worn out. I took the lid off of them this morning after they had been soaking for 2 nights and they smelled like dirty diapers, oriental market, portapotty- you name it but the smell was TERRIBLE! I rinsed them very well and added new water and they are now simmering. Do you know if they are bad (I tasted one and it was ok) or will they be fine after I make them into boston baked beans?

      (things are oriental, people are asian, but yes, it does sound strange; and I was referring to the fishy, dried smell... I love the contents, however)

    2. Was it warm in the room where you left the beans setting out? I would think that the beans and water would have soured by that length of time. Or had you popped them in the fridge when you decided not to cook them? I live in southern MO and even with the a.c. on, I wouldn't trust anything that had set out that long. It may be very different where you live though.

        no, they were sitting out... in Texas. Heck, they are cheap. I think I'll just toss them and start over.

      2. Beans can grow nasty bacteria if left unrefrigerated. Once they soak for a bit, they are ripe for bacterial growth. Throw 'em out. Refrigerating beans while they soak is usually recommended.

        1. Toss them. New beans are cheaper than the Dr.

          1. you soak your beans covered?

            I would soak uncovered and change the water daily.

            In a few more days, the beans may sprout.

            Sprouted beans are supposed to be healthier.

            In regards to this current batch, they should be fine.

            1. Jacques Pepin has always maintained that beans soaked even overnight likely spoil. I'd toss them.


              1. I'd definitely toss them. Something that ever smelled like dirty diapers is not going into my mouth. There's a germ in some beans that may not be killed below a hard boil, and after letting it incubate for two days, you could have a bad situation on your hands. I'd soak them in the fridge next time.

                1. I am experiencing the same problem. What bothers me most is that now that the beans are cooking they are STILL emitting a variation of the same foul odor.

                  For the record: I soak beans overnight outside of the refrigerator (in Texas) and have never had any problems whatsoever. Every now and then I forget about them and they accidentally sit out two nights, and yes the water begins to look cloudy and have a faint odor. I just rinse the beans well and they cook fine. However, the beans I usually use are pinto, black, or garbanzo.

                  This is the first time I've ever accidentally soaked navy beans for two days instead of one and I am SHOCKED by this horrible smell -- especially since the beans themselves look fine. I would bet money this is something having to do with the particular chemical makeup of Navy beans.

                    Maybe the smaller size of navy beans makes a difference, although they are close in size to black beans.

                    There is definitely a difference among been varieties when it comes to the thickness/permeability of the skin.
                    Add to that the age of the particular batch of beans you are making (regardless of variety), and it's obvious that the same soaking time can affect different batches differently. I suspect that once the interior is hydrated, fermentation/spoilage begins. I very rarely throw food out, but in your example, I would.
