    There was just tiny mention of at home sprouts containing this bacteria in the “nooks and crannies of the seed” itself.
    Would this apply to organically grown seeds? I’ve always sprouted seeds at home, without problems, always organic. If I soak seeds with vinegar added to soaking water, would that not kill the bacteria?

    • Michael Greger M.D.

      Even soaking seeds in a bleach solution may not guarantee safety. I would encourage you to move to a “nookless” seed like broccoli.

    • fineartmarcella

      I would think you would kill the seed if you soaked it in the high acid vinegar, don’t know, just thinking, it killed my live sprouts when I accidentally put half a cup of vinegar in the auto spouter’s water instead of half a cup of Hydrogen Peroxide…

    i sproute alfalfa seeds at home too, is there any trick to be safe? or may be same contamination from time to time is good to our organism to be aware?

    Thank you

  • Lindydio

    I always grow my own alfalfa sprouts

    I soak them for approx 10 minutes in clean water, then
    rinse, add more fresh water and a 1/2 capful of H202 (food grade hydrogen peroxide)
    Let soak ovenight
    Rinse several times a day until ready

    SHAME ON YOU for Lying to people!!  Thousands of us who have “done our homework” have discovered that the Reason for Existence of federal agencies like FDA and CDC, is to slant the truth to support commercial producers of often toxic, always less than nutritious things that wise people do not even call food. They are there to prop up the business of food processing, regardless of how it harms people – for Money! Furthermore, the administrations of these federal agencies have been caught repeatedly violating the strong negative recommendations of THEIR OWN FOOD CHEMISTS !!!  …saying that neurotoxins like Neotame, Aspartame, and Sucralose are Good for health, when they KNOW Positively that they’re serously harmful. Repent of your part in the Lies that Harm people !!  Do you really believe that you will ultimately “get away with” this evil?  Tell the Truth!

       Although I share your concerns about the ties of federal agencies such as the CDC, FDA and USDA with corporations I’m not sure what “lies” you think NutritionFacts.org are spreading. Dr. Greger cites well done scientific studies. The video on Aspartame shows that it is harmful see… http://nutritionfacts.org/video/is-nutrasweet®-bad-for-you/ and the one that covers a range of artificial sweeteners Sucralose see… http://nutritionfacts.org/video/a-harmless-artificial-sweetener/ along with the recent video on Stevia see… http://nutritionfacts.org/video/is-stevia-good-for-you/. I guess I disagree with your interpretation of the videos which I take to show clearly that consumers should avoid all artificial sweeteners and if they use sweeteners they should probably go with either  date sugar or molasses see… http://nutritionfacts.org/video/the-healthiest-sweetener/. The avoidance of sweeteners also relates to the amount of fructose. We use glucose in all our cells but fructose is metabolized by the liver into products that are not healthy. It gets complex and the science keeps changing so you need to keep tuned in as you never know when recommendations will change and we will develop a better understanding of the complexities of human nutrition.

      I think your very valid criticism is misdirected. Have you looked over/read the information on this site?

    Does this cover all sprouts or just alfalfa? I’m hoping some are safe. Thank you for all your work, it’s hands down the best website I’ve ever been lucky enough to come across.

  • David Paradine

    And I revoke my question. De anyone wondering, the answers to safe sprouts is in the last link.

  • Paulina

    I plant alfalfa sprouts at home, and i have one question, what about sprouting alfalfa with red raddish? Red raddish sprouts are considered as antibacterial and inhibits growth of mold.

    I just want to say thanks for all the GREAT INFORMATION you share on your site! I’m a research psychologist (I research nutrition and health behavior) and I appreciate your research/evidence based approach to nutrition. I just read a comment by someone who sounded completely ignorant. Please know that there are many of us out there who are thankful for what you do. Best nutrition site I’ve ever found, by far. Kudos on a job well done. Keep it up!

    • http://nutritionfacts.org/ Michael Greger M.D.

      You are so sweet! Thank you so much for your kind words. So glad I can help. The nutritional science is just the first half though–we need social psychologists to help develop strategies to convince people to actually adopt healthier habits!

    dr. gregor, i love your videos, but i have to SERIOUSLY question this one. do you make your own sprouts? if so, where does the fecal matter come from? i don’t add fecal matter to my alfalfa sprouts. do you? and if so, why do you? please know that i am laughing as i write this. alfalfa sprouts grown in a jar with a mesh lid are exposed only to water – unless you add your own fecal matter to the water. ??? i question this… now i am wondering if i need to question more of your data in other videos. ???

  • Jeanjean Laurendeau

    tell me how alfafa sprouts get into fecal bacteria when and how?????

  • Joel Garcia

    Doc: Your intent to inform and teach, specially the way you convey information is remarkable. Love the power points and your evidence based studies. The calm voice is inspiring.
    I understand sprouts bought in a store or mass produced has the same shortcomings of the dairy, meat and even vegetable industries. Spinach, Bird flu, Mad Cow disease are all expression of a non sustainable system which is used and abused with hormones, steroids and herbicides, respectively.

    Alfalfa sprouts happens to be one of the most alkalizing micro greens available. It supports renal elimination and metabolic waste neutralization among the dozens of enzymes, natural growth hormones and minerals it contains. In fact, any sprout will have this characteristic since the young shoot is quickly growing. We cannot question nature… only question how man interferes with nature. If correctly sprouted, it is a superfood.

    I believe in a more sustainable, nutritious and whole food based diet, as I am sure you do!

    The CDC and FDA are agencies which protect the public to a certain extent, but really, what do they know of superior nutrition.

    Your video is wonderful and I would like the message to retain its purity. People want information to improve their health, lets give it to them.

  • Blow your head off

    I’m sick of these so called doctor’s try to sucker people when you should be helping people but that’s the wait is now, you can keep giving out bogus information for profit.

    • Toxins

      No profit is had here at nutritionfacts.org, its purely donation run. Furthermore, all the information here is backed with scientific evidence and the evidence is available for viewing in the sources cited section below the video.

  • Gianluca

    Do you mean dangerous only alfa alfa sprouts obtained using just seeds or even using the raw whole alfa alfa herb ?

  • Pitt

    http://www.cdc.gov/features/dsfoodborneoutbreaks/ “A large outbreak of Salmonella infections in 2010 caused nearly 2000 illnesses. Among the outbreaks attributed to a food vehicle composed of ingredients from only one of 17 defined food commodities, the commodities most often implicated were beef (13%), dairy (12%, nearly all unpasteurized), fish (12%), and poultry (11%).”

    Been eating alfalfa, raw mushrooms and every other edible raw vegetable there is my whole life…. never sick once from that, nor do I know someone getting sick from such either. In contrast, I have gotten sick twice (Burger and Fajita) no sprouts there. There is a risk in every single bite of food we eat unless we eat synthetic “glow in the dark” foods. Placing an article saying DON’T EAT RAW ALFALFA SPROUTS sound very uneducated. Instead, provide solutions from avoiding contamination or dealing with it should be more appropriated coming from a passionate nutrition professional, such as combine the consumption of alfalfa sprouts with properly cleaned cilantro http://en.wikipedia.org/wiki/Coriander “Chemicals derived from coriander leaves were found to have antibacterial activity against Salmonella choleraesuis, and this activity was found to be caused in part by these chemicals acting as nonionic surfactants”

    Thanks for your informative videos. But I don´t understand..where is the salmonella coming from? We know how its get into chicken or hamburger meat. How and at what point is the bacteria getting into the sprouts? As you may recall sprouts were claimed to be responsible for the death of over forty people in Germany a couple of years ago. But it was not caused directly by the grower of the bio sprouts here in Germany but was traced back to the seed?? company in Egypt. So is it the seeds or what? Thanks again!!
