What many people do not realize, however, is that bean sprouts can be just as dangerous as raw meat. Yes, bean sprouts. Why? Because the sprout seeds can easily become contaminated in the fields where they are grown. Bean sprouts need to be grown in a warm and moist environment. Such environments are the ideal setting for bacteria to grow, including salmonella and E. coli. Some of the sprout seeds can also become contaminated by animal manure where they are grown.
To be safe, it is best to avoid bean sprouts at restaurants because you have no way of knowing how well they were cooked, unlike meat, which you can inspect. If you want to eat bean sprouts at home, health officials suggest immersing the sprouts in boiling water and cooking them thoroughly to kill harmful bacteria.
