No. To our knowledge, there are no known cases of yeast causing infections in a healthy person. In this discussion, it is important not to confuse the common baker’s yeast strain Saccharomyces cerevisiae with infections caused by candida yeast. Yeast is a generic name that includes a multitude of species, including Candida albicans. Candida albicans is completely different from baker’s yeast and is not used in food. The use of yeast (Saccharomyces cerevisiae) in food is safe and has been harmlessly used for millenniums.
