Raw materials used in health foods are manufactured from the same strain. An unexpected ingredient that appears to be "acid" has been confirmed.
People who ingested health foods containing the ingredients of Kobayashi Pharmaceutical's "Red Yeast'' developed kidney disease. It is expected that efforts will be made to determine the cause, including the possibility that it may have been mixed in during the manufacturing process. The company uses two different strains of Monascus mold depending on the type of product, and found that 33 lots of red yeast rice ingredients manufactured last year and used for this health food etc. were all strains ofMonascus mold.
