In the case of people who took Kobayashi Pharmaceutical's supplements developing kidney disease, it is believed that unexpected ingredients may have been mixed in during the manufacturing process of the red yeast rice raw material. In an interview with the company, we learned that samples of the product that are still in the process of being manufactured are being stored. This is expected to provide clues as to which process the product was contaminated with.
Kobayashi Pharmaceutical keeps samples of the red yeast rice raw material manufactured at its Osaka factory for each lot of a certain amount, and it is assumed that samples from 10 lots out of 88 lots manufactured in the past year appear to be pueruric acid. I found an ingredient that does not.
It is believed that the ingredients may have been mixed in during the manufacturing process of the red yeast rice ingredient, but it is not known in which process the ingredients were mixed.
According to the company, the manufacturing process is mainly divided into two parts: ``cultivation'' and ``formulation,'' and even in the ``cultivation'' process, samples that are still being manufactured are stored for each lot.
The Ministry of Health, Labor and Welfare and Osaka City are investigating the cause of the incident by visiting the factory and interviewing the company.
Analyzing samples during production is expected to provide clues as to which process the contamination occurred.
