Public Inquiry into Osaka City's Response to Kobayashi Pharmaceutical Claims and Food Safety Concerns

On August 11, Year 8 of the Reiwa Era, a public inquiry was submitted to Osaka City's Mayor, Hideyuki Yokoyama, representing the Osaka Restoration Association. This action was initiated by the Smoking Food Club, a company based in Hayashima Town, Okayama Prefecture, led by pharmacist Masashi Mori.

This inquiry follows a request made on August 9 to both the Prime Minister and the Minister of Consumer Affairs regarding a demand for an apology and compensation related to puberulic acid, which has garnered significant attention due to food safety concerns.

Key Findings Confirmed by Osaka City Documents



1. Origin of Puberulic Acid: The term 'puberulic acid' originated from Kobayashi Pharmaceutical's submission made on March 27, Year 6. Osaka City has acknowledged that the only documents related to puberulic acid in its possession are those submitted by Kobayashi Pharmaceutical. However, there are no records confirming the validity of these documents.

2. Lack of Verification of Contaminated Materials: It has been noted that Osaka City did not conduct a collection process regarding the bacterial strains of the red yeast mold that were alleged to be the cause of safety concerns. This raises questions about the integrity of the investigation undertaken by the city.

3. Reliance on Voluntary Information: The blue mold sent by Kobayashi Pharmaceutical's Research Institute was provided voluntarily, and there is no indication that Osaka City executed its evaluation or testing independently.

4. Toxicity Information: There was no independent examination of the toxicity data regarding puberulic acid as defined in the submissions from Kobayashi Pharmaceutical. Furthermore, no records have been disclosed that detail any testing carried out by Osaka City.

Questions Raised in the Inquiry


The public inquiry put forth three critical questions that need thorough investigation:

1. Did Osaka City accept the documents submitted by Kobayashi Pharmaceutical without any independent verification? If records exist that demonstrate verification, they should be disclosed.

2. Given that Osaka City has the authority to collect necessary samples, why would they rely on voluntarily provided materials from a company under scrutiny?

3. Will there be a re-evaluation and summary of the published information, including food poisoning reports? If errors are found, how does Osaka City plan to fulfill its obligation to communicate with affected businesses and citizens?

The deadline for responses to these questions is set for August 25, Year 8, and the city is expected to make public any responses (or lack thereof) that it receives.

Purpose of the Release


This inquiry highlights the documentation regarding Osaka City's decisions and responses as well as the content of the questions posed. It does not make definitive statements about general scientific knowledge or the causes of any health impacts related to the allegations.

Additionally, there exists a notification from the Ministry of Health, Labour and Welfare to the Osaka City Health Bureau regarding recall orders, implying that there was communication between the National Government and Osaka City, contrary to claims suggesting otherwise. The missing documents relate specifically to records concerning judgments or discussions regarding the scientific validity of the suspected harmful substances.
