MAFF Denies Using the Term 'Puberulic Acid' in Disclosure, While MHLW States 'No Fact of Publication as a Causative Agent'

Kunsei Club Co., Ltd. sent a public inquiry to the Ministry of Agriculture, Forestry and Fisheries (MAFF) on June 1, 2026, citing contradictions between MAFF and the Ministry of Health, Labour and Welfare (MHLW) regarding the Beni-koji incident. MAFF refused a disclosure request, stating it 'has not used the term puberulic acid in information for consumers,' yet the term is explicitly listed as a risk management target in MAFF's own committee documents. Meanwhile, the MHLW stated it 'has not published the fact that puberulic acid is a causative agent,' highlighting a discrepancy between the two ministries. The company has requested an explanation by June 10.
