Certain bacteria can be safely consumed as human food
Multiple scientific studies demonstrate that certain bacteria, yeasts, and fungi are safely and beneficially consumed as human food, particularly through fermentation and probiotic products.
The claim that certain bacteria can be safely consumed as human food is specific and empirically verifiable. The retrieved literature includes multiple peer-reviewed papers discussing the safe consumption of fermented foods containing lactic acid bacteria, probiotic strains, and fungal biomass (e.g., papers 0, 2, 4, 9). No papers refute the core claim. Therefore, the balance verdict is SUPPORTED.
