Abstract: A method for producing dry earthworm powder, by which dry earthworm powder having high-titer enzymes can be produced while removing toxic substances contained in the bodies of earthworms, is provided. The method comprises: contacting a live earthworm with a chloride(s) of at least one metal selected from the group consisting of potassium, sodium, magnesium and calcium; and subsequently contacting the live earthworm with powder of a hydroxycarboxylic acid(s) and diluting the resulting mixture with water to adjust pH to 2 to 5, followed by leaving the live earthworm to stand for 3 to 180 minutes, washing the live earthworm with water, grinding the washed live earthworm and freeze-drying the obtained ground product.
