A dilution buffer for suspension and an enumeration method, which, for the measurement of the viable cell count of a microorganism contained within a sample, and particularly a powdered product such as a milk powder, yield more accurate measurement values than have conventionally been obtainable. A dilution buffer for suspension, used for preparing a suspension buffer of a sample when conducting a measurement of the viable cell count of a microorganism contained within the sample, wherein the dilution buffer contains polysorbates at a concentration of not less than 0.5%. Also, an enumeration method for a microorganism contained within a sample, the method including: preparing a suspension buffer of the sample using a dilution buffer for suspension containing polysorbates at a concentration of not less than 0.5%, and measuring the viable cell count of the microorganism contained within the suspension buffer.
