Detecting and sampling method for microorganisms in food and sampling box thereof

The invention discloses a detecting and sampling method for microorganisms in food and sampling box thereof. The method comprises the steps that a collected sample is placed in a test tube, the depth of a contact base is adjusted, and the depth of the contact base is adjusted according to the length of the used test tube; then the test tube is inserted into a test tube placing groove, a pressing sleeve is pushed to sleeve the top end of the test tube through a bearing plate, and meanwhile, a pushing spring in the pressing sleeve pushes a pressing plate to press the top end of the test tube; and finally, ice bags can be placed in rectangular blind grooves as needed. According to the sampling box for food microorganism detection, the top of the test tube can be pressed after the test tube is placed, so high stability is obtained, and transportation safety is also improved; the depth of the test tube placing groove can be conveniently adjusted, so the sampling box can be conveniently applied to test tubes with v
