A filling machine and a filling monitoring method are provided which can monitor the condition of a pressure roller and do not deteriorate the quality of fluid food. The filling machine includes a first rotary member rotatably disposed at the inside of the joining surface of a longitudinally sealed portion of a packaging material ( 11 ) being fed; a second rotary member rotatably disposed in opposition to the first rotary member with the packaging material ( 11 ) pinched therebetween; a rotation detection signal generator for generating a rotation detection signal in association with rotation of at least one of the first and second rotary members; and monitoring processing means for reading the rotation detection signal and detecting abnormality of rotation of at least one of the first and second rotary members. Since abnormality of rotation of at least one of the first and second rotary members is detected on the basis of the rotation detection signal, the following problem is prevented: damage to the inner surfaces of the packaging material ( 11 ) and a strip tape, or separation of a sticking resin piece and dropping of the resin piece into fluid food contained in the packaging material ( 11 ), with a resultant deterioration in quality of the fluid food.
