A Rapid Phosphomonoesterase Test for Control of Dairy Pasteurization

Although health authorities seek to carefully define the requirements of pasteurization by means of ordinances, they are repeatedly confronted by failures to comply with regulations. The human element involved in the pasteurizing process and many of the mechanical factors contributing to improper pasteurization cannot be satisfactorily controlled by routine physical inspection of plants. Temperature recording devices may become inaccurate or inoperative between the visits of plant inspectors. Some defects are apparent only to an inspector who has studied the many and complex types of pasteurizing systems and individual equipment utilized. Other irregularities cannot be detected visually.
