Microbiological test methods for w/o formulas have raised questions in terms of their suitability. They also require a more critical view of the results than other product types. This first article in a two-part series reviews the limitations of such methods and options for their optimization. It also critically observes to what extent test results provide relevant information for an appropriate safety assessment. Part II, in August 2022, will explore a holistic approach to more accurately assess microbiological safety.
