EM Counts and excursion
Environmental monitoring (EM) is a tool utilized by the pharmaceutical industry to measure and monitor microbial bioburden levels in a manufacturing facility. Periodic sampling of the air and surfaces within controlled environments allows the microbiologist to determine the approximate number and types of microorganisms present in a given area over a defined period of time. This data is analyzed through a process known as trending. Trending is performed in order to detect fluctuations in microbial levels, and allow firms to ensure that these levels remain within acceptable parameters. “Traditional” methods of trending EM data often include the use of excursion rates. “Excursion rate”, for the purpose of this article, is defined as the percentage of the total number of collected EM samples with counts exceeding either the alert or action level.
