A colony-forming unit (CFU, cfu, Cfu) is a unit used in microbiology to estimate the number of viable bacteria or fungal cells in a sample. Viable is defined as the ability to multiply via binary fission under the controlled conditions. Counting with colony-forming units requires culturing the microbes and counts only viable cells, in contrast with microscopic examination which counts all cells, living or dead. The visual appearance of a colony in a cell culture requires significant growth, and when counting colonies it is uncertain if the colony arose from one cell or a group of cells. Expressing results as colony-forming units reflects this uncertainty.
A designated space that is closely controlled for compliance to limitations that have been outlined for operating procedures, air cleanliness, air pressure, temperature, relative humidity, and air flow patterns. A number of devices and procedures are often used in a cleanroom to monitor the viability of airborne particles.

Cleanroom classification – Grade A, B, C or D
Grades A through to D refer to cleanroom cleanliness for the Pharmaceutical Industry for European, Australian and some Asian countries. Grade A is the cleanest, for sterile operations, through to Grade D for packing or support operations. These Grades can be related to the ISO Classes.
Cleanroom classification – ISO Class Classification system
used to determine the acceptable concentration of particles in an identified volume of air given specific particle size parameters. Classification levels are determined by the federal government. The primary authority in the US and Canada is the ISO classification system ISO 14644-1. This standard includes the cleanroom classes ISO 1, ISO 2, ISO 3, ISO 4, ISO 5, ISO 6, ISO 7, ISO 8 and ISO 9, with ISO 1 being the “cleanest” and ISO 9 the “dirtiest” class (but still cleaner than a regular room). The most common classes are ISO 7 and ISO 8.
A space or system of spaces in which there are tightly controlled limits that govern air flow, air pressure, air filtration, temperature, relative humidity, viability of airborne particles, access, and operating procedures.

Cleanroom and Controlled Environment Consulting.
In the pharmaceutical industry, one term is becoming increasingly important: containment. It describes the process of containing a substance within a defined space, a method that is suitable for protecting operators and the environment in case of high toxicity and product reactivity. At the same time, containment prevents dust, gases or vapours from being released into the environment and contaminating the product.
A process that includes a level of sterilization with a 6-log or higher kill
Difference Between a Controlled Environment and a Cleanroom What’s a controlled environment?
A controlled environment, or critical environment, is an area that must have certain parameters controlled, specifically, pressure, temperature, and segregation. Many laboratories are considered controlled environments, as they have controlled temperature and pressure and are separated from other operations, such as manufacturing or shipping. Unlike cleanrooms, controlled environments do not necessarily have to meet certain standards for particle contamination.What’s a cleanroom?
A cleanroom is a type of controlled environment, but one with much more stringent requirements. Cleanrooms require temperature and pressure control, as well as separation from the outside environment and other operations, but these things must be controlled to specific standards. Cleanrooms are classified by the maximum acceptable numbers of particles (by size) in the air per cubic meter, and must be regularly tested to ensure compliance to that standard (see more about cleanroom classifications here). Compared with other controlled environments, cleanrooms may require more energy, air, and advanced technology to maintain the cleanroom conditions.

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.
The U.S. Food and Drug Administration (FDA) signed an arrangement with the Canadian Food Inspection Agency (CFIA) and the Department of Health Canada (Health Canada) recognizing each other's food safety systems as comparable to each other.

GMP Good Manufacturing Practice -GMP is also sometimes referred to as "cGMP". The "c" stands for "current"- is a system for ensuring that products are consistently produced and controlled according to quality standards. It is designed to minimize the risks involved in any pharmaceutical production that cannot be eliminated through testing the final product.

A test that samples a fixed volume of air and captures, filters and counts particles by their size. This is performed when the cleanroom is “at rest” or “in operation”. For pharmaceutical operations, both viable (alive) and non-viable (not alive) particle counts are performed. This is performed as part of the certification of a cleanroom and during regular environmental monitoring.
