Method Description

Samples are prepared and dilutions made. The samples are then plated on media and incubated based on method specifications. After incubation plates are read and results generated based on countable range

Additional Information

A mold is a fungus that grows in the form of multicellular filaments. Molds are spread by spores which can be transmitted by air, water, or even insects.
Molds are known to cause respiratory problems and allergies, although in the right conditions, some molds can produce mycotoxins that can cause illness.
These procedures listed above enumerate the amount of mold present in a sample using a spread plate, pour plate, petrifilm or air sediment method.
Also see Yeast, as these tests are typically performed together.
