m FC Agar is used with rosolic acid for the detection and enumeration of fecal coliforms by membrane filtration in a laboratory setting. m-FC Agar is not intended for use in the diagnosis of disease or other conditions in humans.

Geldreich et al. formulated a medium to enumerate fecal coliforms (FC) using the membrane filter (m) technique without prior enrichment.

Many standard method membrane filtration procedures recommend m-FC media for testing water. The American Public Health Association (APHA) specified m-FC media and incubation at 44.5 ± 0.5°C in the fecal coliform procedure and other tests. The Association of Official Analytical Chemists (AOAC) specifies m-FC Agar for detecting total coliforms and fecal coliforms in foods. The US Environmental Protection Agency specified using m-FC media in fecal coliform methods for testing water by the direct MF method or the delayed-incubation MF methods.
