Additional information

This assay is used to determine the number of aerobic mesophilic (growth at body temperatures i.e. 35° C) bacteria contained in a food product or ingredient.

No information about potential foodborne pathogens can be inferred from aerobic plate counts. Some foods (raw meats, raw commodities) may naturally contain high levels of aerobic mesophilic bacteria.
