Microbiological Analysis
Parameter Units of Measure Limits
Standard plate count CFU/g 10,000 maximum
Yeast and mold CFU/g 50 maximum
Coliforms (1) CFU/g 10 maximum
Enterobacteriaceae (1) CFU/g 10 maximum
Salmonella CFU/sample (2) not detected

(1) The food industry is trending toward Enterobacteriaceae (“EB”) as the most commonly used category of indicator organisms for gauging general process sanitation.  For compliance to this Standard, either coliforms and/or EB shall be utilized, at the discretion of the manufacturer.

(2) Typical minimum sample size for Salmonella testing is 25 g, but the exact sample size and methodology is left to the discretion of the manufacturer.

(3) Where the effective limit of quantitation for the test is 10 CFU/g (such as when a dilution factor of 10 is applied) then the test result must be not detected in order to comply with this Standard.  Where the testing method is capable of quantifying microbial counts below 10 CFU/g, then a compliant result must be a value less than 10 CFU/g.

Permissible Additives

Milk Minerals may be pH adjusted with an appropriate mineral or organic acid or base.  Any pH adjustment agent used for this purpose shall be food grade and shall be used in accordance with U.S. current Good Manufacturing Practices and in accordance with its GRAS status, where applicable.
