Regulatory Milk Lab Services

The Regulatory Services’ Milk Laboratory primarily monitors Kentucky Milk Haulers by analyzing the components of individual producer’s milk samples collected by a hauler along his or her route. This will help to ensure accurate collection techniques by the hauler, which in turn will safeguard that Kentucky Producers are being paid fair prices for their milk.

In general, our services are limited to producer bulk tank samples and bulk unit samples from processors. Typically there is no fee associated with samples submitted to the lab for routine testing, provided the samples are from Kentucky producers, processors or allied industry representatives. Samples should be obtained and submitted to the lab by properly licensed milk samplers using approved milk sampling and sample handling procedures.

Service Milk Quality Testing (Section 6 and Appendix N):
Dairy producers and processors are required by the Pasteurized Milk Ordinance (PMO) and its supporting documents to conduct certain milk tests on a routine basis. The tests are food safety related and required to ensure consumers a safe supply of dairy products. The Milk Laboratory at Regulatory Services is an approved Interstate Milk Shipments (IMS) listed facility (IMS Lab # 21011) for select tests. The lab provides these testing services for a fee. These services are provided to assist Kentucky producers and processors with compliance with the PMO and its supporting documents. As with other types of official milk samples, only licensed and approved milk samplers may submit these samples to our lab. The fee schedule for these tests is outlined below :

Antibiotic (Charm SL) Appendix N: $8.00
Aerobic Bacteria Count (Petrifilm™/PAC) $8.00
Electronic Somatic Cell Count (ESCC): $8.00
Direct Microscopic Somatic Cell Count (DMSCC): $8.00
Freezing Point Depression (Cryoscope): $8.00
Section 6 testing (also known as "monthly regulatory sample" includes Antibiotic, SPC, SCC and FPD): $28.00

Proper Milk Sample Transport:

All milk samples transported to the Regulatory Services’ Milk Laboratory for regulatory or quality testing must be stored properly in a cooler that maintains a sample’s temperature of 0.0 to 4.5°C. This temperature is critical in order to maintain the integrity of the sample, and therefore, allowing for the most accurate results. It is recommended that milk samples are shipped in a 2 or 3 ounce sealed vial secured in a floater with an equal mixture of ice and water. A temperature control sample must accompany all samples. If the temperature control sample in not within the recommended temperature range of 0.0 to 4.5°C, all samples will be rejected and not analyzed. For any questions pertaining to proper sample collection, transport and analysis, please contact the Milk Laboratory office:

Other Types of Dairy Testing
Occasionally we receive requests to perform testing that exceeds our capacity or our capabilities. When this occurs, we refer these requests to a list of alternative laboratories. This dairy laboratory resource listing was compiled by Regulatory Services personnel at the request of the Kentucky Milk Handlers Advisory Board. It is intended to provide Kentucky dairy industry representatives with a basic list of alternative dairy laboratories along with a general description of services provided by each listed lab.

This listing is for informational purposes only and is not intended to be a comprehensive reference of all US dairy labs. A lab's appearance on this list does not constitute an endorsement. Information regarding specific testing procedures and costs should be directed to each specific lab. Suggested amendments to this document should be directed to Regulatory Services' Milk Program at E-Mail or 859-257-2785.
