Ms. Yupa Laojindapun Member and Secretary Office of Standard Development, National Bureau of Agricultural Commodity and Food Standards (3) The Ministry of Agriculture and Cooperatives has announced the Thai Agricultural Standard on raw cow milk (TAS. 6003-2005) since B.E. 2548 (2005). At present, the information and relevant regulations on raw milk have been changed over time, in addition to that, the production of raw milk from other animals such as goat and buffalo are significantly increasing. The Agricultural Standards Committee deems it necessary to review this standard so as to appropriately improve raw cow milk quality and promote milk trade. In consequence of this review, the original TAS. 003-2005 is repealed and the updating standard of TAS 6003-2010 is issued instead. This standard is based on the following documents: Ministry of Agriculture and Cooperatives. B.E. 2552 (2009).

By virtue of Section 5, Section 15 and Section 16 of the Agricultural Standards Act B.E. 2551 (2008), the Minister of Agriculture and Cooperatives hereby issues this Notification on Establishment of Thai Agricultural Standard: Raw Cow Milk as follows: 1. The Notification of the National Committee on Agricultural Commodity and Food Standards entitled the establishment of Thai Agricultural Commodity and Food Standard: Raw Cow Milk, dated 5 August B.E. 2548 (2005) is repealed. 2. The Thai Agricultural Standard for Raw Cow Milk (TAS 6003-2010) is established as a voluntary standard, details of which are attached herewith. Notified on 26 August B.E. 2553 (2010) (Mr. Theera Wongsamut) Minister of Agriculture and Cooperatives TAS 6003-2010 THAI AGRICULTURAL STANDARD RAW COW MILK 1 SCOPE 1.1 This Agricultural Standard refers to raw milk from dairy cows intended for food processing. 1.2 This Agricultural Standard should be used jointly with the Thai Agricultural Standard on Good Agricultural Practices for Dairy Cattle Farm. 2 DEFINITIONS For the purpose of this standard: Raw cow milk means milk from dairy cow not less than 3 days after parturition and shall not contain colostrum.
